target-i386: Fix "call im" on x86_64 when executing 32-bit code

Similarly to what is done in 32938e127f50a40844a0fb9c5abb8691aeeccf7e
for "jmp im", trunc the immediate to 32-bit when not running in 64-bit
mode.

Revert "kvm: x86: Save/restore exception_index"

This reverts commit ebbc8a3d8e76d0402f8a08c10c0f32e24715d41d.

As suggested by Jan Kiszka,

"It was obsoleted by d1793b836f8f123b961c613de1bb1c0c185c84cc and now
   saves/restores a useless field."

kvm: x86: Use separate exception_injected CPUState field

Marcelo correctly remarked that there are usage conflicts between QEMU
core code and KVM /wrt exception_index. So spend a separate field and
also save/restore it properly.

target-i386: Update CPUID feature set for TCG

The CPUID features QEMU presented to the guest were not up-to-date
with QEMU's emulated feature set.
Add the missing bits of recent (and not so recent) additions to
QEMU's emulation engine.
For stability reasons only the user mode usable bits are exposed for...

v2: properly save kvm system time msr registers

Currently, the msrs involved in setting up pvclock are not saved over
migration and/or save/restore. This patch puts their value in special
fields in our CPUState, and deal with them using vmstate.

kvm also has to account for it, by including them in the msr list...

kvm: x86: Save/restore exception_index

As KVM now makes use of exception_index to keep pending exceptions, we
have to save&restore this field as well.

NOTE: We have to nail the arch-independent exception_index down to a
certain bit width for proper vmstate processing, namely to 32 bit....

cpuid: Fix multicore setup on Intel

The multicore CPUID code detects whether the guest is an Intel or an
AMD CPU, because the Linux kernel is picky about the CmpLegacy bit.
KVM by default passes through the host's vendor, which was not
catched by the code. So fork out the vendor determining bits into a...

kvm: x86: Fix initial kvm_has_msr_star

KVM_GET_MSR_INDEX_LIST returns -E2BIG when the provided space is too
small for all MSRs. But this is precisely the error we trigger with the
initial request in order to obtain that size. Do not fail in that case.

This caused a subtle corruption of the guest state as MSR_STAR was not...
