5d2bff060a Make sure all cached buffers with valid, not yet written data have been 
run through copy-on-write.  Call fscow_run() with valid data where possible.

The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against
endless recursion.

- Add a flag B_MODIFY to bread(), breada() and breadn().  If set the caller
  intends to modify the buffer returned.

- Always run copy-on-write on buffers returned from ffs_balloc().

- Add new function ffs_getblk() that gets a buffer, assigns a new blkno,
  may clear the buffer and runs copy-on-write.  Process possible errors
  from getblk() or fscow_run().  Part of PR kern/38664.

Welcome to 4.99.63

961a5d4bcb Fscow_run() may recurse into itself. 
Take care by adding a per-lwp recursion counter.

f703bee5ef Fix two sizeof(__arraycount()) to not use sizeof when looking up the size 
of the array.

This fixes a crash when run on amd phenom under amd64.

848e7ffe8c In prop_data_create_data(blob, len), if len == 0, allocate no memory 
for blob, and leave pd_mutable set to NULL.  In this way, avoid
tripping over the assertion in prop_data_data_nocopy().

f2c43a72d5 VAR_CMD context is used by conditionals and other purposes, so 
actually set VAR_FROM_CMD when appropriate and only skip setting in
VAR_GLOBAL when that flag is set.

e979c658c9 Import writing part of the UDF file system making optical media like CD's 
and DVD's behave like floppy discs. Writing is supported upto and including
version 2.01; version 2.50 and 2.60 will follow.

Also extending the UDF implementation to support symbolic links and
hardlinks.

Added are the mmcformat(8) tool to format rewritable CD/DVD discs and
newfs_udf(8).

Limitations:
        all operations can be performed on the file system though the
        sheduling is currently optimised for archiving workloads.

        mv(1)/rename(2) is currently only implemented for non-directories.

bf1cf71fcd - cpu_attach: ensure that the boot processor is set up before trying to 
initialize APs. We need the lapic set up and the boot processor may
  not be attached first.

- mp_cpu_start: write back and invalidate the data cache before starting the
  init IPI sequence. If a buggy BIOS has left the AP with cache disabled,
  it might not be able to participate in the cache coherency protocol.
