The patch titled
Subject: syscalls.h: use gcc alias instead of assembler aliases for syscalls
has been removed from the -mm tree. Its filename was
syscallsh-use-gcc-alias-instead-of-assembler-aliases-for-syscalls.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Andi Kleen <ak@xxxxxxxxxxxxxxx>
Subject: syscalls.h: use gcc alias instead of assembler aliases for syscalls
Use standard gcc __attribute__((alias(foo))) to define the syscall aliases
instead of custom assembler macros.
This is far cleaner, and also fixes my LTO kernel build.
