c7f6fa4411 x86, mce: don't log boot MCEs on Pentium M (model == 13) CPUs
On my legacy Pentium M laptop (Acer Extensa 2900) I get bogus MCE on a cold
boot with CONFIG_X86_NEW_MCE enabled, i.e. (after decoding it with mcelog):

MCE 0
HARDWARE ERROR. This is *NOT* a software problem!
Please contact your hardware vendor
CPU 0 BANK 1 MCG status:
MCi status:
Error overflow
Uncorrected error
Error enabled
Processor context corrupt
MCA: Data CACHE Level-1 UNKNOWN Error
STATUS f200000000000195 MCGSTATUS 0

[ The other STATUS values observed: f2000000000001b5 (... UNKNOWN error)
  and f200000000000115 (... READ Error).

  To verify that this is not a CONFIG_X86_NEW_MCE bug I also modified
  the CONFIG_X86_OLD_MCE code (which doesn't log any MCEs) to dump
  content of STATUS MSR before it is cleared during initialization. ]

Since the bogus MCE results in a kernel taint (which in turn disables
lockdep support) don't log boot MCEs on Pentium M (model == 13) CPUs
by default ("mce=bootlog" boot parameter can be be used to get the old
behavior).

baa28e3530 ARM: Show FIQ in /proc/interrupts on CONFIG_FIQ
The show_fiq_list() call in arch/arm/kernel/irq.c currently depends on
CONFIG_ARCH_ACORN, but this is not the only architecture that supports
the usage of FIQ. Change to calling this if CONFIG_FIQ is set (which
is what arch/arm/kernel/fiq.c is built by).

db616eb676 ARM: S3C: Add S3C_DEV_NAND Kconfig entry
Currently the S5PC100 does not define S3C_PA_NAND, leaving the NAND device
definitions in arch/arm/plat-s3c/dev-nand.c unbuildable. Add a KConfig
entry to select whether this is built.

As backwards compatibility, both the S3C24XX and S3C64XX define the new
configuration in their main Kconfig files until better support for basing
this selection on a per-machine basis can be sorted out.

S5PC100 is a new SoC with ARM coretex-A8 and numerous peripherals. This SoC is
successor of S3C64XX. S5PC100 has peripherals which are still similar to S3C
families so some drivers in "arch/arm/plat-s3c" can be shared. S5PC100 specific
drivers will be added in "arch/arm/plat-s5pcxx" or "arch/arm/mach-s5pc100"

The function uv_acpi_madt_oem_check() has been marked __init,
the struct apic_x2apic_uv_x has been marked __refdata.

cd7246f0e2 sh: Add support for DWARF GNU extensions
Also, remove the "fix" to DW_CFA_def_cfa_register where we reset the
frame's cfa_offset to 0. This action is incorrect when handling
DW_CFA_def_cfa_register as the DWARF spec specifically states that the
previous contents of cfa_offset should be used with the new
register. The reason that I thought cfa_offset should be reset to 0 was
because it was being assigned a bogus value prior to executing the
DW_CFA_def_cfa_register op. It turns out that the bogus cfa_offset value
came from interpreting .cfi_escape pseudo-ops (those used by the GNU
extensions) as CFA_DW_def_cfa ops.

b955873bf5 sh: Try again at getting the initial return address for an unwind
The previous hack for calculating the return address for the first frame
we unwind (dwarf_unwinder_dump) didn't always work. The problem was that
it assumed once it read the rule for calculating the return address,
there would be no new rules for calculating it. This isn't true because
the way in which the CFA is calculated can change as you progress
through a function and the return address is figured out using the
CFA. Therefore, the way to calculate the return address can change.

So, instead of using some offset from the beginning of
dwarf_unwind_stack which is just a flakey approach, and instead of
executing instructions from the FDE until the return address is setup,
we now figure out the pc in dwarf_unwind_stack() just before we call
dwarf_cfa_execute_insns().
