Fix a problem with OBJECT IDENTIFIER encoding: need to check the
second subid to be less than 40, not the first when the first
subid is 0 or 1.
Do not exit with non-zero return code if sysctl.conf or sysctl.conf.local files
are absent.

ext2fs: Translate the EXT4_EXTENTS and EXT4_INDEX to the inode flags.

r260545 cleared the inode flags to fix corruption problems but
we still need to pass some EXT4 flags for the ext4 read-only
mode.  None of these attributes has an equivalent in FreeBSD and
are uninteresting for the system utilities so they should be
innaccessible in ext2_getattrib().

Note: we also use EXT4_HUGE_FILE but we use it directly from the
dinode structure so it is not necessary to translate it,

Increase the block-layer backend maximum number of requests to match
the AHCI command queue depth.  This allows a slew of commands issued
by a Linux guest to be absorbed without error.

Handle a VM-exit due to a NMI properly by vectoring to the host's NMI handler
via a software interrupt.

This is safe to do because the logical processor is already cognizant of the
NMI and further NMIs are blocked until the host's NMI handler executes "iret".
