x86/asm/entry: Move the arch/x86/syscalls/ definitions to arch/x86/entry/syscalls/ The build time generated syscall definitions are entry code related, move them into the arch/x86/entry/ directory.

UAPI: x86: Differentiate the generated UAPI and internal headers Differentiate the generated UAPI and internal headers during generation such that the UAPI headers can be installed elsewhere. A later patch will use this to move the UAPI headers to: arch/x86/include/generated/uapi/asm/ to make them easier to handle. A previous patch added a -I for this path.
