> +Currently, <uapi/asm/sigcontext.h> provides common definitions for

> +
> +For this reason, a #include of <asm/sigcontext.h> was added in

> +included by the other headers as appropriate. This should allow
> +ptrace.h to be used alongside libc's sigcontext.h (if any) without
> +ill effects.
> +
> +This should make the situation unambiguous: <asm/sigcontext.h> is
> +the header to include for the sigframe-specific definitions, while
> +<asm/ptrace.h> is the header to include for ptrace-specific
> +definitions.
> +
> +To avoid conflicting with existing usage, <asm/sigcontext.h>
> +remains the canonical way to get the common definitions for
> +SVE_VQ_MIN, sve_vq_from_vl() etc., both in userspace and in the
> +kernel: relying on these being defined as a side effect of
> +including just <asm/ptrace.h> was never intended to be safe.

> +This is an amendment for
> +2322dc4 "linux-libc-headers: Fix build failure by using fixed temporary file instead of pipe"
> +which moves just the temporary input file from /tmp to build directory. But the
> +build directory may not in the same file system with the output file,
> +/dev/null, either and thus make it possible to trigger that bug, 67f846b, in
> +binutil v2.31.
> +
> +This patch puts both the input and output files into build directory for good.
