[PATCH] sched: Replace __ASSEMBLY__ with __ASSEMBLER__ in sched.h header

[PATCH] sched: Replace __ASSEMBLY__ with __ASSEMBLER__ in sched.h header

[Thomas Huth]

While the GCC and Clang compilers already define __ASSEMBLER__ auto-
matically when compiling assembly code, __ASSEMBLY__ is a macro that
only gets defined by the Makefiles in the kernel. This can be very
confusing when switching between userspace and kernelspace coding, or
when dealing with uapi headers that rather should use __ASSEMBLER__
instead. Let's standardize now on the __ASSEMBLER__ macro to avoid
this confusion.

 Note: This has been split from an earlier bigger patch of mine into
       this separate patch to ease reviewing.
       I also thought I had sent out this earlier already, but I cannot
       find the patch on lore or any other public inbox anymore, so maybe
       it got lost along the way. Anyway, sorry if you got this twice!
