2f6e6e9b4c Correct the displayed bandwidth calculation for a readout via sysctl. The
saved value does not have to be scaled with HZ; it is already in bytes per
second.  Only the multiply by eight remains to show bits per second (bps).

3a00930042 In set_regs(), flush the dirty registers onto the backingstore before
we update the registers. That way we don't have any dirty registers to
worry about and also know that bsp=bspstore, which makes updating the
RSE related registers predictable.
This is not the end of it. We need more validity checks, but for now
this allows us to complete the gdb testsuite without crashing the
kernel.

1510469e95 Mark USB ethernet devices as IFF_NEEDSGIANT, since the USB framework
if_start routines cannot currently be entered without Giant.  When
the kernel is running with debug.mpsafenet != 0, this will defer
if_start execution to a task queue thread holding Giant, which may
introduce additional latency, but avoid incorrect execution.

38c9c1708b Perform a lockless read to test whether an entropy havesting fifo is
full, avoiding the cost of mutex operations if it is.  We re-test
once the mutex is acquired to make sure it's still true before doing
the -modify-write part of the read-modify-write.  Note that due to
the maximum fifo depth being pretty deep, this is unlikely to improve
harvesting performance yet.

4da47b2fec Add __elfN(dump_thread). This function is called from __elfN(coredump)
to allow dumping per-thread machine specific notes. On ia64 we use this
function to flush the dirty registers onto the backingstore before we
write out the PRSTATUS notes.

b505f47bef Add ADAPTIVE_GIANT to GENERIC on i386, with the intent of making it
a standard configuration similar to [NO_]ADAPTIVE_MUTEXES.  This
feature causes Giant to be included in the set of mutexes adaptively
spun on.  It appears to have a positive effect on performance on SMP
across several workloads, including measurements of a 16% improvement
on buildworld, and 30%+ improvement for MySQL using the supersmack
benchmark with Giant over the network stack; a 6% improvement without
Giant on the network stack (as a result of less giant contention).

87e83e7d4c In v_addpollinfo(), we allocate storage to back vp->v_pollinfo. However,
we may sleep when doing so; check that we didn't race with another thread
allocating storage for the vnode after allocation is made to a local
pointer, and only update the vnode pointer if it's still NULL.  Otherwise,
accept that another thread got there first, and release the local storage.

39dfb406e1 Modify vnode locking key: the v_pollinfo pointer itself is protected
by Giant; the contents are protected by the pollinfo mutex.  We rely
on Giant to prevent races in assigning the value of v_pollinfo.

4ffa3fef69 Fix one of the lastest commit. This bio_caller1 should also be changed to
bio_driver1 (as all the rest).
This introduced a small memory leak, but it wasn't really critical,
because maximum memory for g_stripe_zone is always set, so after few
requests gstripe was working in "economic" mode.
