x86/cpuid: Tighten parsing of tsc_freq=FREQ

cpu_x86_find_by_name() uses strtosz_suffix_unit(), but screws up the
error checking. It detects some failures, but not all. Undetected
failures result in a zero tsc_khz value (error value -1 divided by
1000), which means "no tsc_freq set"....

Revert "i386: derive '-cpu host' from KVM_GET_SUPPORTED_CPUID"

This reverts commit 66e3dd9282141b5ae75637c9676002cf3ceeb988.

From Avi,

"Anthony, I think we should revert that commit and refactor cpuid for
  1.1.  The logic is spread over too many places which makes it hard to...

x86: fix pcmpestrm and pcmpistrm

Fix obvious typos (decrement and off-by-one error) in pcmpestrm and pcmpistrm
which resulted in infinite loop. Reported by Frank Mehnert,
spotted also by Coverity (bug 84752853).

Reported-by: Frank Mehnert <>...

i386: derive '-cpu host' from KVM_GET_SUPPORTED_CPUID

The fact that a host cpu supports a feature doesn't mean that QEMU and KVM
will also support it, yet -cpuid host brings host features wholesale.

We need to whitelist each feature separately to make sure we support it....

Fix X86 CPU topology in KVM mode

apic id returned to guest kernel in ebx for cpuid(function=1) depends on
CPUX86State->cpuid_apic_id which gets populated after the cpuid information
is cached in the host kernel. This results in broken CPU topology in guest....
