mkdir -p $plat_dir_new
git add $plat_dir_new

for dir in $omaps; do
	mach_dir_new="arch/arm/$dir/include/mach"
	for header in $mach_files; do
		file="$mach_dir_new/$header"

			git add $file
			if [ ! -f $plat_dir_new/$header ]; then

Earlier patch "omap: Remap L3, L4 to get more kernel io address space"
changed the VMALLOC_END.

However, this change causes problems on mach-omap1:

BUG: mapping for 0xe0000000 at 0xe0000000 overlaps vmalloc space
BUG: mapping for 0xe1000000 at 0xe1000000 overlaps vmalloc space

Fix this by creating separate vmalloc.h files for mach-omap1
and mach-omap2.

This patch remap L3 and L4 io space to get more kernel address space.
With this patch, 512 MB of IO space is reclaimed.
Some more combinations are possible but to make it uniform across
OMAP24XX, OMAP34XX and OMAP4430, these io combinations are chosen

Once this is reviewed and tested sufficiently, a documentation entry can
be created to ease up reading and debugging.

This patch splits OMAP2_IO_ADDRESS to OMAP2_L3_IO_ADDRESS and
OMAP2_L4_IO_ADDRESS to reclaim more IO space.

The omap_read*() and omap_write*() functions will work only over
L4 address space. Current omap kernel stack uses these functions
only to access registers over L4 io address space

Note that these macros should only be used when ioremap does
not work. Please use ioremap instead in all new code.

There is a possible race condition in clockdomain
code handling hw supported idle transitions.

When multiple autodeps dependencies are being added
or removed, a transition of still remaining dependent
powerdomain can result in false readings of the
state counter. This is especially fatal for off mode
state counter, as it could result in a driver not
noticing a context loss.

Fixed by disabling hw supported state transitions
when autodeps are being changed.
