f327fee4ca Fix KTROP_CLEARFILE so it does the same thing as KTROP_CLEAR (i.e. vrele()
rather than vn_close()).  Fixes PR 5357.

82eb51ee05 In soshutdown(), decouple the evaluation of the `how' argument from FREAD
and FWRITE; use SHUT_{RD,WR,RDWR} instead.
Also, return EINVAL if `how' is invalid.

7a239c12c6 In vfs_unmountall(), if curproc is NULL, abort, because unmounting
puts the requesting process to sleep until the file systems buffers
have flushed, and sleeping with a NULL curproc will cause a fault.

2018d40811 Allocate kernel virtual address space for the U-area before allocating
the new proc structure when performing a fork.  This makes it much
easier to abort a fork operation and return an error if we run out
of KVA space.

The U-area pages are still wired down in {,u}vm_fork(), as before.

3a1500efe9 Per X/Open CAE Spec Issue 5 Version 2, change the buffer size argument of
readlink() from type `int' to type `size_t'.  This isn't an ABI change, since
the calling convention of our only LP64 platform (the Alpha) already promotes
this argument to a `long'.

This may not be the final action on this matter; readlink() still returns
an `int', which may change in a future revision of the standard.

b436157e65 Make proc0 use the statically-allocate vmspace0 again, and make it use
the kernel's pmap, since proc0 (and other that share its address space)
are kernel-only processes, and should never contain userspace mappings.

This makes it easier to detect errors, like entering user mappings
for kernel processes, in pmap modules, and makes some sense, considering
that kernel processes are really just "thread contexts" for the kernel.

272d8a4a38 Process 2 (the pagedaemon) always runs in kernel space, so share VM

071ab13ebb Move the permission check in change_owner() back to ufs_vnops::ufs_chown()
again - the facility required in this context would be a filesystem-specific
super-user determination, which is not available yet.  Also, add some
clarification to a comment.

6c57a3c322 Change vfs_opv_init_explicit() to not allocate the vnode operations
vectors; defer that to vfs_opv_init().

Change the interface to vfs_opv_init() and export it; it now takes a
pointer to an array of vnodeopv_desc *'s to initialize.  Allocate
the vnode operations vectors here.  Called by vfs_attach().

Implement vfs_opv_free(), which deallocates the vnode operations
vectors.  Called by vfs_detach().

Change vfsinit() to build the initial vfs_list by traversing the
vfs_list_inital[] table, and vfs_attach()'ing those file systems.
Also, initialize special vnodeopv_descs (dead, fifo, spec) which
are not associated with any particular file system.

3ef309317a * Factor out some permission-checking code from ufs_setattr() into
change_owner().
* Change the semantics of chown(), fchown() and lchown(): when requesting a
  change of the owner of a file, clear the set-user-id bit; analogous behaviour
  for group changes.
* Since the above is a violation of the semantics specified by POSIX and
  X/Open, add corresponding compatibility syscalls: __posix_chown(),
  __posix_fchown(), __posix_lchown().  (Neither fchown() nor lchown() is
  specified by POSIX; the prefix is intended to reflect the semantics.)
* Rename posix_rename() to __posix_rename() to follow the above convention.
