      m68knommu: make sure 2nd FEC eth interface pins are enabled on 5275 ColdFire · 938ed250
      Greg Ungerer 提交于
      The CONFIG_FEC2 define was removed from the kernel many versions ago.
      But it is still being used to set the multi-function pins when compiling
      for a ColdFire 527[45] SoC that has 2 ethernet interfaces. Remove the
      last remaining uses of this define, and so fix the setting of the pins
      for the 2nd ethernet interface.

      m68knommu: fix id number for second eth device on 5275 ColdFire · bfdd769a
      Greg Ungerer 提交于
      The second ColdFire FEC ethernet device should have an id number of 1,
      not 0. Otherwise it clashes with the first FEC ethernet device.
      
      On booting a kernel on a 5275 based board you will get messages out of
      the kernel like this:
      
          <4>------------[ cut here ]------------
          <4>WARNING: at fs/sysfs/dir.c:508 0x0a8b50()
          <4>sysfs: cannot create duplicate filename 'fec.0'
      
      And likely you won't be able to completely boot up after this at all.

      m68knommu: move and fix the 68VZ328 platform bootlogo.h · 89d78601
      Greg Ungerer 提交于
      The 68EZ328/bootlogo.h is not actually used in the 68EZ328 platform code
      at all. It is used by the 68VZ328 platform code though, so move it to be
      with the rest of the 68VZ328 platform code.
      
      Commit c0e0c89c ("fix broken boot logo
      inclusion") modified the bootlogo code to not be included in asm code.
      Modify 68VZ328/bootlogo.h so that the bootlogo bit map is named correctly
      for direct use in the C code.

      x86-32: fix up strncpy_from_user() sign error · 12e993b8
      Linus Torvalds 提交于
      The 'max' range needs to be unsigned, since the size of the user address
      space is bigger than 2GB.
      
      We know that 'count' is positive in 'long' (that is checked in the
      caller), so we will truncate 'max' down to something that fits in a
      signed long, but before we actually do that, that comparison needs to be
      done in unsigned.
      
      Bug introduced in commit 92ae03f2 ("x86: merge 32/64-bit versions of
      'strncpy_from_user()' and speed it up").  On x86-64 you can't trigger
      this, since the user address space is much smaller than 63 bits, and on
      x86-32 it works in practice, since you would seldom hit the strncpy
      limits anyway.
      
      I had actually tested the corner-cases, I had only tested them on
      x86-64.  Besides, I had only worried about the case of a pointer *close*
      to the end of the address space, rather than really far away from it ;)
      
      This also changes the "we hit the user-specified maximum" to return
      'res', for the trivial reason that gcc seems to generate better code
      that way.  'res' and 'count' are the same in that case, so it really
      doesn't matter which one we return.

      ARM: 7384/1: ThumbEE: Disable userspace TEEHBR access for !CONFIG_ARM_THUMBEE · 078c0454
      Jonathan Austin 提交于
      Currently when ThumbEE is not enabled (!CONFIG_ARM_THUMBEE) the ThumbEE
      register states are not saved/restored at context switch. The default state
      of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the
      ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour
      when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing
      covert communication - eg between userspace tasks running inside chroot
      jails.
      
      This patch sets up TEECR in order to prevent user-space access to TEEHBR
      when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to
      access TEEHBR.

      ARM: 7382/1: mm: truncate memory banks to fit in 4GB space for classic MMU · e5ab8580

      If a bank of memory spanning the 4GB boundary is added on a !CONFIG_LPAE

      have wrapped around to zero.

      ARM: 7359/2: smp_twd: Only wait for reprogramming on active cpus · 9f855503
      Linus Walleij 提交于
      During booting of cpu1, there is a short window where cpu1
      is online, but not active where cpu1 is occupied by waiting
      to become active. If cpu0 then decides to schedule something
      on cpu1 and wait for it to complete, before cpu0 has set
      cpu1 active, we have a deadlock.
      
      Typically it's this CPU frequency transition that happens at
      this time, so let's just not wait for it to happen, it will
      happen whenever the CPU eventually comes online instead.

      PCI: Fix regression in pci_restore_state(), v3 · ebfc5b80
      Rafael J. Wysocki 提交于
      Commit 26f41062 ("PCI: check for pci bar restore completion and
      retry") attempted to address problems with PCI BAR restoration on
      systems where FLR had not been completed before pci_restore_state() was
      called, but it did that in an utterly wrong way.
      
      First off, instead of retrying the writes for the BAR registers only, it
      did that for all of the PCI config space of the device, including the
      status register (whose value after the write quite obviously need not be
      the same as the written one).  Second, it added arbitrary delay to
      pci_restore_state() even for systems where the PCI config space
      restoration was successful at first attempt.  Finally, the mdelay(10) it
      added to every iteration of the writing loop was way too much of a delay
      for any reasonable device.
      
      All of this actually caused resume failures for some devices on Mikko's
      system.
      
      To fix the regression, make pci_restore_state() only retry the writes
      for BAR registers and only wait if the first read from the register
      doesn't return the written value.  Additionaly, make it wait for 1 ms,
      instead of 10 ms, after every failing attempt to write into config
      space.
