commit 700d3a5a66 upstream.
Revert
45e29d119e ("x86/syscalls: Make __X32_SYSCALL_BIT be unsigned long")
and add a comment to discourage someone else from making the same
mistake again.
It turns out that some user code fails to compile if __X32_SYSCALL_BIT
is unsigned long. See, for example [1] below.
[ bp: Massage and do the same thing in the respective tools/ header. ]
