Pull x86 linker bug workarounds from Peter Anvin.
GNU ld-2.22.52.0.[12] (*) has an unfortunate bug where it incorrectly
turns certain relocation entries absolute. Section-relative symbols
that are part of otherwise empty sections are silently changed them to
absolute. We rely on section-relative symbols staying section-relative,
and actually have several sections in the linker script solely for this
purpose.
See for example
http://sourceware.org/bugzilla/show_bug.cgi?id=14052
We could just black-list the buggy linker, but it appears that it got
shipped in at least F17, and possibly other distros too, so it's sadly
not some rare unusual case.
This backports the workaround from the x86/trampoline branch, and as
Peter says: "This is not a minimal fix, not at all, but it is a tested
code base."

When the relocs tool throws an error, let the error message say if it
is an absolute or relative symbol. This should make it a lot more

the reason if additional symbol bugs show up.

GNU ld 2.22.52.0.1 has a bug that it blindly changes symbols from
section-relative to absolute if they are in a section of zero length.
This turns the symbols __init_begin and __init_end into absolute

relative symbols.

A new option is added to the relocs tool called '--realmode'.
This option causes the generation of 16-bit segment relocations
and 32-bit linear relocations for the real-mode code. When
the real-mode code is moved to the low-memory during kernel
initialization, these relocation entries can be used to
relocate the code properly.
In the assembly code 16-bit segment relocations must be relative
to the 'real_mode_seg' absolute symbol. Linear relocations must be
relative to a symbol prefixed with 'pa_'.
16-bit segment relocation is used to load cs:ip in 16-bit code.
Linear relocations are used in the 32-bit code for relocatable
data references. They are declared in the linker script of the
real-mode code.
The relocs tool is moved to arch/x86/tools/relocs.c, and added new
target archscripts that can be used to build scripts needed building
an architecture. be compiled before building the arch/x86 tree.
[ hpa: accelerating this because it detects invalid absolute
relocations, a serious bug in binutils 2.22.52.0.x which currently
produces bad kernels. ]

Some discussion with the glibc mailing lists revealed that this was
necessary for 64-bit platforms with MIPS-like sign-extension rules
for 32-bit values. The original symptom was that passing (uid_t)-1 to
setreuid() was failing in programs linked -pthread because of the "setxid"
mechanism for passing setxid-type function arguments to the syscall code.
SYSCALL_WRAPPERS handles ensuring that all syscall arguments end up with
proper sign-extension and is thus the appropriate fix for this problem.
On other platforms (s390, powerpc, sparc64, and mips) this was fixed
in 2.6.28.6. The general issue is tracked as CVE-2009-0029.

Commit ff9a184c ("ARM: 7400/1: vfp: clear fpscr length and stride bits
on entry to sig handler") flushes the VFP state prior to entering a
signal handler so that a VFP operation inside the handler will trap and
force a restore of ABI-compliant registers. Reflushing and disabling VFP
on the sigreturn path is predicated on the saved thread state indicating
that VFP was used by the handler -- however for SMP platforms this is
only set on context-switch, making the check unreliable and causing VFP
register corruption in userspace since the register values are not
necessarily those restored from the sigframe.
This patch unconditionally flushes the VFP state after a signal handler.
Since we already perform the flush before the handler and the flushing
itself happens lazily, the redundant flush when VFP is not used by the
handler is essentially a nop.

A zero value for prot_sect in the memory types table implies that
section mappings should never be created for the memory type in question.
This is checked for in alloc_init_section().
With LPAE, we set a bit to mask access flag faults for kernel mappings.
This breaks the aforementioned (!prot_sect) check in alloc_init_section().
This patch fixes this bug by first checking for a non-zero
prot_sect before setting the PMD_SECT_AF flag.

First, we were at risk of handling thread-info flags, in particular
do_signal(), when returning from kernel space. This could happen
after a failed kernel_execve(), or when forking a kernel thread.
The fix is to test in do_work_pending() for user_mode() and return
immediately if so; we already had this test for one of the flags,
so I just hoisted it to the top of the function.
Second, if a ptraced process updated the callee-saved registers
in the ptregs struct and then processed another thread-info flag, we
would overwrite the modifications with the original callee-saved
registers. To fix this, we add a register to note if we've already
saved the registers once, and skip doing it on additional passes
through the loop. To avoid a performance hit from the couple of
extra instructions involved, I modified the GET_THREAD_INFO() macro
to be guaranteed to be one instruction, then bundled it with adjacent
instructions, yielding an overall net savings.

When handling the H_BULK_REMOVE hypercall, we were forgetting to
invalidate and unlock the hashed page table entry (HPTE) in the case
where the page had been paged out. This fixes it by clearing the
first doubleword of the HPTE in that case.
This fixes a regression introduced in commit a92bce95f0 ("KVM: PPC:
Book3S HV: Keep HPTE locked when invalidating"). The effect of the
regression is that the host kernel will sometimes hang when under

When jumping back into the kernel to code that knows that it would be
using HSRR registers instead of SRR registers, we need to make sure we
pass it all information on where to jump to in HSRR registers.
Unfortunately, we used r10 to store the information to distinguish between
the HSRR and SRR case. That register got clobbered in between though,
rendering the later comparison invalid.
Instead, let's use cr1 to store this information. That way we don't
need yet another register and everyone's happy.

When running on a system that is HV capable, some interrupts use HSRR
SPRs instead of the normal SRR SPRs. These are also used in the Linux
handlers to jump back to code after an interrupt got processed.
Unfortunately, in our "jump back to the real host handler after we've
done the context switch" code, we were only setting the SRR SPRs,
rendering Linux to jump back to some invalid IP after it's processed
the interrupt.
This fixes random crashes on p7 opal mode with PR KVM for me.

In addition to normal "priviledged instruction" traps, we can also receive
"emulation assist" traps on newer hardware that has the HV bit set.
Handle that one the same way as a privileged instruction, including the
instruction fetching. That way we don't execute old instructions that we
happen to still leave in that field when an emul assist trap comes.
This fixes -M mac99 / -M g3beige on p7 bare metal for me.

Pull ARM: SoC fixes from Olof Johansson:
"I was hoping to be done with fixes for 3.4 but we got two branches
from subarch maintainers the last couple of days. So here is one
last(?) pull request for arm-soc containing 7 patches:
- Five of them are for shmobile dealing with SMP setup and compile
failures
- The remaining two are for regressions on the Samsung platforms"

Commit 069d4e743 ("ARM: EXYNOS4: Remove clock event timers using
ARM private timers") removed support for local timers and forced
to use MCT as event source. However MCT is not operating properly
on early revision of EXYNOS4 SoCs. All UniversalC210 boards are
based on it, so that commit broke support for it. This patch
provides a workaround that enables UniversalC210 boards to boot
again. s5p-timer is used as an event source, it works only for
non-SMP builds.
