410ab512e5 [IA64] efi.c Add /* never reached */ annotation
As written, this loop could be for (;;) instead of do while (md).  The tests
inside the loop always result in a return so the loop never terminates normally.

7d9aed26ed [IA64] Make efi.c mostly fit in 80 columns
This patch is purely whitespace changes to make the code fit in 80
columns, plus fix some inconsistent indentation.  The efi_guidcmp()
tests remain wider than 80-columns since that seems to be the most
clear.

34508f66b6 x86: AMD Athlon X2 hard hang fix
An Athlon 64 X2 test system showed hard hangs shortly after marking
the kernel text read-only, if we tried to preserve largepages and
changed the PSE entry from RW to RO. The pagetable code itself is
correct, it's the CPU that locked up hard (and not even the NMI
watchdog could punch through that hard hang).

So be conservative and always do splitups - like we did in the past.

626c2c9d06 x86: use the pfn from the page when change its attributes
When changing the attributes of a pte, we should use the PFN from the
existing PTE rather than going through hoops calculating what we think
it might have been; this is both fragile and totally unneeded. It also
makes it more hairy to call any of these functions on non-direct maps
for no good reason whatsover.

With this change, __change_page_attr() no longer takes a pfn as argument,
which simplifies all the callers.

cc0f21bbc1 x86: teach the static_protection function about high mappings
Right now, enforcing that the high mapping of the kernel text doesn't
get the NX bit is done deep in the guts of CPA, rather than in the
static_protection() function that enforces all other per-arch sanity
checks.

This patch moves this sanity check into the central static_protection()
function instead, and makes it apply ONLY to the kernel text, not to all
other areas in the high mapping.

f0be6c6a69 x86 setup: print missing CPU features in cleartext
Instead of obscure numbers, print the list of missing CPU features in
cleartext.  To conserve space, use a host program (mkcpustr.c) to
produce a compact list of mandatory features only.

fa1408e4df x86: unify CPU feature string names
Move the CPU feature string names to a separate file (common to 32
and 64 bits); additionally, make <asm/cpufeature.h> includable by host
code in preparation for including the CPU feature strings in the boot
code.
