was broken by one of the early vmlocking merges, which removed the kthread
that did the initial detection / attachment and instead called the code
directly from the PCMCIA controller attach method.
Submitted in PR port-hpcarm/37227 by Peter Postma; I've tweaked it ever-so-
slightly.
have gotten fatter with age and even the stock kernels were bigger than the
code could handle.
Thanks to Jason Mitchell for sending me a Jornada 720 so I could actually
test this.
MI code always calls pmap_deactivate/pmap_activate on context switch.
Instead, just record the last active lwp (or NULL if it exited) and
defer switching VM context to pmap_activate(). This saves an additional
function call overhead in cpu_switchto().
While here, g/c unused cpuswitch.S local .Lblock_userspace_access.

- Make bpf's read timeout work more correctly with select/poll.
- A fix for catchpacket() which delays calling bpf_wakeup() until
the state has been updated.
in which "/wherever/src.2/../tools" was incorrectly changed to
"/wherever/src./tools" instead of the desired "/wherever/tools".
It's not clear to me that this script has any business trying to do this
sort of rewriting (and there's no guarantee that "/wherever/foo/.." and
"/wherever" both refer to the same place), but at least the new code
tries to be more careful than the old code.
Also while here fix the delay loop used before timers are enabled to
cause a delay, by using a volatile int to do a countdown. gcc has become
intelligent enough to optimize an empty loop away.
For delay on PXA270 we should use one of the other counters, and a 1Mhz
clock, so that we don't have to computer the counter increment.
XXX: also looks like there's a bug if the counter wraps, as delay doesn't
look like it allows for that.
condition), it leaves the control message with file descriptors. Calling
unp_dispose() will interpret the message as containing file pointers
and crash the system.
This change removes unp_dispose() from this failure path and avoids
using goto to jump into switch statements...
The previous workaround to ignore such messages in unp_scan() is removed.
the SDA/SCL pin direction, by treating the direction as just that; a hint.
Instead, configure the SDA/SCL pins as outputs only when they are to
be driven low (zero). Otherwise configure them as inputs and allow the
pull-up resistors to do their jobs.
Check the SDA direction hint only if DIAGNOSTIC.
Fixes a problem reported by Donald T Hayford on port-arm@ whereby the
kernel failed to read/write the RTC's registers.
