The "vt_suspend_flush_timer()" function is sometimes called locked
which prevents us from doing a "callout_drain()" call. The callout in
question has a lock associated with it and we are not freeing the
callout. That means we can use the "callout_stop()" function to
atomically stop the callback iff the "callout_stop()" function is
called locked. This patch applies proper locking to "callout_stop()"
and replaces a "callout_drain()" with a "callout_stop()".
The "cnputs_mtx" mutex must be allowed to recurse. Debug prints and/or
witness printouts in the console driver clients can cause this mutex
to recurse by calls to "printf()" from witness for example. In
particular this can happen if "debug.witness.skipspin=0" is set in the
boot environment.
Various XHCI fixes and improvements:
- Improve and fix MSI interrupt allocation, setup and release.
- Add missed flushing of data which can happen when "xhci_configure_mask()"
is called from "xhci_configure_reset_endpoint()". Ensure the 3-strikes
error feature is always enabled except for ISOCHRONOUS transfers.
- Allow systems having a page size greater than 4K to use fewer
scatter-gather XHCI TRB entries for its payload data. The XHCI
controller can handle at least 65536 bytes per scatter-gather list
entry.
Cast *path to silence clang -Wpointer-sign warning.
Indeed, instead of hiding the kern___getcwd() bug by bogus cast
in r276564, change path type to char * (pathnames are always char *).
And remove bogus casts of malloc().
kern___getcwd() internally doesn't actually use or support u_char *
paths, except to copy them to a normal char * path.
These changes are not visible to libc as libc/gen/getcwd.c misdeclares
__getcwd() as taking a plain char * path.
While here remove _SYS_SYSPROTO_H_ for __getcwd() syscall as
we always have sysproto.h.
r276765:
Update pkg-stage.sh to be compatible with pkg-1.4.x.
In 1.3.x and earlier, ABI format is, for example,
freebsd:11:x86:64.
In 1.4.x, ABI format is FreeBSD:11:amd64, and a new
configuration entry, ALTABI, is: freebsd:11:x86:64.
Export PKG_ABI and PKG_ALTABI accordingly, and if
PKG_ALTABI is set, create a symlink within the dvd
PKG_CACHEDIR so both new and old ABI directories
exist.
r276766:
Properly change directories before creating the
PKG_ALTABI -> PKG_ABI symlink.
r276820:
Print informational output when NOPORTS is set,
which would otherwise cause pkg-stage.sh to
silently exit.
r276822:
Ensure /var/run/ld-elf.so.hints exists before building
pkg(8).
r276827:
Ensure the ports directories exist for the list of
packages intended to be included on the DVD, and
remove any nonexistent ports from the final list.
Print the list of missing paths, and ensure that
DVD_PACKAGES is non-zero length (which should never
happen).
r276828:
Switch to x11/gnome3 now that x11/gnome2 no longer
exists in the ports tree.

Fix a panic in zfs_rename().
this is due to a wrong dereference of a vnode when it's not locked and
can be (potentially) recycled. 'sdvp' cannot be locked on zfs_rename()
entry point because the VFS can't be sure that this scenario is
LOR-free (it might violate the parent->child lock acquisition rule).
Dereference 'tdvp' instead, which is already locked on entry, and access
'sdvp' fields only when it's safe, i.e. under ZFS_ENTER scope.
While at it, remove the usage of VOP_REALVP, as long as this is a NOP
on FreeBSD.
Fix the musb initialization sequence on AM335x.
According to http://e2e.ti.com/support/arm/sitara_arm/f/791/t/210729 the
USB reset pulse has an undocumented duration of 200ns and during this
period the module must not be acessed.
We wait for 100us to take into account for some imprecision of the early
DELAY() loop.
This fixes the eventual 'External Non-Linefetch Abort (S)' that happens at
boot while resetting the musb subsystem.
While here, enable the USB subsystem clock before the first access.
Fix cpsw_detach() to not panic when called from cpsw_attach().
For an unkown reason (at moment), sometimes if_cpsw cannot read from PHY
and fails to attach calling cpsw_detach() which end up in a panic.
Fix it by doing the proper check before detach the miibus and also fix the
leak of few variables.
And to actually make it work, ether_ifattach() has to be moved to the end
of cpsw_attach() to avoid a race where calling ether_ifdetach() before
domain_init() (which will only run later on) would make it crash at
INP_INFO_RLOCK() on in_pcbpurgeif0().
Tested on: BBB (am335x)
Fix a bug where DMA maps created with bus_dmamap_create() won't increment
the map count and without being able to keep track of the current map
allocation, bus_dma_tag_destroy() will fail to proceed and will return
EBUSY even after all the maps have been correctly destroyed with
bus_dmamap_destroy().
Found while testing the detach method of a NIC.
Fix a bug where some DTS layouts could cause the premature ending of the
search (i.e. without returning any result) and you would end up with a
random MAC address.
Change the search algorithm to a recursive one to ensure that all the nodes
on DTS will be verified.
The previous algorithm could not keep up if the DTS has too many sub-nodes.
While here, fix the punctuation on comments.
Add an iicbus_reset() method to bcm2835_bsc. While it is generally not
used for kernel devices it is used by i2c(8).
This fix the 'error: Device not configured' when i2c(8) tries to reset the
controller:
# i2c -r
Resetting I2C controller on /dev/iic0: error: Device not configured
For now use conservative settings for default i2c speeds.
Add another wakeup() after actually set the bus as free.
This fix a race where the threads waiting for the bus would wake up early
and still see bus as busy.
While here, give a better description to wmesg for the two use cases we
have (bus and io waiting).
Fix the mtx_sleep() error checking, catch all errors and not only
EWOULDBLOCK.
Do not print any message at errors. The errors are properly sent to upper
layers which should be able to deal with it, including printing the errors
when they need to.
The error message was quite annoying while scanning the i2c bus.
patch: Bring in xstrdup and use it when appropriate.
The function savestr allows NULL return values during Plan A patching so in
case of out of memory conditions, Plan B can step in. In many cases, NULL
value is not properly handled, so use xstrdup here (it's outside Plan A/B
patching, which means that even Plan B relies on successful operations).
Clean up some whitespaces while here

Use CURVNET macros inside inet_get_local_port_range() function.
Without this fix, a kernel with VIMAGE + Infiniband will panic on bootup.
Certain necessary #include statements require LIST_HEAD.
Add these includes to ofed/include/linux/list.h, because
LIST_HEAD is specifically overridden in this file.
