[IA64] MCA recovery: Montecito support
The information in MCA records is filled in slightly differently on
Montecito than on Madison/McKinley. Usually, the cache check and bus
check target identifiers have the same address. On Montecito the
cache check and bus check target identifiers can be different if
a corrected error (ie SBE or unconsumed poison data) was encountered and
then an uncorrected error (ie DBE) was consumed. In that case, the
cache check target identifier is the physical address of the DBE (that
caused the MCA to surface) while the bus check target identifier is the
physical address of the SBE. This patch correctly finds the target
identifier that triggered the MCA.
If there are multiple valid cache target identifiers in the same
error record then use the one with the lowest cache level.

[MIPS] Fixup migration to GENERIC_TIME
Since we already moved to GENERIC_TIME, we should implement alternatives
of old do_gettimeoffset routines to get sub-jiffies resolution from
gettimeofday(). This patch includes:
* MIPS clocksource support (based on works by Manish Lachwani).
* remove unused gettimeoffset routines and related codes.
* remove unised 64bit do_div64_32().
* simplify mips_hpt_init. (no argument needed, __init tag)
* simplify c0_hpt_timer_init. (no need to write to c0_count)
* remove some hpt_init routines.
* mips_hpt_mask variable to specify bitmask of hpt value.
* convert jmr3927_do_gettimeoffset to jmr3927_hpt_read.
* convert ip27_do_gettimeoffset to ip27_hpt_read.
* convert bcm1480_do_gettimeoffset to bcm1480_hpt_read.
* simplify sb1250 hpt functions. (no need to subtract and shift)
In very rare circumstances would we be pruning a merged request and at
the same time delete the implicated cfqq from the rr_list, and not readd
it when the merged request got added. This could cause io stalls until
that process issued io again.
Fix it up by putting the rr_list add handling into cfq_add_rq_rb(),
identical to how pruning is handled in cfq_del_rq_rb(). This fixes a
hang reproducible with fsx-linux.

Add some comments about requirements for ubd_io_lock and expand its use.
When an irq signals that the "controller" (i.e. another thread on the host,
which does the actual requests and is the only one blocked on I/O on the host)
has done some work, we call again the request function ourselves
(do_ubd_request).
We now do that with ubd_io_lock held - that's useful to protect against
concurrent calls to elv_next_request and so on.
XXX: Maybe we shouldn't call at all the request function. Input needed on
this. Are we supposed to plug and unplug the queue? That code "indirectly"
does that by setting a flag, called do_ubd, which makes the request function
return (it's a residual of 2.4 block layer interface).
Meanwhile, however, merge this patch, which improves things.

It just so happens that Xen creates fragmented packets more often

[MIPS] Ocelot G: Fix build error and numerous warnings.
The cause of the build errors was a 64-bit kernel being configured in
ocelot_g_defconfig without the code being 64-bit proof. Fixed for now
by limiting 64-bit selection to SYS_SUPPORTS_64BIT_KERNEL if BROKEN.

[PATCH] fix i386 regparm=3 RT signal handlers on x86_64
The recent change to make x86_64 support i386 binaries compiled
with -mregparm=3 only covered signal handlers without SA_SIGINFO.
(the 3-arg "real-time" ones) This is useful for klibc at least.

[PATCH] sunrpc: fix refcounting problems in rpc servers
A recent patch fixed a problem which would occur when the refcount on an
auth_domain reached zero. This problem has not been reported in practice
despite existing in two major kernel releases because the refcount can
never reach zero.
This patch fixes the problems that stop the refcount reaching zero.
1/ We were adding to the refcount when inserting in the hash table,
but only removing from the hashtable when the refcount reached zero.
Obviously it never would. So don't count the implied reference of
being in the hash table.
2/ There are two paths on which a socket can be destroyed. One called
svcauth_unix_info_release(). The other didn't. So when the other was
taken, we can lose a reference to an ip_map which in-turn holds a
reference to an auth_domain
So unify the exit paths into svc_sock_put. This highlights the fact
that svc_delete_socket has slightly odd semantics - it does not drop
a reference but probably should. Fixing this need a bit more
thought and testing.

[PATCH] uml: fix compilation options for USER_OBJS
From: Jeff Dike <jdike@addtoit.com>, Paolo Giarrusso <blaisorblade@yahoo.it>
Make sure that when compiling USER_OBJS the correct compilation options are
passed; since they are compiled with USER_CFLAGS which is derived from
CFLAGS, make sure it is a recursively evaluated variable, so that changes
to CFLAGS done afterwards the inclusion of arch/$(ARCH)/Makefile are
reflected in USER_CFLAGS.
For instance, without this patch userspace objects are never compiled with
debug info active.

[PATCH] Fix "Remove the use of _syscallX macros in UML"
Fix commit 5f4c6bc1f369f20807a8e753c2308d1629478c61: it spits out warnings
about missing syscall prototype (it is in <unistd.h>) and it does not
recognize that two uses of _syscallX are to be resolved against kernel
headers in the source tree, not against _syscallX; they in fact do not
compile and would not work anyway.
If _syscallX macros will be removed from the kernel tree altogether, the
only reasonable solution for that piece of code is switching to open-coded
inline assembly (it's remapping the whole executable from memory, except
the page containing this code).
