VMALLOC_END is supposed to be an absolute value, while PAGE_OFFSET may
vary depending on the selected user:kernel memory split mode through
CONFIG_VMSPLIT_*. In fact, the goal of moving PAGE_OFFSET down is to
accommodate more directly addressed RAM by the kernel below the vmalloc
area, and having VMALLOC_END move along PAGE_OFFSET is rather against
the very reason why PAGE_OFFSET can be moved in the first place.

Commit 5a5f561 (convert OMAP3 PRCM macros to the _SHIFT/_MASK suffixes)
mistakenly removed the check for PER when disabling the IO chain.
During idle, if the PER powerdomain transitions into a lower state
and CORE does not, the IO pad wakeups are not being disabled in
the idle path after they are enabled. This can happen with the
lower C-states when using CPUidle for example.
This patch ensures that the check for disabling IO wakeups also checks
for PER transitions, matching the check done to enable IO wakeups.
Found when debugging PM/CPUidle related problems reported by Ameya
Palande <ameya.palande@nokia.com>. Problems were triggered
particularily on boards with UART2 consoles (n900, Overo) since UART2
is in the PER powerdomain.
Tested on l-o master (omap3_defonfig + CONFIG_CPU_IDLE=y) as well
as with current PM branch. Boards tested: n900, Overo, omap3evm.

cpu_is_omap3517() and cpu_is_omap3505() are the subgroups of cpu_is_omap34xx(),
so we should check cpu_is_omap3517() and cpu_is_omap3505() first, then check
cpu_is_omap34xx().
Otherwise, All AM35XX (Sitara) clocks do not get registered and device drivers

enabled could result in incorrect register restores as
the OMAP exits off-mode. This could potentially result in

OMAP3530 CBB package can have GPIO126 muxed on 2 pins: mmc1_dat4 and
cam_strobe. This causes a problem with current multipath GPIO mux
handling, which muxes both pins as GPIO126 and makes the GPIO unusable.
Fix this by not muxing any pins if multipath GPIO is detected and
just print a warning instead. It's up to board files to set correct
mux using omap_mux_init_signal and pin name.
