Due to a merge conflict, the sched_relax_domain_level control file was marked as being handled by cpuset_read/write_u64, but the code to handle it was actually in cpuset_common_file_read/write. Since the value being written/read is in fact a signed integer, it should be treated as such; this patch adds cpuset_read/write_s64 functions, and uses them to handle the sched_relax_domain_level file. With this patch, the sched_relax_domain_level can be read and written, and the correct contents seen/updated.

For e.g. proper TTY canonical support, IUTF8 termios flag has to be set as appropriate. Linux used to not care about setting that flag for VT TTYs.

We clobber %i1 as well as %i0 for these system calls, because they give two return values. Therefore, on error, we have to restore %i1 properly or else the restart explodes since it uses the wrong arguments. This fixes glibc's nptl/tst-eintr1.c testcase. Signed-off-by: NDavid S.

What's fixed: in ipath_cancel_sends() We need to unconditionally set ABORTING. So, swap the tests so the set_bit() isn't shadowed by the &&. If we've disarmed the piobufs, then we need to unconditionally set DISARMED. So, move it out from the overly protective if at the bottom. in sdma_abort_task() Abort_task was written knowing that the SDMA engine would always be reset (and restarted) on error. A recent change broke that fundamental assumption by taking the restart portion and making it conditional on a link status change. But, SDMA can go boom without a link status change in some conditions. Signed-off-by: NJohn Gregor <john.gregor@qlogic.com> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Now that we always use PIO for vl15 on 7220, we could get stuck forever if we happened to run out of PIO buffers from the verbs code, because the setup code wouldn't run; the interrupt was also ignored if SDMA was supported. We also have to reduce the pio update threshold if we have fewer kernel buffers than the existing threshold. Clean up the initialization a bit to get ordering safer and more sensible, and use the existing ipath_chg_kernavail call to do init, rather than doing it separately. Drop unnecessary clearing of pio buffer on pio parity error. Drop incorrect updating of pioavailshadow when exitting freeze mode (software state may not match chip state if buffer has been allocated and not yet written). If we couldn't get a kernel buffer for a while, make sure we are in sync with hardware, mainly to handle the exitting freeze case.

The loop in ipath_kreceive() that processes packets increments the loop-index 'i' once too often, because the exit condition does not depend on it, and is checked after the increment. By adding a check for !last to the iterator in the for loop, we correct that in a way that is not so likely to be re-broken by changes in the loop body.

Original patch from Mikulas Patocka <mpatocka@redhat.com> Mike Anderson was doing an OLTP benchmark on a computer with 48 physical disks mapped to one logical device via device mapper. He found that there was a slowdown on request_queue->lock in function generic_unplug_device. The slowdown is caused by the fact that when some code calls unplug on the device mapper, device mapper calls unplug on all physical disks. These unplug calls take the lock, find that the queue is already unplugged, release the lock and exit. With the below patch, performance of the benchmark was increased by 18% (the whole OLTP application, not just block layer microbenchmarks). So I'm submitting this patch for upstream. I think the patch is correct, because when more threads call simultaneously plug and unplug, it is unspecified, if the queue is or isn't plugged (so the patch can't make this worse). And the caller that plugged the queue should unplug it anyway. (if it doesn't, there's 3ms timeout).
