7e08ec5c00 Retain offset compatibility with pre-12.0 dumps
As a follow-up to r324965, which adds support for compressed kernel dumps,
readjust dump header members slightly to mostly preserve ABI with earlier
(11.x and older) dumps.

906c9ca619 Check for a 'pci' prefix rather than a full match in get_addr_props
Summary:
Newer OPAL device trees, such as those on POWER9 systems, use 'pciex' for
device_type, not 'pci'.  Rather than enumerating all possible variants, just
check for a 'pci' prefix.

1df055488a lib32: Fix lib/libpmc/pmu-events files ending up in source directory.
This could happen with either WITHOUT_AUTO_OBJ=yes or MAKELEVEL>0 for
the initial 'make buildworld' command.

This now ensures that build-tools targets have 'make obj' ran if needed.

This is especially problematic for pmu-events since it is not directly
connected in the build.  Normally the 'make includes' call right before
this implicitly creates the objdir with a 'make obj' already but
misses pmu-events because it is disconnected from lib/libpmc.  Fixing that
would make this new 'make obj' pointless but it is being added to avoid
this problem in the future should another tool be connected like this.

3203027a49 extres/regulator: Switch boot_on/always_on sysctl to uint8
These are represented as booleans on the kernel-side, but were being exposed
as int. This was causing some funky things to happen when read later with

such as non-*at ones like open, but arm64 and other new platforms do
not.

Wrap these in #ifdef LINUX_LEGACY_SYSCALLS, #defined in the MD linux.h
files.  We may need finer grained control in the future but this is
sufficient for now.

This was the wrong solution to the problem; regulator_shutdown invokes
regnode_stop. regulator_stop is not a refcounting method, but it invokes
regnode_enable, which is.

mmel@ has a proposed patch/solution to instead provide regnode_fixed_stop
behavior that properly takes shared GPIO pins into account.

f343969480 When retransmitting TCP SYN-ACK segments with the TCP timestamp option
enabled use an updated timestamp instead of reusing the one used in
the initial TCP SYN-ACK segment.

This patch ensures that an updated timestamp is used when sending the
SYN-ACK from the syncache code. It was already done if the
SYN-ACK was retransmitted from the generic code.

This makes the behaviour consistent and also conformant with
the TCP specification.

901e67d37d allwinner: ccung: Fully subclass the clock drivers
Each clock drivers if now fully subclassed, this have the advantage that
we can control the probe order.
Some clocks can have parents from other drivers, for example clocks in the
sun8i_r driver uses clocks from the main clock driver.
This worked before because the sun8i_r node is after the main ccu node in the
dtb and driver are probed in DTB order. This cannot work with the Display
Engine clocks as it is the first node in the DTB.

07d7582723 extres/regulator: Properly refcount gpio regulators
regnode::enable_cnt is generally used to refcount regulator nodes. For
GPIOs, the refcount was done on the gpio_entry since more than one regulator
can share a GPIO.

GPIO regulators were not taking part in the node refcount, since they had
their own mechanism. This caused some fallout after manu started disabling
everybody's unused regulators in r331989.

Refcount it.

67a7e74847 Handle the race between fork/vm_object_split() and faults.
If fault started before vmspace_fork() locked the map, and then during
fork, vm_map_copy_entry()->vm_object_split() is executed, it is
possible that the fault instantiate the page into the original object
when the page was already copied into the new object (see
vm_map_split() for the orig/new objects terminology). This can happen
if split found a busy page (e.g. from the fault) and slept dropping
the objects lock, which allows the swap pager to instantiate
read-behind pages for the fault.  Then the restart of the scan can see
a page in the scanned range, where it was already copied to the upper
object.

Fix it by instantiating the read-ahead pages before
swap_pager_getpages() method drops the lock to allocate pbuf.  The
object scan would see the whole range prefilled with the busy pages
and not proceed the range.

Note that vm_fault rechecks the map generation count after the object
unlock, so that it restarts the handling if raced with split, and
re-lookups the right page from the upper object.
