This patch causes the "calltodo" timer list to be decremented by the amount
of time that the laptop was suspending. Thus, select() calls that might have
suspended rather than firing at 1hr + "time suspended" since the timer was
posted.
Adding:
options APM_FIXUP_CALLTODO
to the kernel config enables the patch.
[
This patch was slightly modified to use a consistant indent style and
I removed some unused local variables. After this has been tested a
few weeks we'll make the options the default, so for now I'm now
documenting it in LINT. Mike can later if he wants.
