The suspension counter needs synchronisation through slock, but we don't
need it to check if inspecting the counter is necessary to begin with.
In the common case it is not, thus avoid the lock if possible.

rather than relying on a set of canned EARLY_DRIVER_MODULE() statements in
the ofw_iicbus source. This means hw drivers will no longer be required to
use one of a few predefined driver names. They will also now be able to
decide themselves if they want to use DRIVER_MODULE or EARLY_DRIVER_MODULE
and to set which pass to attach on for early modules.
Mainly, this adds extern declarations for the driver and devclass variables.
It also renames ofwiicbus_devclass to ofw_iicbus_devclass to be consistant
with the way we use ofw_ prefixes on this stuff.
The description of kern.ipc.shmsegs was wrong since 2005. I updated the
others (which were more correct) to match.

Such items may be allocated in the I/O path used by the dumper,
potentially causing the dump to fail. Since there is some precedent
in the DMAR driver for avoiding this problem using _NODUMP, apply
this workaround to the zone as well.

zdb(8) is full of minor problems that generate compiler warnings. On FreeBSD,
which uses -WError, the only way to build it is to disable all compiler
warnings. This makes it much harder to detect newly introduced bugs. We should
cleanup all the warnings.

This adds sys/modules/imx with a SUBDIR makefile to make the whole
collection of modules that are specific to these SoCs. Initially, that
"whole collection" consists of the if_ffec and imx_i2c drivers.
The if_ffec driver is referenced in its existing home in ../ffec rather
than moving it into the imx directory, because it's used by powerpc too,
but it is no longer built for all armv6/7 systems.
The imx_i2c driver is newly added as a module.
8502 illumos#7955 broke delegated datasets when libshare is not present
illumos/illumos-gate@1c18e8fbd81c18e8fbd8https://www.illumos.org/issues/8502
The code in lib/libzfs/common/libzfs_mount.c already basically handles
the case when libshare is not installed. We just need to not fail in
zfs_init_libshare_impl. I tested this in lx and things work as
expected. I also tested there trying to set sharenfs and sharesmb on
the delegated dataset. Neither is allowed from within a zone. The
spew of msgs from a native zone is not ZFS specific. I see the same
spew simply running the share command.

Some other points I think we need to be consistent on:
- Spacing around string concatenation (always)
- Test against 'nil' explicitly rather than relying on 'not' for things that
reasonably won't be returning a boolean. e.g. loader.getenv
Eventually this will all get formalized somewhere.
Once we've successfully loaded a kernel, we add its directory to
module_path. If we switch kernels with the kernel selector, we again prepend
the kernel directory to the current module_path and end up with multiple
kernel paths, potentially with mismatched kernel/modules, added to
module_path.
Fix it by caching module_path at load() time and using the cached version
whenever we load a new kernel.
appears that node names no longer include leading zeroes in the @address
qualifiers, so we have to search for the nodes involved in interrupt fixup
using both flavors of name to be compatible with old and new .dtb files.
(You know you're in a bad place when you're applying a workaround to code
that exists only as a workaround for another problem.)
would be safe, but the function also tries to destroy mutexes that never
got created).
I guess this can only happen when imx_ehci_detach() is called on the
error-exit path from imx_ehci_attach(), and that path never got exercised
before today.
In a similar fashion to FILE, provide thin shims for the standard directory
manipulation functions.
