Ok, so I decided to try this, because my new toy (Nehalem) showed some
absolutely horrid performance with the Fedora kernel that went away when I
compiled my own sane kernel.
And I suspect it's due to the audit path and auditd being enabled (for no
good reason that I can tell, except to slow everything down, since nobody
sane cares) by default.
HOWEVER. When I pull from your tree, I can no longer compile with the only
sane default (namely "CONFIG_AUDIT is stupid, nobody should use it"),
because I get
arch/x86/kernel/built-in.o: In function `auditsys':
signal_64.c:(.text+0x1f40): undefined reference to `audit_syscall_entry'
arch/x86/kernel/built-in.o: In function `sysret_audit':
signal_64.c:(.text+0x1f85): undefined reference to `audit_syscall_exit'

arch/x86/ia32/built-in.o: In function `sysretl_audit':
(.text+0x350): undefined reference to `audit_syscall_exit'
make: *** [.tmp_vmlinux1] Error 1
so while I would like to merge this, I really can't.
I'll test the performance anyway (with CONFIG_AUDIT enabled, of course).
