      alpha: switch to dynamic percpu allocator · 9b7dbc7d
      Tejun Heo 提交于
      Alpha implements custom SHIFT_PERCPU_PTR for modules because percpu
      area can be located far away from the 4G area where the module text is
      located.  The custom SHIFT_PERCPU_PTR forces GOT usage using ldq
      instruction with literal relocation; however, the relocation can't be
      used with dynamically allocated percpu variables.  Fortunately,
      similar result can be achieved by using weak percpu variable
      definitions.
      
      This patch makes alpha use weak definitions and switch to dynamic
      percpu allocator.
      
      asm/tlbflush.h was getting linux/sched.h via asm/percpu.h which no
      longer needs it.  Include linux/sched.h directly in asm/tlbflush.h.
      
      Compile tested.  Generation of litereal relocation verified.
      
      This patch is based on Ivan Kokshaysky's alpha percpu patch.

      percpu: use dynamic percpu allocator as the default percpu allocator · e74e3962
      Tejun Heo 提交于
      This patch makes most !CONFIG_HAVE_SETUP_PER_CPU_AREA archs use
      dynamic percpu allocator.  The first chunk is allocated using
      embedding helper and 8k is reserved for modules.  This ensures that
      the new allocator behaves almost identically to the original allocator
      as long as static percpu variables are concerned, so it shouldn't
      introduce much breakage.
      
      s390 and alpha use custom SHIFT_PERCPU_PTR() to work around addressing
      range limit the addressing model imposes.  Unfortunately, this breaks
      if the address is specified using a variable, so for now, the two
      archs aren't converted.
      
      The following architectures are affected by this change.
      
      * sh
      * arm
      * cris
      * mips
      * sparc(32)
      * blackfin
      * avr32
      * parisc (broken, under investigation)
      * m32r
      * powerpc(32)
      
      As this change makes the dynamic allocator the default one,
      CONFIG_HAVE_DYNAMIC_PER_CPU_AREA is replaced with its invert -
      CONFIG_HAVE_LEGACY_PER_CPU_AREA, which is added to yet-to-be converted
      archs.  These archs implement their own setup_per_cpu_areas() and the
      conversion is not trivial.
      
      * powerpc(64)
      * sparc(64)
      * ia64
      * alpha
      * s390
      
      Boot and batch alloc/free tests on x86_32 with debug code (x86_32
      doesn't use default first chunk initialization).  Compile tested on
      sparc(32), powerpc(32), arm and alpha.
      
      Kyle McMartin reported that this change breaks parisc.  The problem is
      still under investigation and he is okay with pushing this patch
      forward and fixing parisc later.

      container freezer: implement freezer cgroup subsystem · dc52ddc0
      Matt Helsley 提交于
      This patch implements a new freezer subsystem in the control groups
      framework.  It provides a way to stop and resume execution of all tasks in
      a cgroup by writing in the cgroup filesystem.
      
      The freezer subsystem in the container filesystem defines a file named
      freezer.state.  Writing "FROZEN" to the state file will freeze all tasks
      in the cgroup.  Subsequently writing "RUNNING" will unfreeze the tasks in
      the cgroup.  Reading will return the current state.
      
      * Examples of usage :
      
         # mkdir /containers/freezer
         # mount -t cgroup -ofreezer freezer  /containers
         # mkdir /containers/0
         # echo $some_pid > /containers/0/tasks
      
      to get status of the freezer subsystem :
      
         # cat /containers/0/freezer.state
         RUNNING
      
      to freeze all tasks in the container :
      
         # echo FROZEN > /containers/0/freezer.state
         # cat /containers/0/freezer.state
         FREEZING
         # cat /containers/0/freezer.state
         FROZEN
      
      to unfreeze all tasks in the container :
      
         # echo RUNNING > /containers/0/freezer.state
         # cat /containers/0/freezer.state
         RUNNING
      
      This is the basic mechanism which should do the right thing for user space
      task in a simple scenario.
      
