Building omap2plus_defconfig (which enables support for
OMAP2420/2430/OMAP3
and OMAP4 in one image), I get the following build error.
CC arch/arm/kernel/swp_emulate.o
/tmp/ccg979qz.s: Assembler messages:
/tmp/ccg979qz.s:343: Error: selected processor does not support ARM mode
`ldrexb r6,[r5]'
/tmp/ccg979qz.s:344: Error: selected processor does not support ARM mode
`strexb r1,r3,[r5]'
make[1]: *** [arch/arm/kernel/swp_emulate.o] Error 1
make: *** [arch/arm/kernel] Error 2
I'm using CodeSourcery's 2010q1-202 toolchain based on gcc 4.4.1.
I haven't been following the lists closely the last few days, so I'm not
sure if this is a known issue. Just reporting it for now.

This seems to be related to "ARM: Add SWP/SWPB emulation for ARMv7 processors (v5)"
where SWP_EMULATE is selected by default. For the omap2plus_defconfig in for-next
we now have CPU_V6 and CPU_V7 set with SMP and SMP_ON_UP.

Tony

I had forgotten I'd reported this earlier. I reported the build break
again today, and Catalin provided this patch [1] which solves the
build issue.
