Mark Rutland 870d16757b arm64: make _TIF_WORK_MASK bits contiguous ... We need the bits of _TIF_WORK_MASK to be contiguous in order to to use this as an immediate argument to an AND instruction in entry.S. We happened to change these bits in commits: b5a5a01d8e ("arm64: uaccess: remove addr_limit_user_check()") 192caabd4d ("arm64: add support for TIF_NOTIFY_SIGNAL") which each worked in isolation, but the merge resolution in commit: 005b2a9dc8 ("Merge tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block") happened to make the bits non-contiguous. Fix this by moving TIF_NOTIFY_SIGNAL to be bit 6, which is contiguous with the rest of _TIF_WORK_MASK. Otherwise, we'll get a build-time failure as below: arch/arm64/kernel/entry.S: Assembler messages: arch/arm64/kernel/entry.S:733: Error: immediate out of range at operand 3 -- `and x2,x19,#((1<<1)|(1<<0)|(1<<2)|(1<<3)|(1<<4)|(1<<5)|(1<<7))' scripts/Makefile.build:360: recipe for target 'arch/arm64/kernel/entry.o' failed Fixes: 005b2a9dc8 ("Merge tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block") Signed-off-by: Mark Rutland <mark.rutland@arm.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Will Deacon <will@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2020-12-16 14:08:47 -08:00
