b621370a35 sh: sh7724 clock framework rewrite V3
This patch contains V3 of the sh7724 clock framework
rewrite. The new code makes use of the recently merged
div4, div6 and mstp32 helper code. Both extal and fll are
supported as input clocks to the pll. The div6 clocks are
fed through a divide-by-3 block.

0d4fdbb64f sh: rework mode pin code
This patch reworks the mode pin code to keep the pin
definitions in one place. The mode pins values are now
the value of the bit instead of bit number.

With this patch in place the sh7785 header file contains
mode pin comments. The sh7785 clock code and the sh7785lcr
board code are updated to reflect the new shared mode pins.

2693e2740d sh: clock div6 helper code
This patch adds div6 clock helper code. The div6 clocks
are simply 6-bit divide-by-n modules where n is 1 to 64.

Needed for vclk on sh7722, sh7723, sh7343 and sh7366.
sh7724 needs this even more for vclk, fclka, fclkb,
irdaclk and spuclk.

511b01bdf6 Revert "x86, bts: reenable ptrace branch trace support"
This reverts commit 7e0bfad24d.

A late objection to the ABI has arrived:

   http://lkml.org/lkml/2009/6/10/253

Keep the ABI disabled out of caution, to not create premature
user-space expectations.

While the hw-branch-tracing variant uses and tests the BTS code.

0fea615e52 CPUFREQ: Mark e_powersaver driver as EXPERIMENTAL and DANGEROUS
The e_powersaver driver for VIA's C7 CPU's needs to be marked as
DANGEROUS as it configures the CPU to power states that are out
of specification.

According to Centaur, all systems with C7 and Nano CPU's support
the ACPI p-state method.  Thus, the acpi-cpufreq driver should
be used instead.

The VIA/Centaur C7, C7-M and Nano CPU's all support ACPI based cpu p-states
using a MSR interface.  The Linux driver just never made use of it, since in
addition to the check for the EST flag it also checked if the vendor is Intel.

42937e81a8 x86: Detect use of extended APIC ID for AMD CPUs
Booting a 32-bit kernel on Magny-Cours results in the following panic:

  ...
  Using APIC driver default
  ...
  Overriding APIC driver with bigsmp
  ...
  Getting VERSION: 80050010
  Getting VERSION: 80050010

  Getting LVT0: 700
  Getting LVT1: 10000
  Kernel panic - not syncing: Boot APIC ID in local APIC unexpected (16 vs 0)
  Pid: 1, comm: swapper Not tainted 2.6.30-rcX #2
  Call Trace:
   [<c05194da>] ? panic+0x38/0xd3
   [<c0743102>] ? native_smp_prepare_cpus+0x259/0x31f

   [<c073b15f>] ? kernel_init+0x0/0x141
   [<c020325f>] ? kernel_thread_helper+0x7/0x10

The reason is that default_get_apic_id handled extension of local APIC
ID field just in case of XAPIC.

Thus for this AMD CPU, default_get_apic_id() returns 0 and
bigsmp_get_apic_id() returns 16 which leads to the respective kernel
panic.

This patch introduces a Linux specific feature flag to indicate
support for extended APIC id (8 bits instead of 4 bits width) and sets
the flag on AMD CPUs if applicable.

c9690998ef x86: memtest: remove 64-bit division
Using gcc 3.3.5 a "make allmodconfig" + "CONFIG_KVM=n"
triggers a build error:

 arch/x86/mm/built-in.o(.init.text+0x43f7): In function `__change_page_attr':
 arch/x86/mm/pageattr.c:114: undefined reference to `__udivdi3'
 make: *** [.tmp_vmlinux1] Error 1

The culprit turned out to be a division in arch/x86/mm/memtest.c
For more info see this thread:

  http://marc.info/?l=linux-kernel&m=124416232620683

The patch entirely removes the division that caused the build
error.

c4ed3f04ba x86, UV: Fix macros for multiple coherency domains
Fix bug in the SGI UV macros that support systems with multiple
coherency domains.  The macros used for referencing global MMR
(chipset registers) are failing to correctly "or" the NASID
(node identifier) bits that reside above M+N. These high bits
are supplied automatically by the chipset for memory accesses
coming from the processor socket.

However, the bits must be present for references to the special
global MMR space used to map chipset registers. (See uv_hub.h
for more details ...)

The bug results in references to invalid/incorrect nodes.

5636919b5c MIPS: Outline udelay and fix a few issues.
Outlining fixes the issue were on certain CPUs such as the R10000 family
the delay loop would need an extra cycle if it overlaps a cacheline
boundary.

The rewrite also fixes build errors with GCC 4.4 which was changed in
way incompatible with the kernel's inline assembly.

Relying on pure C for computation of the delay value removes the need for
explicit.  The price we pay is a slight slowdown of the computation - to
be fixed on another day.
