cool! A few comments about the patches that affect arch/x86:

dmi_blacklist.patch:

+#ifdef CONFIG_DMI_SCAN
dmi_scan_machine();
+#endif

put that #ifdef into the include file and make it an inlined NOP in the
!DMI_SCAN case. That de-#ifdef-ifies the .c files.

cpu-support.patch: ditto.

mtrr.patch: ditto.

inflate-error.patch: please use:

quilt refresh --diffstat --sort --no-timestamps -p 1

when generating patches, to make them reviewable, uniform and
noise-free.

no-doublefault.patch: looks ok. Please add proper metadata and submit to
lkml.

sbf.patch: looks ok.

sysenter.patch:

+#ifdef CONFIG_SYSENTER
sysenter_setup();
enable_sep_cpu();
+#endif

hide these #ifdefs in the include file. (as it already does) Looks ok
otherwise.

threadinfo-ool.patch: doesnt this break the scheduler? Had something
like this in -rt, i turned 'current' into a const actually, but had
trouble with keeping from gcc to do the right thing in sched.c. I guess
we could live with current_non_const() that gets it from assembly. (and
hence gcc wont be able to optimize it away in the middle of the
context-switch) But when done properly, this is both a nice, measurable
speedup on UP, and a nice space-saver.

tiny-cflags.patch: obsolete? Isnt CFLAGS already extendable? Question to
Sam i guess.

tsc.patch: look ok. needs x86.git porting.

Ingo
