RDMA/cma: Allow early transition to RTS to handle lost CM messages
During connection establishment, the passive side of a connection can
receive messages from the active side before the connection event has
been delivered to the user. Allow the passive side to send messages
in response to received data before the event is delivered. To handle
the case where the connection messages are lost, a new rdma_notify()

IB/fmr: ib_flush_fmr_pool() may wait too long
ib_flush_fmr_pool() stashes away the request generation number
properly, but then goes ahead and rereads it every time it tests
whether the flush generation number has caught up. This means that
there is a theoretical possibility of livelock, if the request
generation number keeps getting bumped and the flush generation number
never catches up. The fix is simple: use the request generation
number read at the beginning of the function.
Also, atomic_inc() followed by atomic_read() can be replaced with
atomic_int_return(). There's no real requirement for atomicity here
but we might as well shrink the code.

[IA64] fix possible XPC deadlock when disconnecting
This patch eliminates a potential deadlock that is possible when XPC
disconnects a channel to a partition that has gone down. This deadlock will
occur if at least one of the kthreads created by XPC for the purpose of making
callouts to the channel's registerer is detained in the registerer and will
not be returning back to XPC until some registerer request occurs on the now
downed partition. The potential for a deadlock is removed by ensuring that
there always is a kthread available to make the channel disconnecting callout

[IA64] - Reduce overhead of FP exception logging messages
Improve the scalability of the fpswa code that rate-limits
logging of messages.
There are 2 distinctly different problems in this code.
1) If prctl is used to disable logging, last_time is never
updated. The result is that fpu_swa_count is zeroed out on
EVERY fp fault. This causes a very very hot cache line.
The fix reduces the wallclock time of a 1024p FP exception test
from 28734 sec to 19 sec!!!
2) On VERY large systems, excessive messages are logged because
multiple cpus can each reset or increment fpu_swa_count at
about the same time. The result is that hundreds of messages
are logged each second. The fixes reduces the logging rate
to ~1 per second.

better store the whole register values.

[MIPS] Discard .exit.text and .exit.data at runtime.
While the recent cset
86384d544157db23879064cde36061cdcafc6794 did improve
things it didn't resolve all the problems. So bite the bullet and discard
.exit.text and .exit.data at runtime. Which of course sucks because it
bloats binaries with code that will never ever be used but it's the only
thing that will work reliable as demonstrated by the function sd_major() in
drivers/scsi/sd.c.
Gcc may compile sd_major() using a jump table which it will put into
.rodata. If it also inlines sd_major's function body into exit_sd() which
gcc > 3.4.x does. If CONFIG_BLK_DEV_SD has been set to y we would like ld
to discard exit_sd's code at link time. However sd_major happens to
contain a switch statement which gcc will compile using a jump table in
.rodata on the architectures I checked. So, when ld later discards
.exit.text only the jump table in .rodata with its stale references to
the discard .exit.text will be left which any no antique ld will honor
with a link error.

Normally networking isn't invoked with interrupts turned off, but I

Given that this is only used for printk, the easiest solution is probably

rtc: rtc-sh: alarm support.
This adds alarm support for the RTC_ALM_SET, RTC_ALM_READ,
RTC_WKALM_SET and RTC_WKALM_RD operations to rtc-sh.
The only unusual part is the handling of the alarm interrupt. If you
clear the alarm flag (AF) while the time in the RTC still matches the
time in the alarm registers than AF is immediately re-set, and if the
alarm interrupt (AIE) is still enabled then it re-triggers. I was
originally getting around 20k+ interrupts generated during the second
when the RTC and alarm registers matches.
The solution I've used is to clear AIE when the alarm goes off and
then use the carry interrupt to re-enabled it. The carry interrupt
will check AF and re-enabled AIE if it's clear. If AF is not clear
it'll clear it and then the check will be repeated next carry
interrupt. This a bit in rtc structure that indicates that it's
waiting to have AIE re-enabled so it doesn't turn it on when it
wasn't enabled anyway.

rtc: rtc-sh: fix rtc for out-by-one for the month.
The RMONCNT register, which holds the month in the RTC, takes a value
between 1 and 12 while the tm_mon field in the time structures takes
a value between 0 and 11. This wasn't being taken into account in
rtc-sh resulting in the month being out by one.
eg, on my board during boot the RTC is set to:
RTC is set to Thu Jul 01 09:00:00 1999
but "hwclock -r" immediately after logging in was showing:
Sun Aug 1 09:01:43 1999 0.000000 seconds
