Please make sure you have proper line wraps. Lines in checkin comments should be no longer than 70 characters normally. > Signed-off-by: Jonas Jensen <[email protected]> Acked-by: Arnd Bergmann <[email protected]> Since this patch is independent from the actual platform support, it should go through Russell's patch tracker at http://www.arm.linux.org.uk/developer/patches/ > arch/arm/mm/proc-fa526.S | 4 +--- > 1 files changed, 1 insertions(+), 3 deletions(-) > > diff --git a/arch/arm/mm/proc-fa526.S b/arch/arm/mm/proc-fa526.S > index d217e97..85280b1 100644 > --- a/arch/arm/mm/proc-fa526.S > +++ b/arch/arm/mm/proc-fa526.S > @@ -81,9 +81,7 @@ ENDPROC(cpu_fa526_reset) > */ > .align 4 > ENTRY(cpu_fa526_do_idle) > - mcr p15, 0, r0, c7, c0, 4 @ Wait for interrupt > - mov pc, lr > - > + nop > > ENTRY(cpu_fa526_dcache_clean_area) > 1: mcr p15, 0, r0, c7, c10, 1 @ clean D entry Adding Imre and Florian to Cc for Gemini. They might have a comment about this. I think we should delete arch/arm/mach-gemini/idle.c after this as well.
