None of these files use any of the functionality promised by
asm/semaphore.h. It's possible that they rely on it dragging in some
unrelated header file, but I can't build all these files, so we'll have
fix any build failures as they come up.Signed-off-by: Matthew Wilcox

This patch changes 24xx to use shared clock code and new register
access.Note that patch adds some temporary OLD_CK defines to keep patch
more readable. These temporary defines will be removed in the next
patch. Also not all clocks are changed in this patch to limit the
size.Also, the patch fixes few incorrect clock defines in clock24xx.h.

This patch changes 24xx to use new register access, except for clock
framework. Clock framework register access will get updates in the
next patch.Note that board-*.c files change GPMC (General Purpose Memory Controller)
access to use gpmc_cs_write_reg() instead of accessing the registers
directly. The code also uses gpmc_fck instead of it's parent clock
core_l3_ck for GPMC clock.The H4 board file also adds h4_init_flash() function, which specify the
flash start and end addresses.Also note that sleep.S removes some unused registers addresses.

Move now OMAP1-specific timer32k code to mach-omap1 since OMAP2/3 32k
timers are done in gptimer code.Signed-off-by: Kevin Hilman
Signed-off-by: Tony Lindgren -
Since 32k timer code is moving to OMAP1 specific dir, move the
32k-based sched_clock() into common code where it is based on the 32k
sync counter and can be used even when using MPU timer.While moving, change the ticks-to-nsecs conversion to use the helper
functions provided by clocksource.h.Also removed the unused ticks_to_usec, leaving only ticks_to_nsec.

On OMAP2/3, the gp-timer code can be used for a 32kHz timer simply by
setting the source to be the 32k clock instead of sys_clk.This patch uses the mach-omap2/timer-gp.c code for 32kHz timer on
OMAP2, moving the logic into mach-omap2/timer-gp.c, and not using
plat-omap/timer32k.c which, for OMAP2, is redundant with the timer-gp
code.Also, if CONFIG_OMAP_32K_TIMER is enabled, the gptimer-based
clocksource is not used. Instead the default 32k sync counter is used
as the clocksource (see the clocksource in plat-omap/common.c.) This
is important for sleep/suspend so there is a valid counter during
sleep. Note that the suspend/sleep code needs fixing to check for
overflows of this counter.In addition, the OMAP2/3 details are removed from timer32k.c leaving
that with only OMAP1 specifics. A follow-up patch will move it from
plat-omap common code to mach-omap1.Signed-off-by: Kevin Hilman

Currently, the GPIO interrupt handling is duplicating some of the work
done by the generic IRQ handlers (handle_edge_irq, handle_level_irq)
such as detecting nesting, handling re-triggers etc. Remove this
duplication and use generic hooks based on IRQ type.Using generic IRQ handlers ensures correct behavior when using
threaded interrupts introduced by the -rt patch.Signed-off-by: Kevin Hilman
Signed-off-by: Tony Lindgren -
The clearing was moved to the unmask hook because it is known to run
after the interrupt handler has actually run. Before this patch, if
interrupts are threaded, the clearing/unmasking of level triggered
interrupts would be done before the threaded handler actually ran.Signed-off-by: Kevin Hilman

This patchset adds a flags variable to reserve_bootmem() and uses the
BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions
between crashkernel area and already used memory.This patch:
Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE.
If that flag is set, the function returns with -EBUSY if the memory already
has been reserved in the past. This is to avoid conflicts.Because that code runs before SMP initialisation, there's no race condition
inside reserve_bootmem_core().[akpm@linux-foundation.org: coding-style fixes]

smc91x is shared between many different platforms. Each platform needs
to specify the interrupt type, and in some cases the irq type depends
on more than just the build configuration - it depends on runtime
checks.Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide
a way for these flags to be passed via the IRQ resource itself.Note that IRQF_TRIGGER_* constants are intentionally defined to correspond
with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that
the low bits of PCI iomem resources correspond with the BAR flag bits.Also provide a way to configure smc91x to read the IRQ flags from the
resource. Once all platforms have been converted over (signified
by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should
be removed.Signed-off-by: Russell King

This patch converts arm's OMAP mailbox driver to use
blk_end_request interfaces.If the original code was converted literally, blk_end_request would
be called with '-EIO' because end_that_request_last() were called
with '0' (i.e. failure).
But I think these '0's are bugs in the original code because it's
unlikely that all requests are treated as failure.
(The bugs should have no effect unless these requests have an end_io
callback.)So I changed them to pass '0' (i.e. success) to blk_end_request.
