      [PATCH] powerpc: Add FSL SOC library and setup code · eed32001
      由 Kumar Gala 提交于 
      Parse the flat device tree for devices on Freescale SOC's that we know
about (gianfar, gianfar_mdio, i2c, mpc83xx_wdt).  We need to setup
platform devices and platform data for these devices to match arch/ppc
usage.

Also add a helper function (get_immrbase) that reports the base
address of the MMIO registers on the SOC.

      [PATCH] powerpc: Allow for ppc_md restart, power_off, and halt to be NULL · b8e383d5
      由 Kumar Gala 提交于 
      On a number of embedded reference boards there isn't always a
way to reset, power_off, or halt the board.  Rather than having
each board implement a spin loop just let the generic code do
it.

      [PATCH] powerpc: oprofile cpu type names clash with other code · 7a45fb19
      由 Andy Whitcroft 提交于 
      In 2.6.15-git6 a change was commited in the oprofile support in
the powerpc architecture.  It introduced the powerpc_oprofile_type
which contains the define G4.  This causes a name clash with the
existing wacom usb tablet driver.

      CC [M]  drivers/usb/input/wacom.o
    drivers/usb/input/wacom.c:98: error: conflicting types for `G4'
    include/asm/cputable.h:37: error: previous declaration of `G4'
      CC [M]  drivers/usb/mon/mon_text.o
    make[3]: *** [drivers/usb/input/wacom.o] Error 1
    make[2]: *** [drivers/usb/input] Error 2

The elements of an enum declared in global scope are effectivly
global identifiers themselves.  As such we need to ensure the names
are unique.  This patch updates the later oprofile support to use
unique names.

      powerpc: Provide a suitable AT_PLATFORM value · 80f15dc7
      由 Paul Mackerras 提交于 
      The glibc folks want to use AT_PLATFORM to select between possible
alternative versions of shared libraries.  This commit makes the kernel
supply an AT_PLATFORM string that indicates what class of processor
we are running on.  Processors with the same set of user-level
instructions and roughly the same instruction scheduling characteristics
are given the same AT_PLATFORM value; for example, 821, 823 and 860
are all reported as "ppc823", and 7447, 7447A, 7448, 7450, 7451, 7455
are all called "ppc7450".

The intention is that the AT_PLATFORM values match the values that
gcc accepts for the -mcpu= option.  For values which are numeric
(e.g. -mcpu=750), "ppc" has been prepended.

This also adds a PPC_FEATURE_BOOKE bit to the AT_HWCAP value and sets
it for the 440 family and the Freescale 85xx family.

      [PATCH] Increase AT_VECTOR_SIZE · 67daf5f1
      由 Paul Mackerras 提交于 
      On PowerPC, we want to be able to provide an AT_PLATFORM aux table
entry to userspace, so that glibc can choose optimized libraries for
the processor we're running on.  Unfortunately that would be the 21st
aux table entry on powerpc, meaning that the aux table including the
terminating null entry would overflow the mm->saved_auxv[] array,
leading to userland programs segfaulting.

This increases the size of the mm->saved_auxv array to be large enough
to accommodate an AT_PLATFORM entry on powerpc.

      [PATCH] Fix oops in ufs_fill_super at mount time · 8a430d74
      由 Evgeniy 提交于 
      There's a lack of parenthesis in fs/ufs/utils.h, so instead of the 512th
byte of buffer, the usb2 pointer will point to the nth structure of type
ufs_super_block_second.

This can cause a mount-time oops if you're unlucky (especially with
DEBUG_PAGEALLOC, which is how Alexey Dobriyan saw this problem)
