Patch from Tony Lindgren
This patch syncs the mainline kernel with linux-omap tree.
The highlights of the patch are:
- Convert more drivers to register resources in board-*.c to take
advantage of the driver model by David Brownell and Ladislav Michl
- Use set_irq_type() for GPIO interrupts instead of
omap_set_gpio_edge_ctrl() by David Brownell
- Add minimal support for handling optional add-on boards, such as
OSK Mistral board with LCD and keypad, by David Brownell
- Minimal support for loading functions to SRAM by Tony Lindgren
- Wake up from serial port by muxing RX lines temporarily into GPIO
interrupts by Tony Lindgren
- 32KHz sched_clock by Tony Lindgren and Juha YrjolaSigned-off-by: Tony Lindgren

A piece of the UML stubs patch got lost - it has
Killed STUBS_CFLAGS - it's not needed and the only remaining use had been
gratitious - it only polluted CFLAGS
in description and does remove it in arch/um/Makefile-x86_64, but forgets to
do the same in i386 counterpart. Lost chunk follows:Signed-off-by: Al Viro

Sanitized and fixed floppy dependencies: split the messy dependencies for
BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making
BLK_DEV_FD depend on that one and taking declarations of ARCH_MAY_HAVE_PC_FDC
to arch/*/Kconfig. While we are at it, fixed several obvious cases when
BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h
are *not* going to have floppy.c compile, let alone work).If you can come up with better name for that ("this architecture might
have working PC-compatible floppy disk controller"), you are more than
welcome - just s/ARCH_MAY_HAVE_PC_FDC/your_prefered_name/g in the patch
below...Signed-off-by: Al Viro

This patch fixes a race condition where in system used to hang or sometime
crash within minutes when kprobes are inserted on ISR routine and a task
routine.The fix has been stress tested on i386, ia64, pp64 and on x86_64. To
reproduce the problem insert kprobes on schedule() and do_IRQ() functions
and you should see hang or system crash.Signed-off-by: Anil S Keshavamurthy

This patch fixes a bug in kprobes's handling of a corner case on i386 and
x86_64. On an SMP system, if one CPU unregisters a kprobe just after
another CPU hits that probepoint, kprobe_handler() on the latter CPU sees
that the kprobe has been unregistered, and attempts to let the CPU continue
as if the probepoint hadn't been hit. The bug is that on i386 and x86_64,
we were neglecting to set the IP back to the beginning of the probed
instruction. This could cause an oops or crash.This bug doesn't exist on ppc64 and ia64, where a breakpoint instruction
leaves the IP pointing to the beginning of the instruction. I don't know
about sparc64. (Dave, could you please advise?)This fix has been tested on i386 and x86_64 SMP systems. To reproduce the
problem, set one CPU to work registering and unregistering a kprobe
repeatedly, and another CPU pounding the probepoint in a tight loop.Acked-by: Prasanna S Panchamukhi

This patch addresses a potential race condition for a case where Kprobe has
been removed right after another CPU has taken a break hit.The way this is addressed here is when the CPU that has taken a break hit
does not find its corresponding kprobe, then we check to see if the
original instruction got replaced with other than break. If it got
replaced with other than break instruction, then we continue to execute
from the replaced instruction, else if we find that it is still a break,
then we let the kernel handle this, as this might be the break instruction
inserted by other than kprobe(may be kernel debugger).Signed-off-by: Anil S Keshavamurthy

Background:
1) dmi_check_system() returns the count of the number of
matches. Zero thus means no matches.
2) A match callback can return nonzero to stop the match
checking.Bug: The count is incremented after we check for the nonzero return value,
so it does not reflect the actual count. We could say this is intended,
for some dumb reason, except that it means that a match on the first check
returns zero--no matches--if the callback returns nonzero.Attached patch implements the count before calling the callback and thus
before potentially short-circuiting.Signed-off-by: Robert Love

I've already sent this to the maintainers, and this is now being sent to a
larger community audience. I have fixed a problem with the ia64 version of
build_sched_domains(), but a similar fix still needs to be made to the
generic build_sched_domains() in kernel/sched.c.The "dynamic sched domains" functionality has recently been merged into
2.6.13-rcN that sees the dynamic declaration of a cpu-exclusive (a.k.a.
"isolated") cpuset and rebuilds the CPU Scheduler sched domains and sched
groups to separate away the CPUs in this cpu-exclusive cpuset from the
remainder of the non-isolated CPUs. This allows the non-isolated CPUs to
completely ignore the isolated CPUs when doing load-balancing.Unfortunately, build_sched_domains() expects that a sched domain will
include all the CPUs of each node in the domain, i.e., that no node will
belong in both an isolated cpuset and a non-isolated cpuset. Declaring a
cpuset that violates this presumption will produce flawed data structures
and will oops the kernel.To trigger the problem (on a NUMA system with >1 CPUs per node):
cd /dev/cpuset
mkdir newcpuset
cd newcpuset
echo 0 >cpus
echo 0 >mems
echo 1 >cpu_exclusiveI have fixed this shortcoming for ia64 NUMA (with multiple CPUs per node).
A similar shortcoming exists in the generic build_sched_domains() (in
kernel/sched.c) for NUMA, and that needs to be fixed also. The fix
involves dynamically allocating sched_group_nodes[] and
sched_group_allnodes[] for each invocation of build_sched_domains(), rather
than using global arrays for these structures. Care must be taken to
remember kmalloc() addresses so that arch_destroy_sched_domains() can
properly kfree() the new dynamic structures.Signed-off-by: John Hawkes

The i386 OProfile code has a function named nmi_exit(), which collides with
the nmi_exit() macro in linux/hardirq.h. At the moment, we get away with
it, because hardirq.h isn't included in the oprofile code. I hit this as a
bug when working with a patch which (indirectly) adds a #include of
hardirq.h to oprofile.Regardless, the name collision is probably not a good idea, so this patch
fixes it, renaming the oprofile function to op_nmi_exit(). It also renames
the nmi_init() and nmi_timer_init() functions similarly, for consistency.Signed-off-by: David Gibson
