Before the change it wasn't possible and the following error was printed:
ZFS: can only boot from disk, mirror or raidz vdevs
Now if the original vdev (the one we are replacing) is still present we will
read from it, but if it is not present we won't read from the new vdev, as it
might not have enough valid data yet.

objects inside one ELF section, which prevents the creation of a ELF
section with mixed data types. For example, gcc LTO use libelf to
create a .gnu_lto_XXX section that contains integers and a string
table, which doesn't work with our libelf implementation.
The changes made in this commit include:
* Allow Elf_Data type to be different than section type.
* Relax Elf_Data alignment check.
* Align each Elf_Data by their own alignment instead of section alignment.

FIXEDLEN buffer.
Note that some sysctl handlers were explicitly outputting a trailing NUL
byte. This behaviour was preserved, though it should not be necessary.

called when the sbuf internal buffer is filled. For kernel sbufs with a
drain, the internal buffer will never be expanded. For userland sbufs
with a drain, the internal buffer may still be expanded by
sbuf_[v]printf(3).
Sbufs now have three basic uses:
1) static string manipulation. Overflow is marked.
2) dynamic string manipulation. Overflow triggers string growth.
3) drained string manipulation. Overflow triggers draining.
In all cases the manipulation is 'safe' in that overflow is detected and
managed.

- Provide 64 bit implementations for some macros. On n64 and n32,
don't split 64 bit values.
- No need for 32 bit ops for control registers.
- Fix few bugs (write control reg, write_c0_register64).
- Re-write EIRR/EIMR/CPUID operations using read_c0_registerXX, no
need of inline assembly.
- rename control reg access functions to avoid phnx, update callers.

NFSv2,3 byte range locking is attempted. A fix that allows the

pmap_remove() from vm_pageout_map_deactivate_pages() with the entire range
of the map could result in attempting to demap an extraordinary number
of pages (> 10^15), so iterate through each map entry and unmap each of
them individually.

K2 SATA controllers. The chip's status register must be read first, and
as a long, for other registers to be correctly updated after a command, and
this includes the command sequence in device detection as well as the
previously handled case after interrupts. While here, clean up some
previous hacks related to this controller.

- Correct error paths. The system will be useless on devfs_fixup() failure, so
why bother? Maybe for the same reason why a dead body is washed and dressed
in a nice suit before it is put into a coffin? Maybe system's last will is to

- Fix freeing mbufs in case of P2P descriptors:
We cannot free the mbuf when the P2P descriptor freeback is received. The
mbuf may be still in use by the GMAC, since the P2P freeback indicates that
it read the P2D descriptors in the P2P message.
Now we free just the P2P descriptor when the P2P freeback message is
received. Another freeback P2D message has been added to the end of
the packet descriptors, the mbuf will be freed only when we received
this.
The P2P descriptor issue was reported by srgorti at netlogicmicro dot com.
