2006-12-12RDMA/cma: Remove unneeded qp_type parameter from rdma_cmSean Hefty
The qp_type parameter into the rdma_cm is unneeded, and can be misleading. The QP type should be determined from the port space. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-12-12IB/ipath: Fix IRQ for PCI Express HCAsRoland Dreier
Commit 51f65ebc ("IB/ipath - program intconfig register using new HT irq hook"), which fixed interrupts for HyperTransport HCAs, broke PCI Express HCAs, because for those HCAs, the driver uses the value of pdev->irq before pci_enable_msi() and ends up getting a totally bogus IRQ number. Fix this by using the value of pdev->irq after pci_enable_msi(). Signed-off-by: Roland Dreier <rolandd@cisco.com>

2006-12-12IB/fmr: ib_flush_fmr_pool() may wait too longRoland Dreier
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. This bug was discovered using David Binderman's list of "set but never used" warnings from icc.

2006-12-12[PATCH] remove config ordering/dependency between ucb1400-ts and sound subsystemNicolas Pitre
Commit 2d4ba4a3b9aef95d328d74a17ae84f8d658059e2 introduced a dependency that was never meant to exist when the ac97_bus.c module was created. Move ac97_bus.c up the directory hierarchy to make sure it is built when selected even if sound is configured out so things work as originally intended.

2006-12-12[PATCH] lockdep: fix seqlock_init()Ingo Molnar
seqlock_init() needs to use spin_lock_init() for dynamic locks, so that lockdep is notified about the presence of a new lock. (this is a fallout of the recent networking merge, which started using the so-far unused seqlock_init() API.) This fix solves the following lockdep-internal warning on current -git: INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator. __lock_acquire+0x10c/0x9f9 lock_acquire+0x56/0x72 _spin_lock+0x35/0x42 neigh_destroy+0x9d/0x12e neigh_periodic_timer+0x10a/0x15c run_timer_softirq+0x126/0x18e __do_softirq+0x6b/0xe6 do_softirq+0x64/0xd2 ksoftirqd+0x82/0x138 Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-12-12[PATCH] remove blk_queue_activity_fnBoaz Harrosh
While working on bidi support at struct request level I have found that blk_queue_activity_fn is actually never used. The only user is in ide-probe.c with this code: /* enable led activity for disk drives only */ if (drive->media == ide_disk && hwif->led_act) blk_queue_activity_fn(q, hwif->led_act, drive); And led_act is never initialized anywhere. (Looking back at older kernels it was used in the PPC arch, but was removed around 2.6.18) Unless it is all for future use off course.

2006-12-12[MIPS] Discard .exit.text and .exit.data at runtime.Ralf Baechle
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.

2006-12-12sh: BUG() handling through trapa vector.Paul Mundt
Previously we haven't been doing anything with verbose BUG() reporting, and we've been relying on the oops path for handling BUG()'s, which is rather sub-optimal. This switches BUG handling to use a fixed trapa vector (#0x3e) where we construct a small bug frame post trapa instruction to get the context right. This also makes it trivial to wire up a DIE_BUG for the atomic die chain, which we couldn't really do before. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-12rtc: rtc-sh: alarm support.Jamie Lenehan
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.

2006-12-12rtc: rtc-sh: fix rtc for out-by-one for the month.Jamie Lenehan
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 Signed-off-by: Jamie Lenehan <lenehan@twibble.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

We have a few different ways to do the atomic operations, so split them out in to different headers rather than bloating atomic.h. Kernelspace gUSA will take this up to a third implementation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
