[RISCV] Split LMUL=8 f16 fixed vector (s/u)ittofp/fpto(s/u)i before promoting. (#191568)
The conversion needs to be done by promoting to f32. If we're already at
LMUL=8, we need to split before we can promote.
nfs_nfsdsocket.c: Allow Copy/Clone from a read-only fs
For some server file system types, such as ZFS, a Copy/Clone
operation can be done across file systems of the same file
system type.
However, without this patch, the Copy/Clone will fail with
EROFS if the input file is on a read-only mounted file system.
This happens because Copy/Clone will try to do a VOP_SETATTR()
of atime to set the atime.
This patch pretends the VOP_SETATTR() of atime worked for
read-only file systems. It fixes a problem when copying
files from a ZFS snapshot.

nfs_diskless: Add support for an NFSv4 root fs
Without this patch, diskless root NFS file systems
could only be mounted via NFSv3 (or NFSv2).
This patch adds the basic support needed to mount
a root fs via NFSv4.
At this time, the NFSv4 mount will only work if
the following is done on the NFS server configuration:
- The root directory specified in the "V4:" line in
/etc/exports must be "/". This is needed since the
path to mount must be the same for NFSv3 and NFSv4.
- The NFS server must be configured to do both NFSv3
and NFSv4, since the bootstrap code still uses NFSv3.
- The NFSv4 server must be configured with:
vfs.nfs.enable_uidtostring=1
vfs.nfsd.enable_stringtouid=1
since the NFSv4 root fs cannot be running nfsuserd(8)
when it is booting. (This limitation may be removed

[clang-doc] Avoid merging into default Info types
When merging into arenas, the code assumed that all using a default
constructed info would be safe, since in the merge we replace any
differing data. However, that appears to be a risky assumption, due
to default initialized members participating in comparisons, and
other operations, leading the program to read garbage data in some
cases. Earlier patches added default initializers to these fields,
but we should prefer (which the old code used to do) to just start
with properly initialized and complete data from the start.
This patch updates the remaining Info types to have copy constructors
that support choosing the arena to allocate into. This is already the
strategy used in several places to avoid use after free bugs. Since
the handling is now uniform, we can simplify things a bit at the same
time and extract the cloning operation into a helper, making the logic
very clear.
This should avoid any potential pitfalls or missed cases that resulted
in the errors discover after landing #190054.
