x86: uaccess: return value of __{get|put}_user() can be int
Impact: cleanup The type of return value of __{get|put}_user() can be int. There is no user to refer the return value of __{get|put}_user() as long. This reduces code size a bit on 64-bit. $ size vmlinux.* text data bss dec hex filename 4509265 479988 673588 5662841 566879 vmlinux.new 4511462 479988 673588 5665038 56710e vmlinux.old Signed-off-by: Hiroshi Shimamoto <h-shimamoto@ct.jp.nec.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
