2011-05-10MIPS: Hibernation: Fixes for PAGE_SIZE >= 64kbWu Zhangjin
PAGE_SIZE >= 64kb (1 << 16) is too big to be the immediate of the addiu/daddiu instruction, so, use addu/daddu instruction instead. The following compiling error is fixed: AS arch/mips/power/hibernate.o arch/mips/power/hibernate.S: Assembler messages: arch/mips/power/hibernate.S:38: Error: expression out of range make[2]: *** [arch/mips/power/hibernate.o] Error 1 make[1]: *** [arch/mips/power] Error 2 Reported-by: Roman Mamedov <rm@romanrm.ru> Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> To: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/2313/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2009-09-17MIPS: Use PAGE_SIZE in assembly instead of _PAGE_SIZE.Nelson Elhage
Now that PAGE_SIZE is available to assembly directly, there is no need to separately expose it as _PAGE_SIZE through asm-offsets. In addition, remove _PAGE_SHIFT from asm-offsets, since it was never needed, and is not used anywhere.

2009-06-24MIPS: Hibernation: Remove SMP TLB and cacheflushing code.Ralf Baechle
We can't perform any flushes on SMP from swsusp_arch_resume because interrupts are disabled. A cross-CPU flush is unnecessary anyway because all but the local CPU have already been disabled. A local flush is not needed either because we didn't change any mappings. So just delete the code. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-06-17MIPS: Add hibernation supportWu Zhangjin
[Ralf: SMP support requires CPU hotplugging which MIPS currently doesn't support. As implemented in this patch cache and tlb flushing will also be invoked with interrupts disabled so smp_call_function() will blow up in charming ways. So limit to !SMP.] Reviewed-by: Pavel Machek <pavel@ucw.cz> Reviewed-by: Yan Hua <yanh@lemote.com> Reviewed-by: Arnaud Patard <apatard@mandriva.com> Reviewed-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Hu Hongbing <huhb@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
