* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus:
[MIPS] User stack pointer randomisation
[MIPS] Remove unused include/asm-mips/gfx.h
[MIPS] Remove unused include/asm-mips/ds1216.h
[MIPS] Workaround for RM7000 WAIT instruction aka erratum 38
[MIPS] Make support for weakly ordered LL/SC a config option.
[MIPS] Disable UserLocal runtime detection on platforms which never have it.
[MIPS] Disable MT runtime detection on platforms which never support MT.
Make it possible to use __start_notes and __stop_notes without getting a GPREL
overflow error from the FRV linker.
Small variables that would otherwise be in .data or .bss may, depending on the
arch, be placed in special sections (.sdata or .sbss) that permit single
instruction references on fixed instruction width machines.
__start_notes and __stop_notes aren't really char variables, and certainly
don't refer to data in .data or .bss. Making them type "void" fools the
compiler into not assuming anything about them.

The same problem that was fixed for tpm_ascii_bios_measurements_open()
in commit 178554ae75 also occurs in
tpm_binary_bios measurements(). Thanks for noticing this Satyam!
I tested the attached patch to fix tpm_binary_bios_measurments as well.

Remove time_interpolator code (This is generic code, but
only user was ia64. It has been superseded by the
CONFIG_GENERIC_TIME code).

and scaling improvements.

The kvm mmu uses page->private on shadow page tables; so does slub, and
an oops result. Fix by allocating regular pages for shadows instead of
using slub.

Allow real-mode emulation of rdmsr and wrmsr. This allows smp Windows to
boot, presumably for its sipi trampoline.

The memory slot management functions were oriented against vcpu 0, where
they should be kvm-wide. This causes hangs starting X on guest smp.
Fix by making the functions (and resultant tail in the mmu) non-vcpu-specific.
Unfortunately this reduces the efficiency of the mmu object cache a bit. We
may have to revisit this later.

We need to distinguish between large page shadows which have the nx bit set
and those which don't. The problem shows up when booting a newer smp Linux
kernel, where the trampoline page (which is in real mode, which uses the
same shadow pages as large pages) is using the same mapping as a kernel data
page, which is mapped using nx, causing kvm to spin on that page.

The controller has a bit indicating that one of the higher bits (the
error bits) are set. A previous bug caused this bit to be masked, but
since that bug has been fixed we have to clear it explicictly.

If add_to_page_cache_lru() fails, the page will not be locked. But
splice jumps to an error path that does a page release and unlock,
causing a BUG() in unlock_page().
Fix this by adding one more label that just releases the page. This bug
was actually triggered on EL5 by gurudas pai <gurudas.pai@oracle.com>
using fio.
