a500a7ce91 Bus space handles need to be the VA of the requested resource, not the 
rounded page VA. Correct so the DBGU device can be mapped for FDT
console since it isn't on a page boundary.

30b94db8c0 Support level triggered interrupts with VT-x virtual interrupt delivery. 
The VMCS field EOI_bitmap[] is an array of 256 bits - one for each vector.
If a bit is set to '1' in the EOI_bitmap[] then the processor will trigger
an EOI-induced VM-exit when it is doing EOI virtualization.

The EOI-induced VM-exit results in the EOI being forwarded to the vioapic
so that level triggered interrupts can be properly handled.

9ef6342f9e Check for a full virtqueue in the multiqueue transmit path 
With most hosts, we'll negotiate indirect descriptors, so all we
need is one available descriptor to transmit a frame.

dd6f83a00f Avoid queue unlock followed by relock when the enable interrupt race is lost 
This already happens infrequently, and the hold time is still bounded since
we defer to a taskqueue after a few tries.

b65c25f54a Fix 32-bit signal handling on ppc64. This was broken when the PSL_USERSTATIC 
macro was changed.  Since copying 64-bit srr1 into 32-bit srr1 drops the upper
32 bits, any bits set in the context were dropped, meaning the context check
fails.  Since 32-bit set_context can't change those bits anyway, copy the ones
from the current context (td->td_frame) before calling set_context().

d0754f0829 Mostly revert r260267 and hopefully really fix the original problem. 
The latest draft of SBC-3 tells: "A MAXIMUM UNMAP LBA COUNT field set to
a non-zero value indicates the maximum number of LBAs that may be unmapped
by an UNMAP command."  To me it does not sound like that limit is set per
single descriptor, but rather per all command.  And I have at least one
device that behaves exactly that way.  This patch fixes the problem there.

to provide its own eputc, and possibly do other things as well...
