Ammar Faizi a8816afcaf x86: um: vdso: Add '%rcx' and '%r11' to the syscall clobber list ... [ Upstream commit 5541992e512de8c9133110809f767bd1b54ee10d ] The 'syscall' instruction clobbers '%rcx' and '%r11', but they are not listed in the inline Assembly that performs the syscall instruction. No real bug is found. It wasn't buggy by luck because '%rcx' and '%r11' are caller-saved registers, and not used in the functions, and the functions are never inlined. Add them to the clobber list for code correctness.
