9a0aea4625 Change i_gen in UFS to an unsigned type.
Revert the simplification of the i_gen calculation.
It is still a good idea to avoid zero values and for the case
of old filesystems there is probably no advantage in using
the complete 32 bits anyways.

sbin/devd/devd.cc
        All output will now go to syslog(3) if devd is daemonized, or stderr
        if it's running in the foreground.

        Remove the "-D" flag.  Filtering messages by priority now
	happens in the usual syslog way.  For performance reasons, a few
	extra-verbose debugging statements are now conditional on the "-d" (do

5dd4da9f24 Remove forced timeout of in-flight commands from mfi_timeout.
While this prevents commands getting stuck forever there is no way to guarantee
that data from the command hasn't been committed to the device.

In addition older mfi firmware has a bug that would cause the controller to
frequently stall IO for over our timeout value, which when combined with
a forced timeout often resulted in panics in UFS; which would otherwise be
avoided when the command eventually completed if left alone.

For reference this timeout issue is resolved in Dell FW package 21.2.1-0000.
Fixed FW package version for none Dell controller will likely vary.

3d4b80da4e __weak_alias() doesn't exist on FreeBSD. Use __weak_reference();
Expose iconv functions as weak symbols as well as their internal
remapped #define names.  This is necessary for autoconf compatability -
on Linux it appears that #include <iconv.h> isn't a link time
prerequisite for their version that's built into glibc.

Initialize the pthread rwlock.  Note that upstream has three
separate locks.  The file-local static lock appears intentional.

I'm using this as a ports-compatible compile-time substitute for
converters/libiconv on one of my personal machines.

eee4072f13 Change i_gen in UFS to an unsigned type.
In UFS, i_gen is a random generated value and there is not way for
it to be negative. Actually, the value of i_gen is just used to
match bit patterns and it is of not consequence if the values are
signed or not.

Following other filesystems, set it to unsigned and use it as such,

70a7dd5d5b Fix issues with zeroing and fetching the counters, on x86 and ppc64.
Issues were noted by Bruce Evans and are present on all architectures.

On i386, a counter fetch should use atomic read of 64bit value,
otherwise carry from the increment on other CPU could be lost for the
given fetch, making error of 2^32.  If 64bit read (cmpxchg8b) is not
available on the machine, it cannot be SMP and it is enough to disable
preemption around read to avoid the split read.

On x86 the counter increment is not atomic on purpose, which makes it
possible for the store of the incremented result to override just
zeroed per-cpu slot.  The effect would be a counter going off by
arbitrary value after zeroing.  Perform the counter zeroing on the
same processor which does the increments, making the operations
mutually exclusive.  On i386, same as for the fetching, if the
cmpxchg8b is not available, machine is not SMP and we disable
preemption for zeroing.

PowerPC64 is treated the same as amd64.

For other architectures, the changes made to allow the compilation to
succeed, without fixing the issues with zeroing or fetching.  It
should be possible to handle them by using the 64bit loads and stores
atomic WRT preemption (assuming the architectures also converted from
using critical sections to proper asm).  If architecture does not
provide the facility, using global (spin) mutex would be non-optimal
but working solution.

70f536371e Make atomic_fetch_add() and atomic_fetch_sub() work for pointers with GCC 4.2.
According to the standard, atomic_fetch_*() has to behave identical to
regular arithmetic. This means that for pointer types, we have to apply
the stride when doing addition/subtraction.

The GCC documentation seems to imply this is done for __sync_*() as
well. Unfortunately, both tests and Googling seems to reveal this is not
really the case. Fix this by performing the multiplication with the
stride manually.
