cacheable window on physical memory (KSEG0). On the Sibyte processor
going through the uncacheable window (KSEG1) bypasses both L1 and L2
caches so we may end up with stale contents in the L2 cache.
This also makes it consistent with the rest of the function that
uses cacheable mappings to copy pages.

fixed-state media with parameters set via hints
and configure MAC accordingly to these parameters.
All the underlying PHY magic is done by boot manager
on startup. At the moment there is no proper way
to make active and control all PHYs simultaneously
from one MII bus and there is no way to associate
incoming/outgoing packet with specific PHY.
original codes (I had changed one by accident)
Also do the pic_ack/pic_delayed_ack after the interrupt
so we clear it. The clock with these changes starts working.
Its off doing a short/long short/long warning but it
now runs.
My NFS mount now works but has the same problem with
sbin/init (errno 8 ENOEXEC) so it panics with no init.
Either this is a problem with my buildworld.. OR its a
yet undiscovered RMI issue.
- Move dpcpu initialization to mips_proc0_init. It's
more appropriate place for it. Besides dpcpu_init
requires pmap module to be initialized and calling it
int pmap.c hangs the system
the mi_startup (or to the last of it).. and
hit a panic after :
uart0: <16550 or compatible> on iodi0
Trap cause = 2 (TLB miss....)
I did have to take the pci bus OUT of the
build to get this far, hit a cache error with
the PCI code in. Interesting thing is the machine
reboots too ;-)
addresses and could modify areas of memory that share the same cache
line at the beginning and at the ending of the buffer. In order to
prevent a data loss we save these chunks in temporary buffer before
invalidation and restore them afer it.
Idea suggested by: cognet
while in kernel mode, and later changing signal mask to block the
signal, was fixed for sigprocmask(2) and ptread_exit(3). The same race
exists for sigreturn(2), setcontext(2) and swapcontext(2) syscalls.
Use kern_sigprocmask() instead of direct manipulation of td_sigmask to
reschedule newly blocked signals, closing the race.
