X-Git-Tag: v3.5-rc1~105^2~5 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a54f1655be4cb103a6729adcc9ca914c5fdf1ca0;p=pandora-kernel.git m68k: add TIF_NOTIFY_RESUME and handle it. TIF_NOTIFY_RESUME added (as bit 5). That way nommu glue needs no changes at all; mmu one needs just to replace jmi do_signal_return to jne do_signal_return There we have flags shifted up, until bit 6 (SIGPENDING) is in MSBit; instead of checking that MSBit is set (jmi) we check that MSBit or something below it is set (jne); bits 0..4 are never set, so that's precisely "bit 6 or bit 5 is set". Usual handling of NOTIFY_RESUME/SIGPENDING is done in do_notify_resume(); glue calls it instead of do_signal(). Signed-off-by: Al Viro --- Reading git-diff-tree failed
