x86: Fix movq immediate operand constraints in uaccess_64.h

Browse source

arch/x86/include/asm/uaccess_64.h uses wrong asm operand constraint
("ir") for movq insn. Since movq sign-extends its immediate operand,
"er" constraint should be used instead.

Attached patch changes all uses of __put_user_asm in uaccess_64.h to use
"er" when "q" insn suffix is involved.

Patch was compile tested on x86_64 with defconfig.