      It's important to note that freezing can be incomplete.  In that case we
      return EBUSY.  This means that some tasks in the cgroup are busy doing
      something that prevents us from completely freezing the cgroup at this
      time.  After EBUSY, the cgroup will remain partially frozen -- reflected
      by freezer.state reporting "FREEZING" when read.  The state will remain
      "FREEZING" until one of these things happens:
      
      	1) Userspace cancels the freezing operation by writing "RUNNING" to
      		the freezer.state file
      	2) Userspace retries the freezing operation by writing "FROZEN" to
      		the freezer.state file (writing "FREEZING" is not legal
      		and returns EIO)
      	3) The tasks that blocked the cgroup from entering the "FROZEN"
      		state disappear from the cgroup's set of tasks.

      avoid overflows in kernel/time.c · bdc80787
      H. Peter Anvin 提交于
      When the conversion factor between jiffies and milli- or microseconds is
      not a single multiply or divide, as for the case of HZ == 300, we currently
      do a multiply followed by a divide.  The intervening result, however, is
      subject to overflows, especially since the fraction is not simplified (for
      HZ == 300, we multiply by 300 and divide by 1000).
      
      This is exposed to the user when passing a large timeout to poll(), for
      example.
      
      This patch replaces the multiply-divide with a reciprocal multiplication on
      32-bit platforms.  When the input is an unsigned long, there is no portable
      way to do this on 64-bit platforms there is no portable way to do this
      since it requires a 128-bit intermediate result (which gcc does support on
      64-bit platforms but may generate libgcc calls, e.g.  on 64-bit s390), but
      since the output is a 32-bit integer in the cases affected, just simplify
      the multiply-divide (*3/10 instead of *300/1000).
      
      The reciprocal multiply used can have off-by-one errors in the upper half
      of the valid output range.  This could be avoided at the expense of having
      to deal with a potential 65-bit intermediate result.  Since the intent is
      to avoid overflow problems and most of the other time conversions are only
      semiexact, the off-by-one errors were considered an acceptable tradeoff.
      
      At Ralf Baechle's suggestion, this version uses a Perl script to compute
      the necessary constants.  We already have dependencies on Perl for kernel
      compiles.  This does, however, require the Perl module Math::BigInt, which
      is included in the standard Perl distribution starting with version 5.8.0.
      In order to support older versions of Perl, include a table of canned
      constants in the script itself, and structure the script so that
      Math::BigInt isn't required if pulling values from said table.
      
      Running the script requires that the HZ value is available from the
      Makefile.  Thus, this patch also adds the Kconfig variable CONFIG_HZ to the
      architectures which didn't already have it (alpha, cris, frv, h8300, m32r,
      m68k, m68knommu, sparc, v850, and xtensa.) It does *not* touch the sh or
      sh64 architectures, since Paul Mundt has dealt with those separately in the
      sh tree.

      really shouldn't exist in a file like kernel/Kconfig.instrumentation.
      
      It would be much better to do
      
              depends on ARCH_SUPPORTS_KPROBES

      ALPHA: support graphics on non-zero PCI domains · 025a2215
      Jay Estabrook 提交于
      This code replaces earlier and incomplete handling of graphics on non-zero PCI
      domains (aka hoses or peer PCI buses).
      
      An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a
      kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose
      SRM consoles are capable of configuring and handling graphics options on
      non-zero hoses.  All other machines have the option set FALSE.
      
      A routine, "find_console_vga_hose()", is used to find the graphics device
      which the machine's firmware believes is the console device, and it sets a
      global (pci_vga_hose) for later use in managing access to the device.  This is
      called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a
      custom version of this routine because of extra complexity.
      
      A routine, "locate_and_init_vga()", is used to find the graphics device and
      set a global (pci_vga_hose) for later use in managing access to the device, in
      the case where "find_console_vga_hose" has failed.
      
      Various adjustments are made to the ioremap and ioportmap routines for
      detecting and translating "legacy" VGA register and memory references to the
      real PCI domain.

      [PATCH] Set CONFIG_ZONE_DMA for arches with GENERIC_ISA_DMA · 5ac6da66
      Christoph Lameter 提交于
      As Andi pointed out: CONFIG_GENERIC_ISA_DMA only disables the ISA DMA
      channel management.  Other functionality may still expect GFP_DMA to
      provide memory below 16M.  So we need to make sure that CONFIG_ZONE_DMA is
      set independent of CONFIG_GENERIC_ISA_DMA.  Undo the modifications to
      mm/Kconfig where we made ZONE_DMA dependent on GENERIC_ISA_DMA and set
      theses explicitly in each arches Kconfig.
      
