swcr_newsession can change the pointer for swcr_sessions which races with
swcr_process which is looking up entries in this array.
Add a rwlock that protects changes to the array pointer so that
swcr_newsession and swcr_process no longer race.

the memory ranges that they decode for downstream devices rather than
creating ResourceProducer range resource entries. The result is that
we allocate the full range to the PCI root bridge device causing
allocations in child devices to all fail.
As a workaround, ignore any standard memory resources on a PCI root
bridge device. It is normal for a PCI root bridge to allocate an I/O
resource for the I/O ports used for PCI config access, but I have not
seen any PCI root bridges that legitimately allocate a memory resource.

The ext4 inode flags do not have equivalents for chflags (1)
and hold information that is private to the implementation.
The i_flag field in the inode is a better place to hold the Ext4
inode flags as it saves us from masking flags while setting or
getting attributes. It should also make things cleaner if we
implement write support for Ext4.

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.
