2ee4dc6565 Add INHERIT_XXX defines for minherit() system call. 
Remove MAP_INHERIT - it is no longer supported.

c45da89917 Remove MAP_NOEXTEND. It came from 4.4-lite and not only was never 
implemented, but mmap()'s default behavior is *already* to not extend
files.  Only write() or ftruncate() can extend a file.

d625c99d74 Explain what we're doing in pcic_pci_shutdown a little better. Try to 
explain the subtle side effects that are going to happen and why we go
ahead and ack the interrupt source.  This stuff is tricky to get
right.

Also, emperical tests have shown that doing a shutdown in attach to be
ineffectual, so remove it from there.  Analysis of the code paths
shows that nearly identical writes to these registers happen in later
parts of the code.  The hanging problem on thinkpads when we change
the interrupt routing type is something else.

662460d3d5 Move code to shutdown the pcic_pci_shutdown. Call it on system 
shutdown and also before we get going with the device initialization.
This may fix the hangs some people are seeing on warmboot.  It appears
that some machines will reset the cardbus bridge on boot, while others
don't.  So we turn off the card, and ack the interrupts (which likely
is a nop in the shutdown case since we're still fielding interrupts).
This should turn off the interrupts.

Since I don't have hardware that hangs on reboot, I'm committing this
without testing that aspect of the patch (it causes no harm on my
Dell).

9bec31a4c0 Two fixes. First, put into place a more generic chipset specific 
initialization structure.  Warn the user for those chipsets that
aren't yet customized that they might not work.  Second, try to power
off the slot on attach and ack the interrupts.  I don't know, but this
might solve the hangs that people will see on Thinkpads if they set
hw.pcic.init_routing=1.

fa081a357e In order for the MA301 to pass interrupts from the PCCard, you must 
go into the PLX 9052's interrupt control register and turn on the magic
interrupt enable bit.

Partial thanks are due to OpenBSD for pointing out that the chip is a
PLX 9052 and pointing me to the datasheet PDF.

1432aa0c5e Add a new kernel option RESTARTABLE_PANICS. If this option is present, 
then one can restart from a panic by resetting the panicstr variable to
NULL.  This commit conditionalizes the previously committed functionality
on this variable.  It also removes the __dead2 attribute from the panic()
function so that when one continues from a panic() the behavior will
be predictable.
