asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

by commit 9d1ee8ce92e1 ("um: Rewrite show_stack()").

um: Use generic runtime constant implementation2024-07-17T00:25:59ZLinus Torvaldstorvalds@linux-foundation.org2024-07-17T00:25:59Zurn:sha1:17e6a1213058d8759bcf043151c04612df55ebc4
UML should not be using the architecture native runtime constants, since
that requires also having the appropriate instruction fixups (and all
the linker script details).
Not that using that code would be impossible, but it's not worth it.
Just point UML at the generic version.

um: don't generate asm/bpf_perf_event.h2024-07-10T12:23:30ZArnd Bergmannarnd@arndb.de2024-05-13T17:13:55Zurn:sha1:0dd0e9437f8e500a384f12ec16bb407a49676147
If we start validating the existence of the asm-generic side of
generated headers, this one causes a warning:
make[3]: *** No rule to make target 'arch/um/include/generated/asm/bpf_perf_event.h', needed by 'all'. Stop.
The problem is that the asm-generic header only exists for the uapi
variant, but arch/um has no uapi headers and instead uses the x86
userspace API.
Add a custom file with an explicit redirect to avoid this.
