Vineet Gupta db911277a2 ARC: unbork 5.11 bootup: fix snafu in _TIF_NOTIFY_SIGNAL handling ... [ Upstream commit bb12433bf5 ] Linux 5.11.rcX was failing to boot on ARC HSDK board. Turns out we have a couple of issues, this being the first one, and I'm to blame as I didn't pay attention during review. TIF_NOTIFY_SIGNAL support requires checking multiple TIF_* bits in kernel return code path. Old code only needed to check a single bit so BBIT0 <TIF_SIGPENDING> worked. New code needs to check multiple bits so AND <bit-mask> instruction. So needs to use bit mask variant _TIF_SIGPENDING Cc: Jens Axboe <axboe@kernel.dk> Fixes: 53855e1258 ("arc: add support for TIF_NOTIFY_SIGNAL") Link: https://github.com/foss-for-synopsys-dwc-arc-processors/linux/issues/34 Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2023-01-04 11:39:21 +01:00
