nmi_create_files() in arch/i386/oprofile/nmi_int.c depends on
model->num_counters (number of performance counters) being less than 10.
While this is currently the case, it's too clever by half.Other archs aren't quite as clever: they assume 100. I suggest to
normalize them all to 1000.Cc: Philippe Elie

There's a problem in drivers/bluetooth/dtl1_cs.c::dtl1_hci_send_frame()
If bt_skb_alloc() returns NULL, then skb_reserve(s, NSHL); will cause a
NULL pointer deref - ouch. If we can't allocate the resources we require
we need to tell the caller by returning -ENOMEM.Found by the coverity checker as bug #409

Convert kernel/cpu.c from semaphore to mutex.

It seems ppc64 wants to lock mutexes in early bootup code, with interrupts
disabled, and they expect interrupts to stay disabled, else they crash.Work around this bug by making mutex debugging variants save/restore irq
flags.Signed-off-by: Ingo Molnar

binfmt_flat.c calls set_personality with PER_LINUX as the personality.
On the arm architecture this results in the program running in 26bit
usermode. PER_LINUX_32BIT should be used instead. This doesn't affect
other architectures that use binfmt_flat.Signed-off-by: Greg Ungerer

Here is a patch to the system call handling for 5307/5272/etc to:
- fix the strace support (one tested the wrong bit)
- make all system calls a little bit faster by inlining set_esp0 and
supporting ENOSYS out of the critical path.
- remove extraneous spacesSigned-off-by: Greg Ungerer

This patch solve a bug triggered by execvp (this function use calloc to
store the argument list and gcc 3.4.x align the stack to word, not to dword).
This situation aren't related to signal handling and all 2.6.x have the bug.
On ColdFire targets we must force the stack to be aligned.Original patch from Andrea Tarani ,
