a788260b20 kvm: require KVM_IRQFD for kernel irqchip
KVM_IRQFD was introduced in Linux 2.6.32, and since then it has always been
available on architectures that support an in-kernel interrupt controller.
We can require it unconditionally.

cc5e719e2c kvm: require KVM_CAP_SIGNAL_MSI
This was introduced in KVM in Linux 3.5, we can require it unconditionally
in kvm_irqchip_send_msi().  However, not all architectures have to implement
it so check it only in x86, the only architecture that ever had MSI injection
but not KVM_CAP_SIGNAL_MSI.

ARM uses it to detect the presence of the ITS emulation in the kernel,
introduced in Linux 4.8.  Assume that it's there and possibly fail when
realizing the arm-its-kvm device.

d830054247 target/i386: check CPUID_PAE to determine 36 bit processor address space
PAE mode in x86 supports 36 bit address space. Check the PAE CPUID on the
guest processor and set phys_bits to 36 if PAE feature is set. This is in
addition to checking the presence of PSE36 CPUID feature for setting 36 bit
phys_bits.

e000687f12 target/i386: validate VEX.W for AVX instructions
Instructions in VEX exception class 6 generally look at the value of
VEX.W.  Note that the manual places some instructions incorrectly in
class 4, for example VPERMQ which has no non-VEX encoding and no legacy
SSE analogue.  AMD does a mess of its own, as documented in the comment
that this patch adds.

Most of them are checked for VEX.W=0, and are listed in the manual
(though with an omission) in table 2-16; VPERMQ and VPERMPD check for
VEX.W=1, which is only listed in the instruction description.  Others,
such as VPSRLV, VPSLLV and the FMA3 instructions, use VEX.W to switch
between a 32-bit and 64-bit operation.

Fix more of the class 4/class 6 mismatches, and implement the check for
VEX.W in TCG.

183e6679e3 target/i386: group common checks in the decoding phase
In preparation for adding more similar checks, move the VEX.L=0 check
and several X86_SPECIAL_* checks to a new field, where each bit represent
a common check on unused bits, or a restriction on the processor mode.

Likewise, many SVM intercepts can be checked during the decoding phase,
the main exception being the selective CR0 write, MSR and IOIO intercepts.

e582b629f0 target/i386: implement SHA instructions
The implementation was validated with OpenSSL and with the test vectors in
https://github.com/rust-lang/stdarch/blob/master/crates/core_arch/src/x86/sha.rs.

The instructions provide a ~25% improvement on hashing a 64 MiB file:
runtime goes down from 1.8 seconds to 1.4 seconds; instruction count on
the host goes down from 5.8 billion to 4.8 billion with slightly better
IPC too.  Good job Intel. ;)
