Supermicro LCD screen modules seem to not support accessing reports through
the control pipes, but working fine with the interrupt pipes.

The NAND Flash environment consists of several distinct components:
- NAND framework (drivers harness for NAND controllers and NAND chips)
- NAND simulator (NANDsim)
- NAND file system (NAND FS)
- Companion tools and utilities
- Documentation (manual pages)
This work is still experimental. Please use with caution.

The code previously assumed that copyin/copyout did no
address translation and that the device tree blob could
be manipulated in-place (with only a few adjustments for
the ELF loader offset). This isn't possible on all platforms,
so the revised code uses copyout() to copy the device tree
blob into a heap-allocated buffer and then updates the
device tree with copyout(). This isn't ideal, since it
bloats the loader memory usage, but seems the only feasible
approach (short of rewriting all of the fdt manipulation
routines).
8.x code:
- If the lock cannot be acquired immediately unlocks 'bar' vnode
and then locks both vnodes in order.
- wrong vnode type panics from cache_enter_time after calls by
ext2_lookup.
The fix merges the fixes from ufs/ufs_lookup.c.

Entries with zero inode number are considered placeholders by libc and
UFS. Fix remaining uses of VOP_READDIR in kernel: vop_stdvptocnp,
unionfs.

add some more BAR debugging logic.
* Change the definition of ath_debug and ath_softc.sc_debug from
int to uint64_t;
* Change the relevant sysctls;
* Add a new BAR TX debugging field;
* Use this in if_ath_tx.
This has been tested by using the sysctl program, which happily allows
for fields > 32 bits to be configured.
used as a replacement for libgcc on sparc64 would cause a 60% decrease in
performance is wrong. Actually, the performance loss is only marginal and
the huge difference seen was caused by a pilot error comparing libgcc builds
using MALLOC_PRODUCTION with libcompiler_rt builds that did not.
Although I _should_ handle the other errors in various ways (specifically
errors like FILT), treating them as having transmitted successfully
is completely wrong. Here, they'd be counted as successful and the BAW
would be advanced.. but the RX side wouldn't have received them.
The specific errors I've been seeing here are HAL_TXERR_FILT.
This patch does fix the issue - I've tested it using -i 0.001 pings
(enough to start aggregation) and now the behaviour is correct:
* The RX side never sees a "moved window" error, and
* The TX side sends BARs as needed, with the RX side correctly handling
them.

compatible with the sched provider implemented by Solaris and its open-
source derivatives. Full documentation of the sched provider can be found
on Oracle's DTrace wiki pages.
Note that for compatibility with scripts originally written for Solaris,
serveral probes are defined that will never fire. These probes are defined
to fire when Solaris-specific features perform certain actions. As these
features are not present in FreeBSD, the probes can never fire.
Also, I have added a two probes that are not defined in Solaris, lend-pri
and load-change. These probes have been added to make it possible to
collect schedgraph data with DTrace.
Finally, a few probes are defined in Solaris to take a cpuinfo_t *
argument. As it was not immediately clear to me how to translate that to
FreeBSD, currently those probes are passed NULL in place of a cpuinfo_t *.
