The existing MCE code calls flush_tlb hook with IS=0 (single page) resulting
partial invalidation of TLBs which is not right. This patch fixes that
by passing IS=0xc00 to invalidate whole TLB for successful recovery from
TLB and ERAT errors.

The MPIC message include should be done in the SoC file -- it's not
board-specific.
For some reason I don't see this dtsi being included by anything
currently.

The attach_adapter mechanism of the I2C framework is deprecated for years.
There are two users left, drivers for old Macintosh computers. I recently got
the idea of replacing this mechanism with a custom one with the help of
deferred probing. Because I don't have the hardware, I worked on a seperat

If a PTE or PMD is already marked NUMA when scanning to mark entries
for NUMA hinting then it is not necessary to update the entry and
incur a TLB flush penalty. Avoid the avoidhead where possible.

pte_protnone_numa is only safe to use after VMA checks for PROT_NONE are
complete. Treating a real PROT_NONE PTE as a NUMA hinting fault is going
to result in strangeness so add a check for it. BUG_ON looks like overkill
but if this is hit then it's a serious bug that could result in corruption
so
Commit b38af4721f59 ("x86,mm: fix pte_special versus pte_numa") adjusted
the pte_special check to take into account that a special pte had SPECIAL
and neither PRESENT nor PROTNONE. Now that NUMA hinting PTEs are no
longer modifying _PAGE_PRESENT it should be safe to restore the original
pte_special
Faults on the huge zero page are pointless and there is a BUG_ON
to catch them during fault time. This patch reintroduces a check
that avoids marking the zero page PAGE_NONE.

This patch removes the NUMA PTE bits and associated helpers. As a side-effect
it increases the maximum possible swap space on x86-64.
One potential source of problems is races between the marking of PTEs

With PROT_NONE, the traditional page table manipulation functions are

A transhuge NUMA hinting fault may find the page is migrating and should
wait until migration completes. The check is race-prone because the pmd
is deferenced outside of the page lock and while the race is tiny, it'll
be larger if the PMD is cleared while marking PMDs for hinting fault.

There are no functional changes here and I kept the mmotm-20141119 baseline
as that is what got tested but it rebases cleanly to current mmotm. The
series makes architectural changes but splitting this on a per-arch basis
would cause bisect-related brain damage. I'm hoping this can go through

Add support for the Artesyn MVME2500 Single Board Computer.
The MVME2500 is a 6U form factor VME64 computer with:
- A single Freescale QorIQ P2010 CPU
- 1 GB of DDR3 onboard memory
- Three Gigabit Ethernets
- Five 16550 compatible UARTS
- One USB 2.0 port,
Fix the GPIO address in the device tree to match the documented location.
