40e19b519c KVM: SVM: Get rid of x86_intercept_map::valid
By reserving 0 as an invalid x86_intercept_stage, we no longer
need to store a valid flag in x86_intercept_map.

a78484c60e KVM: MMU: Make cmpxchg_gpte aware of nesting too
This patch makes the cmpxchg_gpte() function aware of the
difference between l1-gfns and l2-gfns when nested
virtualization is in use.  This fixes a potential
data-corruption problem in the l1-guest and makes the code
work correct (at least as correct as the hardware which is
emulated in this code) again.

107e0e0cd8 x86, apic: Introduce .apicdrivers section to find the list of apic drivers
This will pave the way for each apic driver to be self-contained
and eliminate the need for apic_probe[].

Order in which apic drivers are listed in the .apicdrivers
section is important, as this determines the apic probe order.
And this is enforced by the ordering of apic driver files in the
Makefile and the macros apic_driver()/apic_drivers().

writes "(null)" to driver name string in struct snd_card if card->driver_name

Fix this by using the card->name if no driver name is specified.
