b160091802 x86: Remove "x86 CPU features in debugfs" (CONFIG_X86_CPU_DEBUG)
CONFIG_X86_CPU_DEBUG, which provides some parsed versions of the x86
CPU configuration via debugfs, has caused boot failures on real
hardware.  The value of this feature has been marginal at best, as all
this information is already available to userspace via generic
interfaces.

Causes crashes that have not been fixed + minimal utility -> remove.

See the referenced LKML thread for more information.

3b2e3d85ae Revert "x86: ucode-amd: Load ucode-patches once ..."
Commit d1c84f79a6
leads to a regression when microcode_amd.c is compiled into the kernel.
It causes a big boot delay because the firmware is not available.
See http://marc.info/?l=linux-kernel&m=126267290920060

It also renders the reload sysfs attribute useless.
Fixing this is too intrusive for an -rc5 kernel.

Thus I'd like to restore the microcode loading behaviour of kernel
2.6.32.

Original problem report from Mark Hounschell

3a5fc0e40c x86: Set hotpluggable nodes in nodes_possible_map
nodes_possible_map does not currently include nodes that have SRAT
entries that are all ACPI_SRAT_MEM_HOT_PLUGGABLE since the bit is
cleared in nodes_parsed if it does not have an online address range.

Unequivocally setting the bit in nodes_parsed is insufficient since
existing code, such as acpi_get_nodes(), assumes all nodes in the map
have online address ranges.  In fact, all code using nodes_parsed
assumes such nodes represent an address range of online memory.

nodes_possible_map is created by unioning nodes_parsed and
cpu_nodes_parsed; the former represents nodes with online memory and
the latter represents memoryless nodes.  We now set the bit for
hotpluggable nodes in cpu_nodes_parsed so that it also gets set in
nodes_possible_map.

[ hpa: Haicheng Li points out that this makes the naming of the
  variable cpu_nodes_parsed somewhat counterintuitive.  However, leave
  it as is in the interest of keeping the pure bug fix patch small. ]

1f667c690b ARM: 5886/1: arm: Fix cpu_proc_fin() for proc-v7.S and make kexec work
The comments in arm_machine_restart() suggest that cpu_proc_fin()
will clean and disable cache and turn off interrupts. This does
not seem to be implemented for proc-v7.S, implement it the same
way as for proc-v6.S.

This also makes kexec work for v7. Note that a related TLB and
branch traget flush patch is also needed to avoid kexec
"crc error".

Note that there are still some issues that seem to be related
to L2 cache being on and causing occasional uncompress "crc error"
with kexec. Anyways, this gets kexec mostly working on V7 for now.

79f211b8e1 sh64: wire up sys_accept4.
sh64 on the other hand provides both direct broken out syscalls as well
as socketcall access. As there are binaries that use both socketcall has
to stay around. The current ABI prefers direct syscalls.

It was pointed out that when sys_recvmmsg was added in, sys_accept4 was
overlooked. This takes care of wiring it up.

bb668da6d6 x86, apic: use logical flat for systems with <= 8 logical cpus
We can use logical flat mode if there are <= 8 logical cpu's
(irrespective of physical apic id values).  This will enable simplified
and efficient IPI and device interrupt routing on such platforms.

This has been tested to work on both Intel and AMD platforms.
Exceptions like IBM summit platform which can't use logical flat mode
are addressed by using OEM platform checks.

Chris McDermott from IBM confirmed that hurricane chipset in IBM summit
platforms doesn't support logical flat mode.  Irrespective of the other
things like apic_id's, total number of logical cpu's, Linux kernel
should default to physical mode for this system.

The 32-bit kernel does so using the OEM checks for the IBM summit
platform.  Add a similar OEM platform check for the 64bit kernel too.

Otherwise the linux kernel boot can hang on this platform under certain
bios/platform settings.

Fix this by removing the define of flush() in misc.c for

and that is being included unconditionally.

Also use a static inline function instead of define
for mach-mxc and mach-gemini to avoid similar bug

355e8e8d1b m68knommu: fix invalid flags on coldfire pit clocksource
The m68knommu coldfire pit clocksource looks like it was incorrectly
marked as a continuous clocksource.  Running with it marked as a
continuous clocksource could cause hangs when the system switches to
highres mode or enables nohz.

This patch removes the CLOCK_SOURCE_IS_CONTINUOUS flag on the coldfire pit
clocksource.  This will disallow systems using this clocksource from
entering oneshot mode (disabling highres timers and nohz).
