labeled iretq instruction.
Suppose that multithreaded process executes two threads, currently
scheduled on different processors. Let assume that thread A executes
using %cs or %ss pointing into the descriptor from LDT. If IPI comes
which handler does not return by jump to doreti, and meantime thread B
invalidates descriptor pointed to by %cs or %ss, then iretq from IPI
handler could fault.
Routing the return by doreti_iret allows kernel to catch the situation
and recover from it by sending signal to the usermode.

frame upon segment register load fault. The doreti procedure does not
load segment registers when returning to the kernel frame, and current
values in the segment descriptor cache already allow the kernel mode
to run, not modified by faulted loaded.

These are git commits 36f0fa8fcbc8c7b2b194addd29100fb40e73e4e9 and
d6d06ff5c2ea0fa44becc5ef4340e5f2f15073e4 in dash.
Because this is the first code I'm importing from dash to expand.c, add the
Herbert Xu copyright notice which is in dash's expand.c.
When pathname expanding *\/, the CTLESC representing the quoted state was
erroneously taken as part of the * pathname component. This CTLESC was then
seen by the pattern matching code as escaping the '\0' terminating the
string.
The code is slightly different because dash converts the CTLESC characters
to backslashes and removes all the other CTL* characters to allow
substituting glob(3).
The effect of the bug was also slightly different from dash (where nothing
matched at all). Because a CTLESC can escape a '\0' in some way, whether
files were included despite the bug depended on memory that should not be
read. In particular, on many machines /*\/ expanded to a strict subset of
what /*/ expanded to.
Example:
echo /*"/null"
This should print /dev/null, not /*/null.

ZFS still like to open all vdevs, close them and open them again,
which in turn provokes taste traffic anyway.
I don't know of any clean way to fix it, so do it the hard way - if we can't
open provider for writing just retry 5 times with 0.5 pauses. This should
elimitate accidental races caused by other classes tasting providers created on
top of our vdevs.

That breaks several output, where the most notable is textdump output.
Fix this by having configurable callbacks passed to witness_list_locks()
and witness_display_spinlock() for printing out datas.

hardware tag insertion/stripping. Remove conditional code that
disables these hardware features on SiS190. Also nuke RX fixup code
which is no more required on strict-alignment architectures because
SiS190 supports RX 10 bytes padding.
Now all hardware features except jumbo frame and WOL are supported.
Thanks to Masa Murayama who confirmed SiS190 also has the same
hardware features of SiS191.
I guess the only difference between SiS191 and SiS190 would be
jumbo frame support. It will be implemented in near future.
fragmentation of mbuf chain to 32 from 16 because TSO can send 64KB
sized packet which in turn requires long list of mbuf chain. Due to
lack of documentation, I'm not sure whether driver have to pull up
ethernet/IP/TCP header with options to make controller work but
driver have to parse TCP header to update pseudo TCP checksum
anyway. The controller expects pseudo TCP checksum computed by
upper stack and the checksum should follow the MS NDIS
specification to make TSO work.
