b015124e56 [x86 setup] Volatilize asm() statements
asm() statements need to be volatile when:

a. They have side effects (other than value returned).
b. When the value returned can vary over time.
c. When they have ordering constraints that cannot be expressed to gcc.

In particular, the keyboard and timer reads were violating constraint (b),
which resulted in the keyboard/timeout poll getting
loop-invariant-removed when compiling with gcc 4.2.0.

Thanks to an anonymous bug reporter for pointing this out.

2aa44d0567 sched: sched_clock_idle_[sleep|wakeup]_event()
construct a more or less wall-clock time out of sched_clock(), by
using ACPI-idle's existing knowledge about how much time we spent
idling. This allows the rq clock to work around TSC-stops-in-C2,
TSC-gets-corrupted-in-C3 type of problems.

( Besides the scheduler's statistics this also benefits blktrace and
  printk-timestamps as well. )

Furthermore, the precise before-C2/C3-sleep and after-C2/C3-wakeup
callbacks allow the scheduler to get out the most of the period where
the CPU has a reliable TSC. This results in slightly more precise
task statistics.

the ACPI bits were acked by Len.

Xen i386 xen-head.S fix sections mixup

xen-head.S does not come back to the data section, leaving the text section
as current section. It causes problems with a slightly enhanced DEBUG_RODATA
that supports CONFIG_HOTPLUG and bringing a CPU up after the text has been
marked read-only: reference to early_gdt_descr causes a page fault.

Updates:

- It should be using pushsection/popsection.
- Actually, the push/popsections around the ELFNOTEs are redundant; ELFNOTE()
  does its own push/popsection to put things into the appropriate .note* section
  anyway.

f4768ffd1d uml: fix previous request size limit fix
The previous patch which limited the number of sectors in a single request
to a COWed device was correct in concept, but the limit was implemented in
the wrong place.

By putting it in ubd_add, it covered the cases where the COWing was
specified on the command line.  However, when the command line only has the
COW file specified, the fact that it's a COW file isn't known until it's
opened, so the limit is missed in these cases.

This patch moves the sector limit from ubd_add to ubd_open_dev.

9c5f225f1a [S390] kprobes: fix instruction length calculation
Placing a kprobe on "bc" instruction (s390/s390x) can cause an oops.
The instruction length is encoded into the first two bits of the s390
instruction. Kprobe is incorrectly computing the instruction length.
The instruction length is used for determining what type of "fix-up" is
needed for conditional branch instruction. The problem can bee seen by
placing a kprobe on a "bc" instruction that will not branch. The
results is that Kprobe incorrectly computes the new instruction
pointer (psw.addr) after single stepping the instruction. The problem
is corrected with this patch.

9b5a03e198 [S390] hypfs: inode corruption due to missing locking
hypfs removes the whole hypfs directory tree and creates a new one, when a
process triggers an update by writing to the "update" attribute. When removing
and creating files, it is necessary to lock the inode of the parent directory
where the files live. Currently hypfs does not lock the parent inode, which
can lead to inode corruption. This patch:
 * Introduces correct locking
 * Fixes i_nlink reference counting for inodes, when creating directories
 * Adds info printk, when hypfs filesystem has been mounted

da2f5f7bf4 sh: Fix DSP opcode regression for SH3-DSP parts.
Older versions of binutils do not support -Wa,-isa= tuning, which is
something we rely on for enabling DSP opcode support on the newer
parts. SH3-DSP parts can still be handled with -Wa,-dsp even if the
newer parts require the newer versions of binutils for supporting the
new opcodes.

This was broken in -rc1 when the SH4AL-DSP support was being reworked,
and is needed to get SH3-DSP working with older toolchains again.

	undefine disable_ioapic_setup() when it doesn't apply.

	delete undefinition of disable_ioapic_setup()

d34fda4a84 x86: properly initialize temp insn buffer for paravirt patching
With commit ab144f5ec6 the patching code
now collects the complete new instruction stream into a temp buffer
before finally patching in the new insns.  In some cases the paravirt
patchers will choose to leave the patch site unpatched (length mismatch,
clobbers mismatch, etc).

This causes the new patching code to copy an uninitialized temp buffer,
i.e.  garbage, to the callsite.  Simply make sure to always initialize
the buffer with the original instruction stream.  A better fix is to
audit all the patchers and return proper length so that apply_paravirt()
can skip copies when we leave the patch site untouched.

471e7a4484 [IA64] Enable early console for Ski simulator
When using Ski to debug early startup, it's a bit of a pain not to
have printk.

This patch enables the simulated console very early.
It may be worth conditionalising on the command line... but this is
enough for now.

b09e789c43 [IA64] forbid ptrace changes psr.ri to 3
The "ri" field in the processor status register only has defined
values of 0, 1, 2.  Do not let ptrace set this to 3.  As with
other reserved fields in registers we silently discard the value.

86d7a9a9c4 [POWERPC] Fix FSL BookE machine check reporting
Reserved MCSR bits on FSL BookE parts may have spurious values
when mcheck occurs.  Mask these off when printing the MCSR to
avoid confusion.  Also, get rid of the MCSR_GL_CI bit defined
for e500 - this bit doesn't actually have any meaning.

b66510cb99 [POWERPC] Fix interrupt routing and setup of ULI M1575 on FSL boards
The interrupt routing in the device trees for the ULI M1575 was
inproperly using the interrupt line field as pci function.  Fixed
up the device tree's to actual conform for to specification and
changed the interrupt mapping code so it just uses a static mapping
setup as follows:

PIRQA - IRQ9
PIRQB - IRQ10
PIRQC - IRQ11
PIRQD - IRQ12
USB 1.1 OCHI (1c.0) - IRQ12
USB 1.1 OCHI (1c.1) - IRQ9
USB 1.1 OCHI (1c.2) - IRQ10
USB 1.1 ECHI (1c.3) - IRQ11
LAN (1b.0) - IRQ6
AC97 (1d.0) - IRQ6
Modem (1d.1) - IRQ6
HD Audio (1d.2) - IRQ6
SATA (1f.1) - IRQ5
SMB (1e.1) - IRQ7
PMU (1e.2) - IRQ7
PATA (1f.0) - IRQ14/15

Took the oppurtunity to refactor the code into a single file so we
don't have to duplicate these fixes on the two current boards in the
tree and several forth coming boards that will also need the code.

Fixed RTC support that requires a dummy memory read on the P2P bridge
to unlock the RTC and setup the default of the RTC alarm registers to
match with a basic x86 style CMOS RTC.

Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure
the PCI IO space has been setup properly before we start poking ISA
registers at random locations.
