x86/asm/entry: (Re-)rename __NR_entry_INT80_compat_max to __NR_syscall_compat_max

2015-06-08T21:43:38+00:00

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.

x86/asm/entry: Rename compat syscall entry points

2015-06-08T06:47:36+00:00

Rename the following system call entry points: ia32_cstar_target -> entry_SYSCALL_compat ia32_syscall -> entry_INT80_compat The generic naming scheme for x86 system call entry points is: entry_MNEMONIC_qualifier where 'qualifier' is one of _32, _64 or _compat.

x86/asm/entry: Move the vsyscall code to arch/x86/entry/vsyscall/

2015-06-04T05:37:37+00:00

The vsyscall code is entry code too, so move it to arch/x86/entry/vsyscall/. Cc: Borislav Petkov Cc: H. Peter Anvin Cc: Linus Torvalds Cc: Thomas Gleixner Cc: Andy Lutomirski Cc: Denys Vlasenko Cc: Brian Gerst Cc: Peter Zijlstra Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar
