65829ef5a0 These changes deal with the issues of relative includes
introduced by the earlier clean-up and clean up few more
 things for enabling multiplatform support.
 
 The multiplatform kernel has been booted on omaps on
 top of this branch with the work-in-progress patches
 applied manually.
 
 We cannot yet enable the multiplatform support though.
 We still need the common clock framework patches, some
 solution for dma-omap.h, and serial-omap.h moved before
 we can enable it.

6ba54ab4a4 ARM: OMAP: Remove omap_init_consistent_dma_size()
The only thing omap_init_consistent_dma_size() does is increase the
consistent DMA size if CONFIG_FB_OMAP_CONSISTENT_DMA_SIZE is defined.
Increasing the consistent DMA size should no longer be needed with CMA
in place.

This patch removes omap_init_consistent_dma_size() and also
arch/arm/mach-omap2/io.c:omap_common_init_early() which becomes an empty
function.

This is based on the following minimal topic branches
 coordinated with the related driver maintainers:
 
 omap-for-v3.8/cleanup-headers-usb
 omap-for-v3.8/cleanup-headers-menelaus
 
 In addition to that, there are few fixes to the previously

1c7ebf17a4 These changes remove plat/serial.h usage for omap2+.
Note that this branch is based on a tty commit 3e9a6321
 (tty/serial/8250: Make omap hardware workarounds local to 8250.h)
 merged with omap-for-v3.8/cleanup-headers-signed.
 
 The tty commit is needed to keep things compiling for omaps,
 and omap-for-v3.8/cleanup-headers-signed is needed to avoid
 multiple merge conflicts with the includes. I've verified
 with Greg KH that the tty commit above is immutable and OK
 to use as a base.

873e698067 ARM: OMAP: Remove NEED_MACH_GPIO_H
Omap no longer needs this option, mach/gpio.h is
empty.

Also remove mach/irqs.h from gpio-omap.h and
include it directly from the related omap1
gpio init files.

Otherwise omap2+ build fails for MULTI_PLATFORM.

are.

Note that we can now also remove the relative includes

1bf11c5353 percpu-rw-semaphores: use rcu_read_lock_sched
Use rcu_read_lock_sched / rcu_read_unlock_sched / synchronize_sched
instead of rcu_read_lock / rcu_read_unlock / synchronize_rcu.

This is an optimization. The RCU-protected region is very small, so
there will be no latency problems if we disable preempt in this region.

So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates
to preempt_disable / preempt_disable. It is smaller (and supposedly
faster) than preemptible rcu_read_lock / rcu_read_unlock.
