When spa retry load succeeds and spa recovery is requested it may
leak in spa_load_best function.  Always free the generated config
when it is not assigned to the spa.

Currently boot parameters (r0 - r3) are forgotten in ARM trampoline code.
This patch save them at startup and restore them before jumping into kernel
_start() routine.
This is usefull when booting with Linux ABI and/or custom bootloader.

Such processes are stopped synchronously by a direct call to
ptracestop(SIGTRAP) upon exec. P2_PTRACE_FSTP causes the exec()ing thread
to suspend itself while waiting for a SIGSTOP that never arrives.

Specifically, the FW_PORT_CMD may or may not work for a VF (the PF
driver can choose whether or not to permit access to this command),
so don't attempt to fetch port information on a VF if permission is
denied by the PF.

Now that we've switched over to using the vDSO on CloudABI, it becomes a
lot easier for us to phase out old features. System call numbering is no
longer something that's part of the ABI. It's fully based on names. As
long as the numbering used by the kernel and the vDSO is consistent
(which it always is), it's all right.

Let's put this to the test by removing a system call (thread_tcb_set())
that's already unused for quite some time now, but was only left intact
to serve as a placeholder. Sync in the new system call table that uses
alphabetic sorting of system calls.

- Avoid double use of "request" in a single sentence.  Instead, describe
  aio_sigevent as being used to request notification of the associated
  operation's completion.  This matches the language used to describe
  aio_sigevent in aio(4).
- Simplify the prohibition on modifying buffers while requests are in
  flight.
- Fix case mismatch.
- Drop note about not using stack variables. C programmers should be able
  to figure out if a stack variable is safe based on the later warning
  about the life cycle requirements of control blocks.
- Remove prohibition on modifying the I/O buffer for aio_fsync() since
  it does not use an I/O buffer.  For aio_mlock(), prohibit modifications
  to the mapping (e.g. due to mprotect, munmap, mmap, etc.) but do not
  prohibit modifications to the memory backing the buffer (stores into
  the pages backing the buffer).

When DEBUG_KMEM_TRACKING is enabled in SPL, we keep tracking all
the buffers alloced by kmem_alloc() and kmem_zalloc().  If a NULL
pointer which indicates no track info in SPL is passed to
spl_kmem_free_track, we just ignore it.
