Re: [PATCH] arc: kernel: export symbol for pm_power_off in reset.c

[Chen Gang]

After this patch, and with limitations below, arc finishes allmodconfig.

 - with EXTRA_CFLAGS=-mmedium-calls.

 - disable CONFIG_CC_OPTIMIZE_FOR_SIZE.

 - by pass 5-7 gcc issues (4-5 may duplicate).

 - by pass 1 binutils issue (when disable CONFIG_CC_OPTIMIZE_FOR_SIZE).


Next (within 2013-10-31) I will/should:

 - shrink cross-compilers information, at least.

 - finish the patch for "portable assembler code - newline"


Left:

 - it also content sevaval warnings (even not use "EXTRA_CFLAGS=-W").

 - for next-20130927 tree, arc can not pass defconfig, either.

 - not let it run under kvm (I don't know whether we support kvm).


Thanks.
