This marks the start of one of the worst API additions in the history of
this library. And as everybody knows the bar is high. Very high.

that we load the kernel into doesn't work. But changing it to EfiLoaderCode
makes it work. Presumably the firmware creates a mapping with executable
permissions in that case, which is obviously needed for executing kernel
code.

Avoid undefined behaviour by negating the unsigned value, before casting
to int64_t, rather than casting to int64_t then negating.

If no memory was immediately available to decrypt (bounce) a page from swap
an error was returned to the fault handler which would result in processes
dying when a lot of memory pressure was applied to a system.
Note that reading from swap is always done synchronously.

Instead of starting with the first page on the inactive list pick the first
one that fits in the range of a given pmemrange region.
Fix an issue where the page daemon would be hogging a CPU without freeing any
page because the global limits are satisfied.
The algorithm could certainly be revisited, the LRU is not really working and
there is a huge delay before recovering when the first pages need to be swapped and the system is in OOM situation but at least there is no starvation and the
system now recovers.

Currently swap encryption is not done in place and some architectures need to
bounce pages into a DMA-reachable region for I/Os, for that uvm_swap_io() needs
to allocate at most 64K to write a swap cluster to disk. Pre-allocate such
amount of memory to be sure the page daemon can make progress in OOM situation.
Also introduce a sleeping point to wait for the previous asynchronous I/O
holding the pre-allocated pages, there's no point in building clusters if no
progress can be made.
ok beck@, kettenis@

This ensures uvm_swap_io() can succeeds even in OOM situations because two
uvm_pagermapin() allocations, requiring a segment each, are needed to bounce
or encrypt a swap cluster.

is later on interpreted as a com_softc pointer. This is not a problem in
practice as a com_softc structure is the first member of the
com_acpi_softc structure.
Using the actual types consistently yields a better symmetry in my
opinion between registering the interrupt and the corresponding
interrupt handler.

Keep the depth which was needed.
This went an error too far, and broke openssl-ruby's callback
and error code sensitivity in it's tests.
With this removed, both my newly committed regress to verify
the same error codes and depths in the callback, and
openssl-ruby's tests pass again.

It was incompatible with OpenSSL 3.0. Remove the regression test
to check that LibreSSL crypto works with Botan tests. This is
better than to keep an outdated Botan in ports.

While this is not a leak currently, it definitely looks like one.

This really pointed out that the place syncookies were hooked in was almost,
but not completely right. The way it was the special case for tcp fast port
reuse in pf_test_state wasn't hit, because the first packet
hitting that was the ACK from the peer finishing the 3WHS, and the
reconstructed SYN came after. We're now doing pf_find_state (and *only* that)
first, then syncookies, then going on so that the old state is thrown away
properly and we get a new one with the sequence number modulator set up
correctly
Bonus: -11 lines of code
tracked down (that took a while) + fixed under contract with Hush

Previously we looked at cpuid 0x80000005 for L1/TLB details
which Intel documents as reserved.
And cpuid 0x80000006 for L2 details.
Intel also encode cache details in cpuid 4.
AMD have mostly the same encoding with cpuid 0x8000001d
0x80000005/0x80000006 is used as a fallback.
Prompted by Intel Tiger Lake and Alder Lake machines
returning an associativity value of 7 from cpuid 0x80000006.
The previous code would print "disabled L2 cache", 7 is
documented by Intel as "See CPUID leaf 04H, sub-leaf 2".
