-Subject: [PATCH] um: Allow building and running on older hosts
-
-[ Upstream commit 0a987645672ebde7844a9c0732a5a25f3d4bb6c6 ]
-
-Commit a78ff1112263 ("um: add extended processor state save/restore
-support") and b6024b21fec8 ("um: extend fpstate to _xstate to support
-YMM registers") forced the use of the x86 FP _xstate and
-PTRACE_GETREGSET/SETREGSET. On older hosts, we would neither be able to
-build UML nor run it anymore with these two commits applied because we
-don't have definitions for struct _xstate nor these two ptrace requests.
-
-We can determine at build time which fp context structure to check
-against, just like we can keep using the old i387 fp save/restore if
-PTRACE_GETRESET/SETREGSET are not defined.

-Subject: [PATCH] um: Fix check for _xstate for older hosts
-
-Commit 0a987645672e ("um: Allow building and running on older
-hosts") attempted to check for PTRACE_{GET,SET}REGSET under the premise
-that these ptrace(2) parameters were directly linked with the presence
-of the _xstate structure.
-
-After Richard's commit 61e8d462457f ("um: Correctly check for
-PTRACE_GETRESET/SETREGSET") which properly included linux/ptrace.h
-instead of asm/ptrace.h, we could get into the original build failure
-that I reported:
-
-arch/x86/um/user-offsets.c: In function 'foo':
-arch/x86/um/user-offsets.c:54: error: invalid application of 'sizeof' to
-incomplete type 'struct _xstate'
-
-On this particular host, we do have PTRACE_GETREGSET and
-PTRACE_SETREGSET defined in linux/ptrace.h, but not the structure
-_xstate that should be pulled from the following include chain: signal.h
--> bits/sigcontext.h.
-
-Correctly fix this by checking for FP_XSTATE_MAGIC1 which is the correct
-way to see if struct _xstate is available or not on the host.
-
-Fixes: 61e8d462457f ("um: Correctly check for PTRACE_GETRESET/SETREGSET")
-Fixes: 0a987645672e ("um: Allow building and running on older hosts")
