  target/i386: kvm: add support for TSC scaling

Linux 5.14 will add support for nested TSC scaling.  Add the
corresponding feature in QEMU; to keep support for existing kernels,
do not add it to any processor yet.

The handling of the VMCS enumeration MSR is ugly; once we have more than
one case, we may want to add a table to check VMX features against.

  KVM: Fix dirty ring mmap incorrect size due to renaming accident

Found this when I wanted to try the per-vcpu dirty rate series out, then I
found that it's not really working and it can quickly hang death a guest.  I
found strange errors (e.g. guest crash after migration) happens even without
the per-vcpu dirty rate series.

When merging dirty ring, probably no one notice that the trivial renaming diff
[1] missed two existing references of kvm_dirty_ring_sizes; they do matter
since otherwise we'll mmap() a shorter range of memory after the renaming.

I think it didn't SIGBUS for me easily simply because some other stuff within
qemu mmap()ed right after the dirty rings (e.g. when testing 4096 slots, it
aligned with one small page on x86), so when we access the rings we've been
reading/writting to random memory elsewhere of qemu.

Fix the two sizes when map/unmap the shared dirty gfn memory.

Even though it was only called for devices that have bs->sg set (which
must be character devices), sg_get_max_segments looked at /sys/dev/block
which only works for block devices.

On Linux the sg driver has its own way to provide the maximum number of
iovecs in a scatter/gather list, so add support for it.  The block device
path is kept because it will be reinstated in the next patches.

  scsi-generic: pass max_segments via max_iov field in BlockLimits

I/O to a disk via read/write is not limited by the number of segments allowed
by the host adapter; the kernel can split requests if needed, and the limit
imposed by the host adapter can be very low (256k or so) to avoid that SG_IO
returns EINVAL if memory is heavily fragmented.

Since this value is only interesting for SG_IO-based I/O, do not include
it in the max_transfer and only take it into account when patching the
block limits VPD page in the scsi-generic device.

  block-backend: align max_transfer to request alignment

Block device requests must be aligned to bs->bl.request_alignment.
It makes sense for drivers to align bs->bl.max_transfer the same
way; however when there is no specified limit, blk_get_max_transfer
just returns INT_MAX.  Since the contract of the function does not
specify that INT_MAX means "no maximum", just align the outcome
of the function (whether INT_MAX or bs->bl.max_transfer) before
returning it.

  block: add max_hw_transfer to BlockLimits

For block host devices, I/O can happen through either the kernel file
descriptor I/O system calls (preadv/pwritev, io_submit, io_uring)
or the SCSI passthrough ioctl SG_IO.

In the latter case, the size of each transfer can be limited by the
HBA, while for file descriptor I/O the kernel is able to split and
merge I/O in smaller pieces as needed.  Applying the HBA limits to
file descriptor I/O results in more system calls and suboptimal
performance, so this patch splits the max_transfer limit in two:
max_transfer remains valid and is used in general, while max_hw_transfer
is limited to the maximum hardware size.  max_hw_transfer can then be
included by the scsi-generic driver in the block limits page, to ensure
that the stricter hardware limit is used.

  file-posix: try BLKSECTGET on block devices too, do not round to power of 2

bs->sg is only true for character devices, but block devices can also
be used with scsi-block and scsi-generic.  Unfortunately BLKSECTGET
returns bytes in an int for /dev/sgN devices, and sectors in a short
for block devices, so account for that in the code.

The maximum transfer also need not be a power of 2 (for example I have
seen disks with 1280 KiB maximum transfer) so there's no need to pass
the result through pow2floor.

  machine: move common smp_parse code to caller

Most of smp_parse and pc_smp_parse is guarded by an "if (opts)"
conditional, and the rest is common to both function.  Move the
conditional and the common code to the caller, machine_smp_parse.

Move the replay_add_blocker call after all errors are checked for.

  machine: add error propagation to mc->smp_parse

Clean up the smp_parse functions to use Error** instead of exiting.

  Log Message:
  -----------
  machine: pass QAPI struct to mc->smp_parse

As part of converting -smp to a property with a QAPI type, define
the struct and use it to do the actual parsing.  machine_smp_parse
takes care of doing the QemuOpts->QAPI conversion by hand, for now.
