f8e4b4ef49 sysctl(8) should use the CTLTYPE to determine the type of data when
reading.  (This was already done for writing to a sysctl).  This
requires all SYSCTL setups to specify a type.  Most of them are now
checked at compile-time.

Remove SYSCTL_*X* sysctl additions as the print being in hex should be
controlled by the -x flag to sysctl(8).

e225428f27 In linuxolator getdents_common(), it seems there is no reason to loop
if no records where returned by VOP_READDIR(). Readdir implementations
allowed to return 0 records when first record is larger then supplied
buffer. In this case trying to execute VOP_READDIR() again causes the
syscall looping forewer.

The goto was there from the day 1, which goes back to 1995 year.

55aabb7fd1 For architectures not using direct map , and requiring real KVA page for
sf buf allocation, use wakeup() instead of wakeup_one() to notify sf
buffer waiters about free buffer.

sf_buf_alloc() calls msleep(PCATCH) when SFB_CATCH flag was given,
and for simultaneous wakeup and signal delivery, msleep() returns
EINTR/ERESTART despite the thread was selected for wakeup_one(). As
result, we loose a wakeup, and some other waiter will not be woken up.

0d5ccb45d8 sh: Fix signal messages being sent to the wrong file sometimes.
When a foreground job exits on a signal, a message is printed to stdout
about this. The buffer was not flushed after this which could result in the
message being written to the wrong file if the next command was a builtin
and had stdout redirected.

Example:
  sh -c 'kill -9 $$'; : > foo; echo FOO:; cat foo

ed15702f7e Rework RX filter programming by providing separate handler for
DP8381[56] and SiS 900/7016 controllers.  After r212119, sis(4) no
longer reinitializes controller if ALLMULTI/PROMISC was changed.
However, RX filter handling code assumed some bits of the RX filter
is programmed by driver initialization. This caused ALLMULTI/PROMISC
configuration is ignored under certain conditions.
Fix that issue by reprogramming all bits of RX filter register.
While I'm here follow recommended RX filter programming steps
recommended by National DP8381[56] data sheet(RX filter should be
is disabled before programming).

6bd823f334 - Remove some always-true checks (checking for unsigned < 0).
- Only check largs->num against max_ldt_segment on amd64 for I386_SET_LDT
  when descriptors are provided.  Specifically, allow the 'start == 0'
  and 'num == 0' special case used to free all LDT entries that previously
  failed with EINVAL.

db3a488fb0 In order to save instructions the MMU trap handlers assumed that the kernel
TSB is located within the 32-bit address space, which held true as long as
we were using virtual addresses magic-mapped before the location of the
kernel for addressing it. However, with r216803 in place when possible we
address it via its physical address instead, which on machines like Sun Fire
V880 have no physical memory in the 32-bit address space at all requires
to use 64-bit addressing. When using physical addressing it still should
be safe to assume that we can just ignore the lowest 10 bits of the address
as a minor optimization as we did before r216803.

81eee0ebf8 Implement initial jumbo frame support for RTL8168/8111 C/D/E PCIe
GbE controllers. It seems these controllers no longer support
multi-fragmented RX buffers such that driver have to allocate
physically contiguous buffers.

 o Retire RL_FLAG_NOJUMBO flag and introduce RL_FLAG_JUMBOV2 to
   mark controllers that use new jumbo frame scheme.
 o Configure PCIe max read request size to 4096 for standard frames
   and reduce it to 512 for jumbo frames.
 o TSO/checksum offloading is not supported for jumbo frames on
   these controllers. Reflect it to ioctl handler and driver
   initialization.
 o Remove unused rl_stats_no_timeout in softc.
 o Embed a pointer to structure rl_hwrev into softc to keep track
   of controller MTU limitation and remove rl_hwrev in softc since
   that information is available through a pointer to structure
   rl_hwrev.
