2c6d0e01f8 This patch applies one of the two fixes suggested by
zack.kirsch at isilon.com for a race between nfsrv_freeopen()
and nfsrv_getlockfile() in the experimental NFS server that
he found during testing. Although nfsrv_freeopen() holds a
sleep lock on the lock file structure when called with
cansleep != 0, nfsrv_getlockfile() could still search the
list, once it acquired the NFSLOCKSTATE() mutex. I believe
that acquiring the mutex in nfsrv_freeopen() fixes the race.

37fe683250 Fix the NFSVNO_CMPFH() macro in the experimental NFS server so
that it works correctly for ZFS file handles. It is possible to
have two ZFS file handles that differ only in the bytes in the
fid_reserved field of the generic "struct fid" and comparing the
bytes in fid_data didn't catch this case. This patch changes the
macro to compare all bytes of "struct fid".

4d369413e1 Replace sbuf_overflowed() with sbuf_error(), which returns any error
code associated with overflow or with the drain function.  While this
function is not expected to be used often, it produces more information
in the form of an errno that sbuf_overflowed() did.

6a4e245b76 Add bsd.dtrace.mk. This allows userland programs and libraries to
define USDT probes on a provider.d file and then use this new make
infrastructure to build the corresponding header file and object file.

This will only take effect when the user defines WITH_DTRACE when building.

d3c7b9a08a MFp4 (//depot/projects/mps/...)
Bring in a driver for the LSI Logic MPT2 6Gb SAS controllers.

This driver supports basic I/O, and works with SAS and SATA drives and
expanders.

Basic error recovery works (i.e. timeouts and aborts) as well.

Integrated RAID isn't supported yet, and there are some known bugs.

So this isn't ready for production use, but is certainly ready for
testing and additional development.  For the moment, new commits to this
driver should go into the FreeBSD Perforce repository first
(//depot/projects/mps/...) and then get merged into -current once
they've been vetted.

This has only been added to the amd64 GENERIC, since that is the only
architecture I have tested this driver with.

1217a4ead5 sh(1): Remove xrefs for expr(1) and getopt(1).
expr(1) should usually not be used as various forms of parameter expansion
and arithmetic expansion replicate most of its functionality in an easier
way.

getopt(1) should not be used at all in new code. Instead, getopts(1) or
entirely manual parsing should be used.

c42f230131 Allow to boot from a pool within which replacing is in progress.
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.

ea22f625a7 libelf is overly strict about the type and alignment of Elf_Data
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.
