6adf19481c The struct file f_advice member is overlaid with the devfs f_cdevpriv
data.  If vnode bypass for devfs file failed, vn_read/vn_write are
called and might try to dereference f_advice.  Limit the accesses to
f_advice to VREG vnodes only, which is the type ensured by
posix_fadvise().

The f_advice for regular files is protected by mtxpool lock.  Recheck
that f_advice is not NULL after lock is taken.

1a2dd035fb When devfs dirent is freed, a vnode might still keep a pointer to it,
apparently.  Interlock and clear the pointer to avoid free memory
dereference.

afa04e4170 sem: Don't free nameinfo that is still in list when open() fails.
This bug could be reproduced easily by calling sem_open() with O_CREAT |
O_EXCL on a semaphore that is already open in the process. The struct
sem_nameinfo would be freed while still in sem_list and later calls to
sem_open() or sem_close() could access freed memory.

1b44593c51 hyperv/stor: Verify returned inquiry data before further dispatching
Windows 10 and Window 2016 will return all zero inquiry data for
non-existing slots.  If we dispatched them, then a lot of useless
(0 sized) disks would be created.  So we verify the returned inquiry
data (valid type, non-empty vendor/product/revision etc.), before
further dispatching.

Minor white space cleanup and wording fix.

1b46803833 [flash] Teach mx25l SPI flash driver to interact with fdt_slicer and geom_flashmap
This teaches the mx25l driver (sys/dev/flash/mx25l.c) to interact with
sys/dev/fdt/fdt_slicer.c and sys/geom/geom_flashmap.c.

This allows systems with SPI flash to benefit from the possibility to define
flash 'slices' via FDT, just the same way that it's currently possible for
CFI and NAND flashes.

Tested:

* Carambola 2, AR9331 + SPI NOR flash

fa7c058bf8 Fix panic on table/table entry delete. The panic could have happened
if more than 64 distinct values had been used.

Table value code uses internal objhash API which requires unique key
  for each object. For value code, pointer to the actual value data
  is used. The actual problem arises from the fact that 'actual' e.g.
  runtime data is stored in array and that array is auto-growing. There is
  special hook (update_tvalue() function) which is used to update the pointers
  after the change. For some reason, object 'key' was not updated.
  Fix this by adding update code to the update_tvalue().