      Reviews must occur for each arch in order to determine if ZONE_DMA can be
      switched off.  It can only be switched off if we know that all devices
      supported by a platform are capable of performing DMA transfers to all of
      memory (Some arches already support this: uml, avr32, sh sh64, parisc and
      IA64/Altix).
      
      In order to switch ZONE_DMA off conditionally, one would have to establish
      a scheme by which one can assure that no drivers are enabled that are only
      capable of doing I/O to a part of memory, or one needs to provide an
      alternate means of performing an allocation from a specific range of memory
      (like provided by alloc_pages_range()) and insure that all drivers use that
      call.  In that case the arches alloc_dma_coherent() may need to be modified
      to call alloc_pages_range() instead of relying on GFP_DMA.

      	ilog2_u64()	Log base 2 of u64
      
      These facilities can either be used inside functions on dynamic data:
      
      	int do_something(long q)
      	{
      		...;
      		y = ilog2(x)
      		...;
      	}
      
      Or can be used to statically initialise global variables with constant values:
      
      	unsigned n = ilog2(27);
      
      When performing static initialisation, the compiler will report "error:
      initializer element is not constant" if asked to take a log of zero or of
      something not reducible to a constant.  They treat negative numbers as
      unsigned.
      
      When not dealing with a constant, they fall back to using fls() which permits
      them to use arch-specific log calculation instructions - such as BSR on
      x86/x86_64 or SCAN on FRV - if available.

      [PATCH] Configurable NODES_SHIFT · c80d79d7
      Yasunori Goto 提交于
      Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for
      each arch.  Its definition is sometimes configurable.  Indeed, ia64 defines 5
      NODES_SHIFT values in the current git tree.  But it looks a bit messy.
      
      SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has
      been changeable by config.  Suitable node's number may be changed in the
      future even if it is other architecture.  So, I wrote configurable node's
      number.
      
      This patch set defines just default value for each arch which needs multi
      nodes except ia64.  But, it is easy to change to configurable if necessary.
      
      On ia64 the number of nodes can be already configured in generic ia64 and SN2
      config.  But, NODES_SHIFT is defined for DIG64 and HP'S machine too.  So, I
      changed it so that all platforms can be configured via CONFIG_NODES_SHIFT.  It
      would be simpler.

      [PATCH] Kconfig fix (BLK_DEV_FD dependencies) · a08b6b79
      viro@ZenIV.linux.org.uk 提交于
      Sanitized and fixed floppy dependencies: split the messy dependencies for
      BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making
      BLK_DEV_FD depend on that one and taking declarations of ARCH_MAY_HAVE_PC_FDC
      to arch/*/Kconfig.  While we are at it, fixed several obvious cases when
      BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h
      are *not* going to have floppy.c compile, let alone work).
      
      If you can come up with better name for that ("this architecture might
      have working PC-compatible floppy disk controller"), you are more than
      welcome - just s/ARCH_MAY_HAVE_PC_FDC/your_prefered_name/g in the patch
      below...

      [NET]: add a top-level Networking menu to *config · d5950b43
      Sam Ravnborg 提交于
      Create a new top-level menu named "Networking" thus moving
      net related options and protocol selection way from the drivers
      menu and up on the top-level where they belong.
      
      To implement this all architectures has to source "net/Kconfig" before
      drivers/*/Kconfig in their Kconfig file. This change has been
      implemented for all architectures.
      
      Device drivers for ordinary NIC's are still to be found
      in the Device Drivers section, but Bluetooth, IrDA and ax25
      are located with their corresponding menu entries under the new
      networking menu item.

      [PATCH] ISA DMA Kconfig fixes - part 1 · 5cae841b
      Al Viro 提交于
      A bunch of drivers use ISA DMA helpers or their equivalents for
      platforms that have ISA with different DMA controller (a lot of ARM
      boxen).  Currently there is no way to put such dependency in Kconfig -
      CONFIG_ISA is not it (e.g.  it is not set on platforms that have no ISA
      slots, but have on-board devices that pretend to be ISA ones).
      
      New symbol added - ISA_DMA_API.  Set when we have functional
      enable_dma()/set_dma_mode()/etc.  set of helpers.  Next patches in the
      series will add missing dependencies for drivers that need them.
      
      I'm very carefully staying the hell out of the recurring flamefest on
      what exactly CONFIG_ISA would mean in ideal world - added symbol has a
      well-defined meaning and for now I really want to treat it as completely
      independent from the mess around CONFIG_ISA.

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds 提交于
      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
