ARC: switch to generic ENTRY/END assembler annotations 2014-03-26T09:01:28+00:00 Vineet Gupta vgupta@synopsys.com 2014-02-07T08:17:43+00:00 ec7ac6afd07b2d958aab9dfc0a686300b856922a With commit 9df62f054406 "arch: use ASM_NL instead of ';'" the generic macros can handle the arch specific newline quirk. Hence we can get rid of ARC asm macros and use the "C" style macros. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

ARC: [SMP] Fix build failures for large NR_CPUS 2013-11-06T05:11:46+00:00 Vineet Gupta vgupta@synopsys.com 2013-11-01T05:16:40+00:00 57e26e57454fae4f1d15c2e9fa965b7a8046ab34 ST.as only takes S9 (255) for offset. This was going out of range when accessing a task_struct field with 4k NR_CPUS (due to 128b of coumaks itself in there). Workaround by using an intermediate register to do the address scaling. There is some duplication of fix for ctx_sw.c and ctx_sw_asm.S however given that C version will go away soon I'm not bothering to factor out the common code.

There is some duplication of fix for ctx_sw.c and ctx_sw_asm.S however
given that C version will go away soon I'm not bothering to factor out
