         several adjustments:
            a) additions to the systems list and cleanup of same
            b) change limits of NR_CPUS and make dep. on platform
      
         Note that MARVEL support is limited to 32 CPUs whan using
         42-bit KSEG - one needs 48-bit KSEG to handle up to 64, and
         we've never supported 48-bit KSEG.

      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.

      [PATCH] LOG2: Implement a general integer log2 facility in the kernel · f0d1b0b3
      David Howells 提交于
      This facility provides three entry points:
      
      	ilog2()		Log base 2 of unsigned long
      	ilog2_u32()	Log base 2 of u32
      	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.

      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.
