object that requires Giant in vm_object_deallocate(). This is somewhat
hairy in that if we can't obtain Giant directly, we have to drop the
object lock, then lock Giant, then relock the object lock and verify that
we still need Giant. If we don't (because the object changed to OBJT_DEAD
for example), then we drop Giant before continuing.

a calcru() wrapper that passes a local rusage_ext on the stack that is
a snapshot to do the calculations on. Now we can pass p->p_crux to
calcru1() in calccru() again which fixes the issues with runtime going
backwards messages when dead processes are harvested by init.

processing the interrupt events. If we clear them afterwards we
can completely miss some events as the NIC can change the source
flags while we're in the handler. In order to not get another
interrupt while we're in ifp->if_input() with the driver lock
dropped we now turn off NIC interrupts while in the interrupt
handler. Previously this was meant to be achieved by clearing the
interrupt source flags after processing the interrupt events but
didn't really work as clearing these flags doesn't actually
acknowledge and re-enable the events.
This fixes the device timeouts seen with the VMware LANCE.
- Relax the watchdog timer somewhat; don't enable it until the last
packet is enqueued and if there is a TX interrupt but there are
still outstanding ones reload the timer.

Please note that the files
sys/dev/myri10ge/{mcp_gen_header.h,myri10ge_mcp.h} are internally
shared between all our drivers (solaris, macosx, windows, linux, etc).
I'd like to keep these files unchanged, so I can just import newer
versions of them when the firmware API/ABI changes. This means I'm
stuck with some of the crazy-long #define names, and possibly
non-style(9) characteristics of these files.
Many thanks to mlaier for doing firmware(9) just as I
needed it, and to scottl for his helpful review.

when option DEBUG_LOCKS is used. Trap frames are determined by checking
whether the caller was one of the tl0_*() or tl1_*() asm functions via
a newly added pair of dummy symbols in exception.S which mark the begin
and end of these functions. The tl_trap_* pair marks those in the special
.trap section and the tl_text_* in the regular .text section. Because
of their performance penalty db_search_symbol()/db_symbol_values() and
linker_ddb_search_symbol()/linker_ddb_symbol_values() aren't used here
for determining the caller, with db_search_symbol()/db_symbol_values()
additionally not being reentrant.
- For consistency, change db_backtrace() to also use the new markers for
determining the tl0_*() and tl1_*() asm functions instead of bcmp()'ing
the symbol name.
- Use FBSDID in db_trace.c.

Without CODA_COMPAT_5, it would be equivalent to the plain coda
module. Therefore just add -DCODA_COMPAT_5 to CFLAGS instead of
fiddling with opt_coda.h. This is particularly important when
the module is built along with the kernel and CODA_COMPAT_5 isn't
in the kernel conf file (and so not in opt_coda.h either).

Having jumbo clusters with the native PAGE_SIZE is more useful than
