Add a set of entries to the fixmap table to allow usage of known

The address space reserved is the top 128K of the 32-bit address

As shown by the previous patch (6698e3472: "tty: Fix BKL taken under a
spinlock bug introduced in the BKL split") the BKL removal is prone to
some subtle issues, where removing the BKL in one place may in fact make
a previously nested BKL call the new outer call, and then prone to nasty
deadlocks with other spinlocks.
In general, we should never take the BKL while we're holding a spinlock,
so let's just add a "might_sleep()" to it (even though the BKL doesn't
technically sleep - at least not yet), and we'll get nice warnings the
next time this kind of problem happens during BKL removal.

The fasync path takes the BKL (it probably doesn't need to in fact)
while holding the file_list spinlock. You can't do that with the kernel
lock: it causes lock inversions and deadlocks.
Leave the BKL over that bit for the moment.

This is to allow fcoemon util to enable or disable a fcoe interface
according to DCB link state change.
Adds sysfs module param enable and disable for this and also
updates existing other module param description to be consistent
and more accurate since older description had double "fcoe" word
with less meaningful netdev reference to user space.
Adds code to ignore redundant fc_lport_enter_reset handling for a
already disabled fcoe interface by checking LPORT_ST_DISABLED
or LPORT_ST_LOGO states, this also prevents lport state transition
on link flap on a disabled interface.
Above changes required lport state transition to get out of
disabled or logo state on call to fc_fabric_login.

Introduce a new lock to protect the list of fc_fcp_pkt structs in libfc
instead of using the host lock. This reduces the contention of this heavily
used lock, and I see up to a 25% performance gain in CPU bound small I/O
tests when scaling out across multiple quad-core CPUs.
The big win is in removing the host lock from the completion path
completely, as it does not need to be held around the call to scsi_done.

We ran into a scenario where a remote port goes into RESTART state, but
never gets added to scsi transport. The running vmcore showed the following:
a) Port was in RESTART state
b) rdata->event was STOP
c) no work gets scheduled for the remote work to fc_rport_work
After this point, shut/no-shut of the remote port did not cause the port
to get re-discovered. The port would move betwen DELETE and RESTART states,
but the event would always be STOP, no work would get scheduled to
fc_rport_work and the port would not get added to scsi_transport.
The problem is that rdata->event is not set to NONE after a port is
restarted. After this point, no more work gets scheduled for the remote port
since new work is scheduled only if rdata->event is non-NONE. So, the event
and state keep changing, but fc_rport_work does not get scheduled to actually
handle the event.
Here's a transition of states that explains the above observation:
) Port is first in READY State, event is NONE
2) RSCN on shut, port goes to DELETED, event is stop
3) Before fc_rport_work runs, RSCN on no-shut, port goes to RESTART, event is
still STOP
4) fc_rport_work gets scheduled, removes the port from transport, sees state
as RESTART, begins the PLOGI state machine, event remains as STOP (event NOT
changed to NONE, this is the bug)
5) Plogi state machine completes, port state goes to READY, event goes to
READY, but no work is scheduled since event was STOP (non-NONE) before.
Fc_rport_work is not scheduled, port remains in READY state, but is not added
to transport.
Things are broken at this point. Libfc rport is ready, but no transport rport
created.
6) now a shut causes port state to change to DELETE, event to change to STOP,
no work gets scheduled
7) no-shut causes port state to change to RESTART, event remains at STOP,
no work gets scheduled
(6) and (7) now get repeated everytime we do shut/no-shut. No way to get out
of this state. Fcc reset does not help too.
Only way to get out is to load/unload module.
Fix is to set rdata->event to NONE while processing the STOP/LOGO/FAILED
events, inside the discovery and rport locks.

distinguish builtin and missing modules, install a modules.builtin file

or 'M'. If we source that config file, the builtin modules appear in

Despite being unused these should also get a CRC calculated.
Primarily I view this as a consistency thing. But I also think this is
one of the reasons why __crc_* need to be weak (which I think should be
avoided, and hence we should have the goal to eliminate this so that
failure to calculate a proper CRC for a symbol causes the build to fail).

Running "make deb-pkg" requires setting KBUILD_PKG_ROOTCMD or
becoming root oneself or it errors out. Unless already running
as root or KBUILD_PKG_ROOTCMD is already set, use fakeroot as a
good default.
With this patch applied, you can run "make oldconfig deb-pkg" as
an ordinary user to build a binary package for an updated kernel
tree and it should just work.
fakeroot is too zealous by default in treating files as owned by
root. Its wrapped stat() sets st_uid and st_gid to 0 for all
files, which causes Git to go on a wild goose chase if
CONFIG_LOCALVERSION_AUTO is set, checking if any file's content
has changed along with its stat information. Avoid this by
telling fakeroot to use the actual owner and group for
preexisting files, by passing it the -u option.

Let the deb-pkg target acquire (fake) root privileges before
running commands that need them. Without such privileges,
deb-pkg errors out because chown fails.
The new KBUILD_PKG_ROOTCMD variable, if defined, is used as a
command to run other commands with possibly fake elevated
privileges. Since this is not needed for the tar-pkg and rpm-pkg
targets, it is only used by deb-pkg. If it is not defined, the
behavior is as before, and the user will have to rerun make as
root.
In other words, as a shortcut, instead of running 'make oldconfig &&
make && fakeroot -u make deb-pkg', one can use the single command
'make oldconfig deb-pkg KBUILD_PKG_ROOTCMD="fakeroot -u"'.

Use the --owner= and --group= options to make sure the entries in
the built tar file are owned by root. Without this change, a
careless sysadmin using the tar-pkg target can easily end up
installing a kernel that is writable by the unprivileged user
account used to build the kernel.
Test that these options are understood before using them so that
non-GNU versions of tar can still be used if the operator is
appropriately cautious.
