From bace7117d3fb59a6ed7ea1aa6c8994df6a28a72a Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 8 Jun 2015 21:20:26 +0200 Subject: [PATCH] x86/asm/entry: (Re-)rename __NR_entry_INT80_compat_max to __NR_syscall_compat_max Brian Gerst noticed that I did a weird rename in the following commit: b2502b418e63 ("x86/asm/entry: Untangle 'system_call' into two entry points: entry_SYSCALL_64 and entry_INT80_32") which renamed __NR_ia32_syscall_max to __NR_entry_INT80_compat_max. Now the original name was a misnomer, but the new one is a misnomer as well, as all the 32-bit compat syscall entry points (sysenter, syscall) share the system call table, not just the INT80 based one. Rename it to __NR_syscall_compat_max. Reported-by: Brian Gerst Cc: Andrew Morton Cc: Andy Lutomirski Cc: Borislav Petkov Cc: Denys Vlasenko Cc: H.
