only 1.5Gbps, when 3Gb/s devices connected.
Add dummy driver for PATA part of these controllers, preventing generic
driver attach them. It causes system freeze when SATA controller used after
PATA was touched.

You need to follow the mips wiki for building

the intention of having two ttys pointing to the same cfe console device was.
Also we were not initializing the output[] array passed in as input to
tty_makedev() so one name of the ttys was garbage.
Fix the code that calls cfe_write() to deal with the case where only a partial
buffer is written out.
cfe_cngetc() needs to return if there is no character available as input.
If we don't do this then the cfe_timeout() function will spin forever
because cfe_cngetc() will only ever return if there is valid input.

This is a workaround for the fact that the CFE is compiled as a 64-bit
application and therefore sets the SR_KX bit every time we call into
it (for e.g. console).
A TLB miss for any address above 0xc0000000 with the SR_KX bit set will
end up at the XTLB exception vector. We workaround this by copying the
standard TLB handler at the XTLB exception vector.

through fork_trampoline.
This was caused because we were clearing the SR_INT_IE and setting
SR_EXL bits of the status register at the same time. This meant
that if an interrupt happened while this MTC0 was making its way
through the pipeline the exception processing would see the
status register with SR_EXL bit set. This in turn would mean that
the COP_0_EXC_PC would not be updated so the return from exception
would be to an incorrect address.
It is easy to verify this fix by a program that forks in a loop
and the child just exits:
while (1) {
pid_t pid = vfork();
if (pid == 0)
_exit(0);
if (pid != -1)
waitpid(pid, NULL, 0);
}
Also remove two instances where we set SR_EXL bit gratuitously in exception.S.

Continuous catopen() calls cause 4 failig stat(2) each, which means a lot
of overhead. It is also a good idea to keep the opened catalogs in the memory
to speed up further catopen() calls to the same catalog since these catalogs
are not big at all. In this case, we count references and only free() the
allocated space when the reference count reaches 0. The reads and writes to
the cache are syncronized with an rwlock when these functions are called from
a threaded program.

obio. Take advantage of the fact that obio only really supports uart
at the moment to use the uart bus tag always for IOPORT allocations.
# this needs to be redone to conform to FreeBSD standards and allow for
# additional drivers for SoC hardware to attach
in the pcb at the td_lock offset, rather than in the struct thread at
the td_lock offset. And we were storing a pointer to the old thread
rather than to the mutex. Why this didn't always kill us, I'll never
know.
Fix an obsolete comment and update the prototype in the comments.
Also note what variables are in what registers since this function is
a little complex...

where the type is 32-bit. ZFS can handle 64-bit timestamp internally
but zfs_setattr() would check if the time value can fit, we change the
checking macros to match 64-bit timestamp if the platform supports it.
This change has some downsides like, while you can import zfs on 32-bit
platforms, the timestamp would overflow if they are out of the range.
This fixes the Y2.038K issue on platforms using 64-bit timestamps.
