The internal architecture name of golang is "arm" or "arm64", which has
different naming conventions from netbsd's machine[] or machine_arch[]
("earmv7", "aarch64", etc.) and cannot be used as is.
Instead, use define LINUX_GO_RT0_SIGNATURE_ARCH{32,64}.

Tidy up the vnode locking around execve() on ELF images to acquire and
release the locks fewer times. Proposed on tech-kern a very long time go.

Rename the MODULE_*_HOOK() macros to MODULE_HOOK_*() as briefly
discussed on irc.

NFCI intended.

Ride the earlier kernel bump - it;s getting crowded.

Merge the [pgoyette-compat] branch

- fix constants and explain limit
- use machine32 instead of hard-coded x86 stuff

Fix compile error.

Enable executing linux go binaries by using a special probe function for them.

Use ELFOSABI_LINUX instead of a magic number.

Force *stackp to (uintptr_t) before possibly moving to a smaller pointer size.

Zero-fill the ELF auxiliary vectors. Otherwise, on 64bit systems, the
padding between a_v and a_type contains kernel garbage, therefore
exposed to userland.

A specially-crafted binary could easily control a kernel array index.
Add some checks to ensure that nothing will be read outside the allocated
area. Rewrite the code so that we don't need to allocate the whole section.

Fix wrong KASSERTs. Do not compare size vs. entries count.

Increase LINUX32_ELF_AUX_ENTRIES to avoid overrun in linux32/. Also,
add comments and KASSERTs to make sure people don't forget to increase
XX_AUX_ENTRIES's when adding vectors.

always supply an auxiliary vector for linux ELF processes.
static executables (such as newer versions of /sbin/ldconfig)

linux does to provide a value for AT_PHDR in this case.

Change the way that emulations locate files within the emulation root to
avoid having to allocate space in the 'stackgap'
- which is very LWP unfriendly.
The additional code for non-emulation namei() is trivial, the reduction for
the emulations is massive.
The vnode for a processes emulation root is saved in the cwdi structure
during process exec.
If the emulation root the TRYEMULROOT flag are set, namei() will do an initial
search for absolute pathnames in the emulation root, if that fails it will
retry from the normal root.
".." at the emulation root will always go to the real root, even in the middle
of paths and when expanding symlinks.
Absolute symlinks found using absolute paths in the emulation root will be
relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links
inside the emulation root don't need changing).
If the root of the emulation would be returned (for an emulation lookup), then
the real root is returned instead (matching the behaviour of emul_lookup,
but being a cheap comparison here) so that programs that scan "../.."
looking for the root dircetory don't loop forever.
The target for symbolic links is no longer mangled (it used to get the
CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended).
CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding
TRYEMULROOT to the flags to NDINIT().
A lot of the emulation system call stubs could now be deleted.
