This is done explicitly because a vcpu thread can be in a critical section
for the entire time slice alloted to it. This in turn can delay the handling
of the 'td_owepreempt'.

The function clearning credentials on failure asserts the process is a
zombie, which is not true when fork fails.
Changing creds to NULL is unnecessary, but is still being done for
consistency with other code.

o Restore historical behaviour of appending '*' if interface is down,
and we have enough space to print it (usually we don't). [1]
o Do not truncate interface names when printing in encoded format.
o Report interface flags into encoded format.

Prior to this change both functions returned 0 for success, -1 for failure
and +1 to indicate that an exception was injected into the guest.
The numerical value of ERESTART also happens to be -1 so when these functions
returned -1 it had to be translated to a positive errno value to prevent the
VM_RUN ioctl from being inadvertently restarted. This made it easy to introduce
bugs when writing emulation code.
Fix this by adding an 'int *guest_fault' parameter and setting it to '1' if
an exception was delivered to the guest. The return value is 0 or EFAULT so
no additional translation is needed.

The requirement is for a GCC-compatible compiler and not necessarily
GCC itself. However, we currently expect any compiler used for building
the whole of FreeBSD to be GCC-compatible and many things will break if
not; there's no longer a need to have an explicit test for this in rtld.

1. While disabling interrupt the FW disables interrupts for only 16 vectors.
In case of Invader which supports 96 MSI-x vectors, some spurious interrupts
may come on other vectors even after interrupt disable. So, driver uses a flag
and ignores the spurious interrupts.
2. Reply queue depth is made double the number of commands supported by FW.
3. Misplaced interrupt enable code is now moved down in the OCR path.
4. Updated error handling code in OCR path.
5. Removed un-necessary print.

There will be a small window where IO will come from OS with old RAID map.
This patch will update adapter state to MEGASAS_HBA_OPERATIONAL,
only after driver has new RAID map to avoid any IOs getting build using old RAID map.

each of the existing kernel configs. This gives a place to put config
that applies to the entire arch.
Add the ARM_NEW_PMAP option to std.armv6. This is working well in early
testing and it's time for wide exposure, but it's still nice to be able
to fall back to the old implementation for testing when a problem comes
along. Eventually the option and the old implementation will go away.
The opportunity now exists to move a whole lot of boilerplate from all the
arm kernel config files into std.arm*, but that's a commit for another day.
