KVM: Add CONFIG_HAVE_KVM_IRQCHIP
Two KVM archs support irqchips and two don't. Add a Kconfig item to
make selecting between the two models easier.

KVM: Reset PIT irq injection logic when the PIT IRQ is unmasked
While the PIT is masked the guest cannot ack the irq, so the reinject logic
will never allow the interrupt to be injected.
Fix by resetting the reinjection counters on unmask.
Unbreaks Xen.

Subject: gso: Fix support for linear packets
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fdavem%2Fnet-2.6.git;a=commitdiff_plain;h=2f181855a0b3c2b39314944add7b41c15647cf86
gso: Fix support for linear packets
When GRO/frag_list support was added to GSO, I made an error
which broke the support for segmenting linear GSO packets (GSO
packets are normally non-linear in the payload).
These days most of these packets are constructed by the tun
driver, which prefers to allocate linear memory if possible.
This is fixed in the latest kernel, but for 2.6.29 and earlier
it is still the norm.
Therefore this bug causes failures with GSO when used with tun
in 2.6.29.
