temporary workaround. This fixes zfs booting generally, but breaks all
GELI booting by default. Add note to UPDATING to this effect. When the
GELI issues are resolved, this will be reverted.
We need to include ficl.h after the standard includes, rather than
before them. It changes the generated code in ways that haven't been
completely analyized. This restores the old code generation (as
verified by md5 changing back for zfsloader).
This should restore GPT + ZFS and GPT + ZFS + GELI booting that was
broken in r326585 (or would have been if r326584 hadn't broken the
build).

dvp->v_mount after dvp is unlocked.
The vnode might be reclaimed after unlock, so v_mount becomes NULL.
Cache the struct mount pointer before the unlock, the struct is
type-stable.
Note that devfs_allocv() reads mp->mnt_data but does not operate on it
further when dirent is doomed. The unmount cannot proceed until all
dirents are reclaimed.

- Add the BCM4322X D11 core revision and missing BCM43224 PCI device ID to
our device tables.
- Disable the DMA engine parity check (rather than adding parity support
to the to-be-replaced bwn(4) DMA implementation).
Currently, N-PHY support in bwn(4) is GPL licensed, and is not included by
default. Until this is replaced with Broadcom's ISC-licensed N-PHY
implementation, bwn(4) must be rebuilt to enable N-PHY support.
To build bwn(4) with N-PHY support, add the following lines to your kernel
configuration file and rebuild the kernel (and modules):
options BWN_GPL_PHY
To test bwn(4) with a BCM43224/BCM43225 device, install the firmware from
the net/bwn-firmware-kmod port, and place the following lines in
loader.conf(5):
hw.bwn_pci.preferred="1"
if_bwn_pci_load="YES
bwn_v4_ucode_load="YES"
bwn_v4_n_ucode_load="YES"
bwn_v4_lp_ucode_load="YES"

Official Linux dts's put the individual portals under a simple-bus, rather
than under a '*-portals' grouping. This adds a hack to permit that, which
gets us closer to using stock device trees for DPAA-based devices.
- The window target must always be updated when stealing a register window.
- Fix missing initialization of bhndb(4) region alloc_flags when
registering statically mapped port regions (caught by scan-build).

Don't create a dummy __tls_get_addr.
We just don't need one with the current setup.
We only error on undefined references that are used by some
relocation.
If we managed to relax all uses of __tls_get_addr, no relocation uses
it and we don't produce an error.
This is less code and fixes the case were we fail to relax. Before we
would produce a broken output, but now we produce an error.
Pull in r320390 from upstream lld trunk (by Rafael Espindola):
Create reserved symbols early so they can be versioned.
This fixes pr35570.
We were creating these symbols after parsing version scripts, so they
could not be versioned.
We cannot move the version script parsing later because we need it for
lto.
One option is to move both addReservedSymbols and
createSyntheticSections earlier. The disadvantage is that some
sections created by createSyntheticSections replace other input
sections. For example, gdb index replaces .debug_gnu_pubnames, so it
wants to run after gc sections so that it can set S->Live to false.
What this patch does instead is to move just the ElfHeader creation
early.
Pull in r320412 from upstream lld trunk (by Rafael Espindola):
Handle symbols pointing to output sections.
Now that gc sections runs after linker defined symbols are added it
can see symbols that point to an OutputSection.
Should fix a bot failure.
Pull in r320431 from upstream lld trunk (by Peter Collingbourne):
ELF: Do not follow relocation edges to output sections during GC.
This fixes an assertion error introduced by r320390.

g_mirror_event_send() acquires the I/O queue lock to deliver a wakeup
to the worker thread, and this is done after enqueuing the event.
So it's sufficient to check the event queue before atomically releasing
the queue lock and going to sleep.

There are two versions of variant I of TLS
- ARM and aarch64 uses original version of variant I here TP points to
start of TCB followed by aligned TLS segment. Both TCB and TLS must
be aligned to alignment of TLS section. The TCB[0] points to DTV vector
and DTV values are real addresses (without bias).
- MIPS, PowerPC and RISC-V use modified version of variant I,
where TP points (with bias) to TLS and TCB immediately precedes TLS
without any alignment gap. Only TLS should be aligned. The TCB[0]
points to DTV vector and DTV values are biased by constant value (0x8000)
from real addresses.
Take all this in account when allocating memory for TLS structures.
