| Suresh Siddha | [patch 1/2] x86, fpu: split FPU state from task struct - v4
Split the FPU save area from the task struct. This allows easy migration
of FPU context, and it's generally cleaner. It also allows the following
two optimizations:
1) only allocate when the application actually uses FPU, so in the first
lazy FPU trap. This could save memory for non-fpu using apps. Next patch
does this lazy allocation.
2) allocate the right size for the actual cpu rather than 512 bytes always.
Patches enabling xsave/xrstor support (coming shortly) will take advantage
of this.

From: Robin Getz <rgetz@blackfin.uclinux.org>
Today, when module names are looked up, we do not qualify them (check to see
if the init section is still active or not). This can lead to problems when
kernel modules get loaded into the same address that the kernel init section
(or other module's init section was at). We sometimes return the old / no
lomnger there
This leads to bogus OOPS messages, and developers wasting their time looking

| Jeremy Fitzhardinge | preempt bug in set_pmd_pfn?
I think set_pmd_pfn, which is only called by __set_fixmap, might have a
preempt bug in it.
It can be executed with preemption enabled, but what if it gets preempted
set_pmd(pmd, pfn_pmd(pfn, flags));
/*
* It's enough to flush this one mapping.
* (PGE mappings get flushed as well)
__flush_tlb_one(vaddr);
}
?
Won't this leave a stale tlb on the old processor?
I noticed this because the Xen tlb flushing code effectively has a
smp_processor_id(), which provokes a warning when pr...

| Ingo Molnar | Re: preempt bug in set_pmd_pfn?
yes, and we had similar preemption bugs in the past. I guess most places
are either infrequent or have some natural atomicity anyway. Wanna send
a patch?

| Jeremy Fitzhardinge | Re: preempt bug in set_pmd_pfn?
Sure. Should it just disable preemption, or take a lock? It calls
set_pte_at without holding any pte locks; that seems to be relatively
common. Is it OK when you're operating on init_mm?

All of early setup runs with interrupts disabled, so there is no
need to set up early exception handlers for vectors >= 32
That saves some text size

The early exception handlers are currently set up using a macro
recursion. Replace that with a standard loop.
Noop patch, just a cleanup.

Currently they are in .text.head because the rest of head_64.S.
.text.head is not removed as init data, but the early exception handlers
should be because they are not needed after early boot of the BP.
So move them over.
