hppa reverse-stack gives us a valuable test case, but most developers don't
have a 2nd one to proceed further with this.

started and before init(8) has opened the console, the kernel could
crash as the console device has not been initialized. Open
/dev/console in the kernel before starting init(8) and keep it open.
This way sendsyslog(2) can be called early in the system.

this makes it more obvious that the bpf code should only read
packets, never modify them.

exact PC addr in the (per-process ASLR) sigtramp, verifies the cookie,
and clears it to prevent sigcontext reuse.

It is supposed to control whether an amap should allocate memory
to store anon pointers lazily or upfront. Needed for upcoming amap
changes.

Only fail hard when running out of swap space also, as suggested by

While there, let amap_add() return a success status and handle
amap_add() errors in uvm_fault() similar to other out of RAM situations.
These bits are needed for further amap reorganization diffs.

we attach the device itself. The _DEP methode, introduced in ACPI 5.0,
is a hint that the device in question depends on OpRegion support from
the devices listed by _DEP, so we have to order them the proper way.
To prevent us from attaching those devices again when we encounter them
later walking down the device tree, keep track of our attempts to
attach a device driver to them using aflag in the aml_node structure.

This stores errno, the cancelation flags, and related bits for each thread
and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable!
Make libpthread dlopen'able by moving the cancelation wrappers into libc
and doing locking and fork/errno handling via callbacks that libpthread
registers when it first initializes. 'errno' *must* be declared via
<errno.h> now!
Clean up libpthread's symbol exports like libc.
On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec.

registers. For now this only implements peeking at pins. It will print
a message if AML attempt to poke at a pin. And it will panic if the
assumptions made in the code are violated.

the tx dma maps, apparently to allow heavily fragmented packets to be sent.
The tx ring accounting in bnx_start assumed that the longest fragment chain
we'd see was BNX_MAX_SEGMENTS, so sending a heavily fragmented packet when the
ring was already full could cause it to overflow.
In the 10 years since r1.10, we've started defragmenting packets if they
won't fit in the dma map, so we can limit the maps to BNX_MAX_SEGMENTS again.
While we're here, ensure there's always at least one slot on the tx ring free,
for consistency between drivers.
