-Subject: [PATCH] arm64/sve: <uapi/asm/ptrace.h> should not depend on
- <uapi/linux/prctl.h>
-
-Pulling linux/prctl.h into asm/ptrace.h in the arm64 UAPI headers causes
-userspace build issues for any program (e.g. strace and qemu) that
-includes both <sys/prctl.h> and <linux/ptrace.h> when using musl libc:
-
- | error: redefinition of 'struct prctl_mm_map'
- | struct prctl_mm_map {
-
-See https://github.com/foundriesio/meta-lmp/commit/6d4a106e191b5d79c41b9ac78fd321316d3013c0
-for a public example of people working around this issue.
-
-Although it's a bit grotty, fix this breakage by duplicating the prctl
-constant definitions. Since these are part of the kernel ABI, they
-cannot be changed in future and so it's not the end of the world to have
-them open-coded.

-Fixes: 43d4da2c45b2 ("arm64/sve: ptrace and ELF coredump support")

-Upstream-Status: Backport [https://github.com/torvalds/linux/commit/35341ca0614ab13e1ef34ad4f29a39e15ef31fa8]
