| |
Fix ssbd.c which depends implicitly on asm/ptrace.h including linux/prctl.h (through for example linux/compat.h, then linux/time.h, linux/seqlock.h, linux/spinlock.h and linux/irqflags.h), and uses PR_SPEC* defines.
This is an issue since we'll remove the include in the next commit.
Fixes: 9cdc0108baa8 ("arm64: ssbd: Add prctl interface for per-thread mitigation") Cc: stable@vger.kernel.org Signed-off-by: Anisse Astier <aastier@freebox.fr> --- Contrary to what I said in the previous email, I can reproduce the build error on Linus' master when ARM64_SSBD is enabled.
Changes since v2: - fix build when ARM64_SSBD is enabled with additionnal patch Changes since v1: - made a bit more explicit that we copied defined symbols, in commit and code. - Use Fixes: tag in commit message
