Hi Santosh,

Which tree did you use to test this? It didn't seem to work for me

sometimes the system wouldn't suspend, complaining about USB suspend
errors; and other times I couldn't bring it out of suspend (by

a USB input device).
I might be doing something wrong...

the wfi() macro:

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.
