Commit 58b7983d15a422d9616bdc4e245d5c31dfaefbe2 intended to remove the
xfs "Makefile-linux-2.6" file, but it was mistakenly still left in the
tree as a empty file, and would cause git to correctly complain about a
tracked file being removed after a "make distclean" (which removes empty
files as garbage).
And the asm-x86/desc_64.h file was supposed to be removed by commit
c81c6ca45a69478c7877b729af1942d2b80ef582, but instead stayed around
containing just a single newline.
Get rid of them both properly.

Make the kernel jump into gdbstub (if configured) on a BUG with the register
set from the BUG rather than interpolating another illegal instruction and
leaving gdbstub's idea of the process counter in unsupported_syscall() where
the original BUG was detected.
With this patch, gdbstub reports a SIGABRT to the compiler and reports the
program counter at the original BUG, allowing the execution state at the time
of the BUG to be examined with GDB.

On many chipsets, the checks for DPLL enable or VGA mode will prevent the pipeconf regs from being restored, which could result in a blank display or X failing to come back after resume. So restore them unconditionally along with actually restoring pipe B's palette correctly.

On resume, if the interrupt state isn't restored correctly, we may end
up with a flood of unexpected or ill-timed interrupts, which could cause

When mthca_fmr_alloc() returns an error, it should free the MPT at the
index key, not mr->ibmr.lkey, since the lkey has been mangled by
hw_index_to_key() and no longer is the real index. This bug causes
corruption of the MPT table free bitmap when mthca_fmr_alloc() fails.

Commit efcd9971 ("IPoIB/cm: Factor out ipoib_cm_free_rx_reap_list()")
introduced a bug in ipoib_cm_dev_stop() when the receive drain times
out. In that case, the function moves all the pending rx stuff into a
private list but then calls ipoib_cm_free_rx_reap_list(), which
handles a different list.
Fix this by moving everything to the rx_reap_list that will actually
get freed up.
This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=906>.

This reverts commit 1f84260c8ce3b1ce26d4c1d6dedc2f33a3a29c0c, which is
suspected to be the reason for some very occasional and hard-to-trigger
crashes that usually look related to memory allocation (mostly reported
in networking, but since that's generally the most common source of
shortlived allocations - and allocations in interrupt contexts - that in
itself is not a big clue).
See for example
http://bugzilla.kernel.org/show_bug.cgi?id=9973
http://lkml.org/lkml/2008/2/19/278
etc.
One promising suspicion for what the root cause of bug is (which also
explains why it's so hard to trigger in practice) came from Eric
Dumazet:
"I wonder how SLUB_FASTPATH is supposed to work, since it is affected
by a classical ABA problem of lockless algo.
cmpxchg_local(&c->freelist, object, object[c->offset]) can succeed,
while an interrupt came (on this cpu), and several allocations were
done, and one free was performed at the end of this interruption, so
'object' was recycled.
c->freelist can then contain the previous value (object), but
object[c->offset] was changed by IRQ.
We then put back in freelist an already allocated object."
but another reason for the revert is simply that everybody agrees that
this code was the main suspect just by virtue of the pattern of oopses.

So far flush_cache_range() did't consider the I-cache largely because it
did rarely ever matter to real world code. This was working primarily
because normally code and data are don't share the same pages - with the
exception of MIPS16 code which uses address constants embedded between
the code. The following sequence of events may break the code:
o MIPS16 executable being loaded
o dynamic linker relocates the address constants embedded into the code:
o Uses mprotect(2) to make code pages PROT_READ|PROT_WRITE
o Performs the actual relocations by writing to the pages which likely
are COW. Because no PROT_EXEC is set I-cache coherence will not be
considered.
o Uses mprotect(2) to switch code pages back to PROT_READ|PROT_EXEC.
This results in a call to flush_cache_range() which also does not
consider I-caches.
o => executing the page just having been relocated may now result in the
I-cache getting refilled with stale data from memory.
