x86: fix delta calculation in TSC deadline timer emulation
In the virtual LAPIC, correct the delta calculation when emulating the
TSC deadline timer.
Without this fix, XenServer (which is based on Xen 4.1) does not work
when running as an HVM guest. dom0 fails to boot because its timer
interrupts are very delayed (by several minutes in some cases).

Fix save/restore of guest PAT table in HAP paging mode.
HAP paging mode guests use direct MSR read/write into the VMCS/VMCB
for the guest PAT table, while the current save/restore code was
accessing only the pat_cr field in hvm_vcpu, used when intercepting
the MSR mostly in shadow mode (the Intel scenario is a bit more
complicated). This patch fixes this issue creating a new couple of
hvm_funcs, get/set_guest_pat, that access the right PAT table based on
the paging mode and guest configuration.

x86-64: fix #GP generation in assembly code
When guest use of sysenter (64-bit PV guest) or syscall (32-bit PV
guest) gets converted into a GP fault (due to no callback having got
registered), we must
- honor the GP fault handler's request the keep enabled or mask event
delivery
- not allow TBF_EXCEPTION to remain set past the generation of the
(guest) exception in the vCPU's trap_bounce.flags, as that would
otherwise allow for the next exception occurring in guest mode,
should it happen to get handled in Xen itself, to nevertheless get
bounced to the guest kernel.
Also, just like compat mode syscall handling already did, native mode
sysenter handling should, when converting to #GP, subtract 2 from the
RIP present in the frame so that the guest's GP fault handler would
see the fault pointing to the offending instruction instead of past it.
Finally, since those exception generating code blocks needed to be
modified anyway, convert them to make use of UNLIKELY_{START,END}().

x86-64: Fix memory hotplug epfn upper limit test for updating the compat M2P table
The epfn is being compared to (RDWR_COMPAT_MPT_VIRT_END -
RDWR_COMPAT_MPT_VIRT_START) without a 2 bit shift, resulting in the
epfn being compared to the size of the RDWR_COMPAT_MPT table in bytes
instead of the maximum page frame number that the RDWR_COMPAT_MPT
table can map.

svm: Do not intercept RDTSC(P) when TSC scaling is supported by hardware
When running in TSC_MODE_ALWAYS_EMULATE mode on processors that
support TSC scaling we don't need to intercept RDTSC/RDTSCP

fix vmce MCi_ADDR/MCi_MISC wrmsr bug
This patch fixes a bug related to wrmsr vmce MCi_ADDR/MCi_MISC
registers, since they are not read-only.
Intel SDM recommanded os mce driver clear MCi_ADDR/MCi_MISC, so guest
MCE driver may clear MCi_ADDR/MCi_MISC registers. In such case, old
vmce wrmsr logic would generate a #GP fault in guest MCE context,
causing the guest to crash.
When wrmsr MCi_ADDR/MCi_MISC, writing all 1s will cause #GP.

x86_64: Fix off-by-one error setting up the Interrupt Stack Tables
The Interrupt Stack Table entries in a 64bit TSS are a 1 based data
structure as far as hardware is concerned. As a result, the code
setting up stacks in subarch_percpu_traps_init() fills in the wrong
IST entries.
The result is that the MCE handler executes on the stack set up for
NMIs; the NMI handler executes on a stack set up for Double Faults,
and Double Faults are executed with a stack pointer set to 0.
Once the #DF handler starts to execute, it will usually take a page
fault looking up the address at 0xfffffffffffffff8, which will cause a
triple fault. If a guest has mapped a page in that location, then it
will have some state overwritten, but as the #DF handler always calls
panic(), this is not a problem the guest will have time to care about.
