From 0f78ff17112d8b3469b805ff4ea9780cc1e5c93b Mon Sep 17 00:00:00 2001 From: Brian Gerst Date: Fri, 13 Mar 2020 15:51:43 -0400 Subject: x86/entry: Drop asmlinkage from syscalls asmlinkage is no longer required since the syscall ABI is now fully under x86 architecture control. This makes the 32-bit native syscalls a bit more effecient by passing in regs via EAX instead of on the stack.
