the wfi() macro:

Dave Martin (5):
ARM: omap4: Provide do_wfi() for Thumb-2
ARM: omap4: Convert END() to ENDPROC() for correct linkage with
CONFIG_THUMB2_KERNEL
ARM: omap3: Remove hand-encoded SMC instructions
ARM: omap3
For CONFIG_THUMB2_KERNEL, the existing definition of do_wfi() will
insert invalid code into the instruction stream.
Any assembler which can assemble Thumb-2 is guaranteed to accept
the wfi mnemonic, so for the Thumb-2 case, just use the mnemonic.
The ARM case is left as-is.

For v6, wfi is architected as a defined MCR instruction, so
use that definition.
Doing a no-op instead of wfi() is probably bad, so for older
processors than v6, wfi() is not defined. If needed, some CPU-
specific wfi() will have to be defined elsewhere.

sometimes the system wouldn't suspend, complaining about USB suspend

Now that wfi() in asm/system.h is suitably generic, we can
remove the omap-specific do_wfi() macro.
