2009-04-10x86, intr-remap: fix eoi for interrupt remapping without x2apicWeidong Han1-1/+4
To simplify level irq migration in the presence of interrupt-remapping, Suresh used a virtual vector (io-apic pin number) to eliminate io-apic RTE modification. Level triggered interrupt will appear as an edge to the local apic cpu but still as level to the IO-APIC. So in addition to do the local apic EOI, it still needs to do IO-APIC directed EOI to clear the remote IRR bit in the IO-APIC RTE. Pls refer to Suresh's patch for more details (commit 0280f7c416c652a2fd95d166f52b199ae61122c0). Now interrupt remapping is decoupled from x2apic, it also needs to do the directed EOI for apic. Otherwise, apic interrupts won't work correctly.

It is because the return value of tracing_buffers_splice_read() does not include "zero out any left over data" bytes. But tracing_buffers_read() includes these bytes, we make them consistent.

2009-04-10[ALSA] pcm-midlevel: Add more strict buffer position checks based on jiffiesJaroslav Kysela2-9/+41
Some drivers like Intel8x0 or Intel HDA are broken for some hardware variants. This patch adds more strict buffer position checks based on jiffies when internal hw_ptr is updated.

I found two issues with ICH7-M (it should be related to other HDA chipsets as well): - the ring buffer position is not reset when stream restarts (after xrun) - solved by moving azx_stream_reset() call from open() to prepare() callback and reset posbuf to zero (it might be filled with hw later than position() callback is called) - irq_ignore flag should be set also when ring buffer memory area is not changed in prepare() callback - this patch replaces irq_ignore with more universal check based on jiffies clock Signed-off-by: Jaroslav Kysela <perex@perex.cz>

2009-04-09keys: Handle there being no fallback destination keyring for request_key()David Howells1-3/+6
When request_key() is called, without there being any standard process keyrings on which to fall back if a destination keyring is not specified, an oops is liable to occur when construct_alloc_key() calls down_write() on dest_keyring's semaphore. Due to function inlining this may be seen as an oops in down_write() as called from request_key_and_link(). This situation crops up during boot, where request_key() is called from within the kernel (such as in CIFS mounts) where nobody is actually logged in, and so PAM has not had a chance to create a session keyring and user keyrings to act as the fallback. To fix this, make construct_alloc_key() not attempt to cache a key if there is no fallback key if no destination keyring is given specifically.

2009-04-09mutex: have non-spinning mutexes on s390 by defaultHeiko Carstens3-1/+6
Impact: performance regression fix for s390 The adaptive spinning mutexes will not always do what one would expect on virtualized architectures like s390. Especially the cpu_relax() loop in mutex_spin_on_owner might hurt if the mutex holding cpu has been scheduled away by the hypervisor. We would end up in a cpu_relax() loop when there is no chance that the state of the mutex changes until the target cpu has been scheduled again by the hypervisor. For that reason we should change the default behaviour to no-spin on s390. We do have an instruction which allows to yield the current cpu in favour of a different target cpu. Also we have an instruction which allows us to figure out if the target cpu is physically backed. However we need to do some performance tests until we can come up with a solution that will do the right thing on s390.

2009-04-09sched: do not count frozen tasks toward loadNathan Lynch1-1/+2
Freezing tasks via the cgroup freezer causes the load average to climb because the freezer's current implementation puts frozen tasks in uninterruptible sleep (D state). Some applications which perform job-scheduling functions consult the load average when making decisions. If a cgroup is frozen, the load average does not provide a useful measure of the system's utilization to such applications. This is especially inconvenient if the job scheduler employs the cgroup freezer as a mechanism for preempting low priority jobs. Contrast this with using SIGSTOP for the same purpose: the stopped tasks do not count toward system load. Change task_contributes_to_load() to return false if the task is frozen. This results in /proc/loadavg behavior that better meets users' expectations.

2009-04-09tracing/syscalls: use a dedicated file headerFrederic Weisbecker6-32/+41
Impact: fix build warnings and possibe compat misbehavior on IA64 Building a kernel on ia64 might trigger these ugly build warnings: CC arch/ia64/ia32/sys_ia32.o In file included from arch/ia64/ia32/sys_ia32.c:55: arch/ia64/ia32/ia32priv.h:290:1: warning: "elf_check_arch" redefined In file included from include/linux/elf.h:7, from include/linux/module.h:14, from include/linux/ftrace.h:8, from include/linux/syscalls.h:68, from arch/ia64/ia32/sys_ia32.c:18: arch/ia64/include/asm/elf.h:19:1: warning: this is the location of the previous definition [...] sys_ia32.c includes linux/syscalls.h which in turn includes linux/ftrace.h to import the syscalls tracing prototypes. But including ftrace.h can pull too much things for a low level file, especially on ia64 where the ia32 private headers conflict with higher level headers. Now we isolate the syscall tracing headers in their own lightweight file.
