With an i386 kernel the igb driver can cause a
page fault panic on initialization due to a large
number of bounce pages being allocated. This is due
to the dma tag requiring page alignment on mbuf mapping.
This was removed some time back from the ixgbe driver
and is not needed here either.

Create verifier used by FreeBSD NFS client is suboptimal because the
first part of a verifier is set to the first IP address from
V_in_ifaddrhead list. This address is typically the loopback address
making the first part of the verifier practically non-unique. The second
part of the verifier is initialized to zero making its initial value
non-unique too.
This commit changes the strategy for create verifier initialization:
just initialize it to a random value. Also move verifier handling into
its own function and use a mutex to protect the variable.
This change is a candidate for porting to sys/nfsclient.

Controller does not update Tx descriptors(send BDs) after sending
frames so remove unnecessary BUS_DMASYNC_PREREAD and
BUS_DMASYNC_POSTREAD of bus_dmamap_sync(9).
When rename("a", "b/.") is performed, target namei() call returns
dvp == vp. Rename syscall does not check for the case, and at least
ufs_rename() cannot deal with it. POSIX explicitely requires that both
rename(2) and rmdir(2) return EINVAL when any of the pathes end in "/.".
Detect the slashdot lookup for RENAME or REMOVE in lookup(), and return
EINVAL.
In r198506, kern_sigsuspend() started doing cursig/postsig loop to make
sure that a signal was delivered to the thread before returning from
syscall. Signal delivery puts new return frame on the user stack, and
modifies trap frame to enter signal handler. As a consequence, syscall
return code sets EINTR as error return for signal frame, instead of the
syscall return.
Also, for ia64, due to different registers layout for those two kind of
frames, usermode sigsegfaulted when returned from signal handler.
Use newly-introduced cpu_set_syscall_retval(9) to set syscall result,
and return EJUSTRETURN from kern_sigsuspend() to prevent syscall return
code from modifying this frame [1].
Another issue is that pending SIGCONT might be cancelled by SIGSTOP,
causing postsig() not to deliver any catched signal [2]. Modify
postsig() to return 1 if signal was posted, and 0 otherwise, and use
this in the kern_sigsuspend loop.
Remove a bunch of code used to detect SMP on ((i386 && !pc98) || amd64) and
offer to install an SMP kernel. The way this worked was: on supported
platforms, code to read ACPI tables and BIOS MP tables was compiled into
sysinstall, and if an SMP kernel config was present in the source tree when
sysinstall was built, code that called it was also compiled. Since we
haven't had SMP kernel configs in years, the latter was never compiled and
the former never ran.
This only removes dead and unreachable code; it does *not* remove the NCpus
variable, nor the code that sets it to 1, nor the code that asks the user to
select a kernel from a list.
