The interrupt stack table (IST) mechanism is the only thing preventing
kvm from deferring saving and reloading of some significant state. It
is also somewhat complicated.
Remove it by switching the special exceptions to use the normal irqstack.
Changes from v1:
- rebase on tip/master
- as a step, consolidate stack switching into a single macro
Jeremy, Xen is also affected; please review.
Avi Kivity (4):
x86: drop the use of the tss interrupt stack table (IST)
x86: Consolidate irq stack switching to a single macro
x86: Make interrupt stack switching atomic
x86: Move NMI back to interrupt stack

The IST is the only thing that requires a valid TSS while running in
kernel mode. Dropping its use unlocks an optimization opportunity for
kvm: if we don't need a valid TSS while in kernel mode we can defer the
use of the VMLOAD/VMSAVE instructions until the next context switch,
reducing the executions of these costly instructions by a nice factor.
Kernel reliability should also be improved since interrupt paths are
simplified.

Instead of scattering the logic around, move all stack switching logic
into a single macro which calls a caller-supplied logic.
This makes changing the logic easier and improves readability.

Instead of relying on pda.irqcount to tell us whether we're already in an
interrupt or not, examine the stack pointer directly. This makes the switch
atomic (since there's no window between incrementing the counter and
switching the stack where an NMI could see the new counter but the old stack),
and lets us get rid of a variable.

Now that interrupt stack switching is atomic, we can move the NMI handler
to the interrupt stack.

applied to tip/x86/irq, thanks Avi!
They have the following commit IDs, and they are also in tip/master:
921e521: x86: move NMI back to interrupt stack
36ef6c9: x86: make interrupt stack switching atomic
dd64891: x86: consolidate irq stack switching to a single macro
955a368: x86: drop the use of the tss interrupt stack table (IST)
I also started testing them in tip-qa.
I added the standard Impact-lines that we do in the x86 tree. Note that
this patch:
dd64891: x86: consolidate irq stack switching to a single macro
isnt just consolidating IRQ entry assembly code, it is also changing the
paranoidentry macros to do IRQ stack entries - and hence switches all but
the NMI critical exception entries sequences over to the IRQ stack. Your
later patch:
921e521: x86: move NMI back to interrupt stack
covers the NMI entry code too.
Please double-check that we indeed now have all the critical exceptions on
the IRQ stack (they are all rare so testing alone wont show this), and
please also double-check that we dont have more exceptions and entry
callpaths on the IRQ stack than what we wanted. For example on a
preemptible kernel (or in any codepath that calls schedule()) it is fatal
to be on the IRQ stack, so this has to be very accurately coded.

testing failed quickly, the attached config crashes. I've pushed out the
bad kernel to the tip/tmp.master.bad branch:
fe3aac9: Merge branch 'x86/irq'
(no crashlog available - all i know that the box crashed and rebooted,
when booted with the bzImage built out of the attached config.)
