In virtqueue_{split,packed}_get_avail_bytes() descriptors are read
in a loop via MemoryRegionCache regions and calls to
vring_{split,packed}_desc_read() - these take a region cache and the
index of the descriptor to be read.
For direct descriptors we use a cache provided by the caller, whose

Doesn't need any modification in read_mstatus.
It just returns whatever is in the mstatus.

TCG code-gen would be different depending on whether ubcfi is enabled or not.
As an example a TB might have code generated when bcfi was enabled.

Yes, please.
By default, the backing shmem file for a restrictedmem fd is created
on shmem's kernel space mount.
With this patch, an optional tmpfs mount can be specified, which will
be used as the mountpoint for backing the shmem file associated with a
restrictedmem fd.
This change is modeled after how sys_o
Hello,
This patchset builds upon the memfd_restricted() system call that has
been discussed in the ‘KVM: mm: fd-based approach for supporting KVM’

For memfd_restricted() calls without a userspace mount, the backing
file should be the shmem mount in the kernel, and the size of backing
pages should be as defined by system-wide shmem configuration.
If a userspace mount is provided, the size of backing pages should be
as defined in the mount.
