The sysreg.h file has been checked by hand, however it may contain errors
with the comments on when a register was first introduced. The ARMv7 cpu
functions have been checked by compiling both the previous and this version
and comparing the md5 of the object files.

do not assume EVERY connection coming to socket
with TCP_SIGNATURE set to be md5 signed regardless
of SADB key existance for particular address. This
fixes the case for routing software having _some_

As of git submit e179f6914152eca9, the Linux kernel does a simple
probe of the PIC by writing a pattern to the IMR and then reading it
back, prior to the init sequence of ICW words.
The bhyve PIC emulation wasn't allowing the IMR to be read until
the ICW sequence was complete. This limitation isn't required so
relax the test.
With this change, Linux kernels 3.15-rc2 and later won't hang
on boot when calibrating the local APIC.

The VFS_UNMOUNT() methods for UFS and tmpfs try to establish
suspension on unmount, while covered vnode is locked by VFS, which
prevents namei() from stepping over the mount point. The thread doing
namei() sleeps on the covered vnode lock, owning the write ref.

node's interrupts=<...> property creating resource list entries with a
single common implementation. This change makes ofw_bus_intr_to_rl() the
one true copy of that code and removes the copies of it from other places.
This also adds handling of the interrupts-extended property, which allows
specifying multiple interrupts for a node where each interrupt can have a
separate interrupt-parent. The bindings for this state that the property
cells contain an xref phandle to the interrupt parent followed by whatever
interrupt info that parent normally expects. This leads to having a
variable number of icells per interrupt in the property. For example you
could have <&intc1 1 &intc2 26 9 0 &intc3 9 4>.

When the FreeBSD kernel is loaded from Xen the symtab and strtab are
not loaded the same way as the native boot loader. This patch adds
three new global variables to ddb that can be used to specify the
exact position and size of those tables, so they can be directly used
as parameters to db_add_symbol_table. A new helper is introduced, so callers
that used to set ksym_start and ksym_end can use this helper to set the new
variables.
It also adds support for loading them from the Xen PVH port, that was
previously missing those tables.

can be used to specify the position and size of the symtab and
strtab.
- Use those new variables in db_init in order to call db_add_symbol_table.
- Move the logic in db_init to db_fetch_symtab in order to set ksymtab,
kstrtab, ksymtab_size from ksym_start and ksym_end.
