1733a6c1df Set bp->b_resid for failed transfers in dscheck(). This is the
best place to set it, and the wd and wfd strategy routines don't
set it (for failed transfers) because they expect dscheck() to
initialize everything necessary.  dscheck() has always set B_ERROR,
but this is not quite sufficient, because b_resid is used by physio()
to decide how much of a B_ERROR'ed i/o was done.

aa6db4230d Used daddr_t's, not ints, to store disk block numbers. Updated printf
formats and args to match.  Fixed old printf format errors (all related;
most were hidden by calling printf indirectly).

This change somehow avoids compiler bugs for 64-bit longs on i386's,
although it increases the number of 64-bit calculations.

e539380ea8 Set p->p_switchtime to switchtime instead of to the current time in
fork_trampoline() if switchtime is valid.  This fixes not accounting
for the time between the previous context switch and and the current
time (when the forked child starts up here) in most cases - the time
is now counted in the child's runtime.  I think it actually fixes
all cases, and switchtime is always valid here, since there must have
been a context switch just before the forked child starts up.  Some
code should be removed if this is correct.  The check that switchtime
is valid sometimes gives a false negative because the check isn't
correct until the after the first context switch after the system
has been up for >= 1 second.

ccbbd9271b Fixed two spl nesting bugs. They caused (at least) the entire pageout
daemon to run at splvm() forever after swap_pager_putpages() is called
from vm_pageout_scan().

358cb8ddc1 I have a PD drive (Matsushita PD/CD Drive LF-1600).
The machine can not recognize this PD drive
as neither PD drive nor CD-ROM Drive.
So I can not use CD-ROMs and PDs from FreeBSD.

Cosmetic cleanup of the code to de-obfuscate it and make it easier
to follow.  There should be no functional changes in this commit.

df9efa9a8b On the alpha, ports may be allocated above 64k.
Change the port address argument to pci_map_port to pci_port_t* which is
defined as u_int on the alpha, u_short on i386.  This is a stopgap with a
hopefully limited lifetime.
