We now cache the core mmu_idx in env->hflags. Rather than recompute
from scratch, extract the field. All of the uses of cpu_mmu_index
within target/arm are within helpers, and env->hflags is always stable
within a translation block from whence helpers are called.

The Cubieboard is a singleboard computer with an Allwinner A10 System-on-Chip [1].
As documented in the Allwinner A10 User Manual V1.5 [2], the SoC has an ARM
Cortex-A8 processor. Currently the Cubieboard machine definition specifies the
ARM Cortex-A9 in its description and as the default CPU.
This patch corrects the Cubieboard machine definition to use the ARM Cortex-A8.
The only user-visible effect is that our textual description of the
machine was wrong, because hw/arm/allwinner-a10.c always creates a
Cortex-A8 CPU regardless of the default value in the MachineClass struct.

The ARMv8.2-TTCNP extension allows an implementation to optimize by
sharing TLB entries between multiple cores, provided that software
declares that it's ready to deal with this by setting a CnP bit in
the TTBRn_ELx. It is mandatory from ARMv8.2 onward.
For QEMU's TLB implementation, sharing TLB entries between different
cores would not really benefit us and would be a lot of work to
implement. So we implement this extension in the "trivial" manner:
we allow the guest to set and read back the CnP bit, but don't change
our behaviour (this is an architecturally valid implementation
choice).
The only code path which looks at the TTBRn_ELx values for the
long-descriptor format where the CnP bit is defined is already doing
enough masking to not get confused when the CnP bit at the bottom of
the register is set, so we can simply add a comment noting why we're
relying on that mask.

Current virtiofsd has problems about xattr operations and
they does not work properly for directory/symlink/special file.
The fundamental cause is that virtiofsd uses openat() + f...xattr()
systemcalls for xattr operation but we should not open symlink/special
file in the daemon. Therefore the function is restricted.
Fix this problem by:
1. during setup of each thread, call unshare(CLONE_FS)
2. in xattr operations (i.e. lo_getxattr), if inode is not a regular
file or directory, use fchdir(proc_loot_fd) + ...xattr() +
fchdir(root.fd) instead of openat() + f...xattr()
(Note: for a regular file/directory openat() + f...xattr()
is still used for performance reason)
With this patch, xfstests generic/062 passes on virtiofs.
This fix is suggested by Miklos Szeredi and Stefan Hajnoczi.
