linux-libc-headers: update to 5.x headers
Updating the linux-libc-headers to the 5.x kernel variant to match the latest reference kernel in the 2.7 release. We have two patches refreshed for context changes, and three patches dropped since they have been merged to the mainline kernel and are no longer necessary.

4Subject: [PATCH 2/3] arm64/sve: ptrace: Fix SVE_PT_REGS_OFFSET definition
5
6SVE_PT_REGS_OFFSET is supposed to indicate the offset for skipping
7over the ptrace NT_ARM_SVE header (struct user_sve_header) to the
8start of the SVE register data proper.
9
10However, currently SVE_PT_REGS_OFFSET is defined in terms of struct
11sve_context, which is wrong: that structure describes the SVE
12header in the signal frame, not in the ptrace regset.
13
14This patch fixes the definition to use the ptrace header structure
15struct user_sve_header instead.
16
17By good fortune, the to structures are the same size anyway, so
18there is no functional or ABI change.

4Subject: [PATCH 3/3] arm64/sve: Disentangle <uapi/asm/ptrace.h> from
5 <uapi/asm/sigcontext.h>
6
7Currently, <uapi/asm/sigcontext.h> provides common definitions for
8describing SVE context structures that are also used by the ptrace
9definitions in <uapi/asm/ptrace.h>.
10
11For this reason, a #include of <asm/sigcontext.h> was added in
12ptrace.h, but it this turns out that this can interact badly with
13userspace code that tries to include ptrace.h on top of the libc
14headers (which may provide their own shadow definitions for
15sigcontext.h).
16
17To make the headers easier for userspace to consume, this patch
18bounces the common definitions into an __SVE_* namespace and moves
19them to a backend header <uapi/asm/sve_context.h> that can be
20included by the other headers as appropriate. This should allow
21ptrace.h to be used alongside libc's sigcontext.h (if any) without
22ill effects.
23
24This should make the situation unambiguous: <asm/sigcontext.h> is
25the header to include for the sigframe-specific definitions, while
26<asm/ptrace.h> is the header to include for ptrace-specific
27definitions.
28
29To avoid conflicting with existing usage, <asm/sigcontext.h>
30remains the canonical way to get the common definitions for
31SVE_VQ_MIN, sve_vq_from_vl() etc., both in userspace and in the
32kernel: relying on these being defined as a side effect of
33including just <asm/ptrace.h> was never intended to be safe.
