Subject: [PATCH 2/7] tools headers uapi: Update tools's copy of asm-generic/unistd.h

From: Arnaldo Carvalho de Melo <acme@...hat.com>

To get the changes in:

	db7a2d1809a5 ("asm-generic: unistd.h: Wire up sys_rseq")

That wires up the new 'rsec' system call, which will automagically
support that syscall in the syscall table used by 'perf trace' on
arm/arm64.

This cures the following warning during perf's build:

	Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/unistd.h' differs from latest version at 'include/uapi/asm-generic/unistd.h'
	diff -u tools/include/uapi/asm-generic/unistd.h include/uapi/asm-generic/unistd.h
