it's freed by devfs_ruleset_reap and pointer becomes bogus.

some time now so collapse calls accordingly.
o Given that gem_load_txmbuf() is allowed to fail resulting in a packet
drop also for quite some time now implement the functionality of
gem_txcksum() by means of m_pullup(9), which de-obfuscates the code
and allows to always retrieve the correct length of the IP header.
o Add missing BUS_DMASYNC_PREREAD when syncing the control DMA maps in
gem_rint() and gem_start_locked().
o Correct some bus_barrier(9) calls to do a read/write barrier as we
do a read after a write. Add some missing ones in gem_mii_readreg()
and gem_mii_writereg().
o According to the Apple GMAC driver, the GEM ASIC specification and
the OpenSolaris eri(7D) the TX FIFO threshold has to be set to 0x4ff
for the Gigabit variants and 0x100 for the ERI in order do avoid TX
underruns.
o In gem_init_locked():
- be conservative and enable the RX and TX MACs,
- don't clear GEM_LINK otherwise we don't ever mark the link as up
again if gem_init_locked() is called from gem_watchdog(),
- remove superfluous setting of sc_ifflags.
o Don't bother to check whether the interface is running or whether its
queue is empty before calling gem_start_locked() in gem_tint(), the
former will check these anyway.
o Call gem_start_locked() in gem_watchdog() in order to try to get
some more packets going.
o In gem_mii_writereg() after reseting the PCS restore its configuration.

on the amd64 architecture. The amd64 architecture requires kernel code and
global variables to reside in the highest 2GB of the 64-bit virtual address
space. Thus, the memory allocated during bootstrap, before the call to
kmem_init(), starts at KERNBASE, which is not necessarily the same as
VM_MIN_KERNEL_ADDRESS on amd64.

number of kernel map entries. Intead, use VM_MIN_KERNEL_ADDRESS, which marks
the start of the kernel map on all architectures.

KERNBASE and VM_MIN_KERNEL_ADDRESS are no longer the same, the physical
memory allocated during bootstrap will be offset from the low-end of the
kernel's page table.

and use later timestamps (timestamps too close to the Epoch fail
predictably on systems that lack timegm(), whose mktime() doesn't
support dates before the Epoch and which are running in timezones
with negative offsets from GMT). The goal here is to test the ISO
extraction, not the local platform's time support.

Both bsdtar and bsdcpio will try to copy file contents after an ARCHIVE_WARN,
which will fail loudly.

In particular, this should fix the COPYTREE_* macros used in the
ports infrastructure which use -l to preserve space but often get
used for cross-device copies.

However, KERNBASE is sometimes used as the start of the kernel virtual

instead. Since KERNBASE and VM_MIN_KERNEL_ADDRESS are still the same
address, there should be no visible effect from this change (yet).
That said, kris@ has tested crash dumps under the full patch that
increases the kernel virtual address space on amd64 to 6GB.

noticed that a "whereis -qs qemu" matched the distfiles subdir of qemu
rather than /usr/ports/emulators/qemu.
It now ignores all dot entries in /usr/ports, plus all entries
starting with a capital letter (maintenance stuff like Templates, but
also includes subdir CVS), plus /usr/ports/distfiles which is simply a
magic name in that respect.

When GCC is invoked with -std=c99, the following errors are displayed when
including <spawn.h>:
/usr/include/spawn.h:69: error: static or type qualifiers in abstract declarator

/usr/include/spawn.h:72: error: static or type qualifiers in abstract declarator

We'd better remove the __restrict keywords here. The same is also done
in <regex.h>.
