Add a helper to asm/pdc.h to translate OS_ID values to strings
and use it in the pdc_stable driver.

We were assigned an OS_ID of 0x0006. Consistently use OS_ID_LINUX
instead of using the magic number. Also update the OS_ID_ defines in
asm/pdc.h to reflect this.

pdc_stable v0.30:
This patch introduces 3 more files to the /sys/firmware/stable tree:
- diagnostic, which contains a cryptic hex string
- osdep1, a 16 bytes os-dependent storage area always available
- osdep2, another os-dependent storage area which existence/size depends
on hversion.
This patch also adds code to setup the "Linux" signature in stable
storage. That is to say that starting with this patch, the kernel will
now sign its OSID (0x0006, thx LaMont) in Stable Storage upon boot,
whether pdc_stable is enabled or not.

This patch removes a limitation of the original code, so that CHASSIS
codes can be sent to all machines. On machines with a LCD panel, this
code displays "INI" during bootup, "RUN" when the system is booted and
running, "FLT" when a panic occurs, etc.
This part of the code can be enabled/disabled through CONFIG_PDC_CHASSIS
This patch also adds minimalistic support for Chassis warnings, through
a proc entry '/proc/chassis', which will reflect the warnings status (PSU
or fans failure when they happen, NVRAM battery level and temperature
thresholds overflows).
This part of the code can be enabled/disabled through CONFIG_PDC_CHASSIS_WARN

Allow lseek(mtdchar_fd, 0, SEEK_END) to succeed, which currently fails
with EINVAL.
lseek(fd, 0, SEEK_END) should result into the same fileposition as
lseek(fd, 0, SEEK_SET) + read(fd, buf, length(fd))
Furthermore, lseek(fd, 0, SEEK_CUR) should return the current file position,
which in case of an encountered EOF should not result in EINVAL

Original post was incorrect as it didn't realize that we already had
a self-referenc due to device_initialize(), and we were really only
missing the put on our own reference. This was hidden by the other bug
which had the midlayer reusing stargets after they were already free,
which was doing too many puts on our rport.
Updating FC transport for:
- Add put in fc_rport_final_delete(), to release the rport.
Prior, we were leaving the rport with a reference, thus the shost
with references, etc. If the driver was unloaded, shosts and rports
remained, along with work threads, etc
- Fix fc_rport_create failure path - too many put's on parent
- Add commenting to easily track ref taking.

In a prior posting to linux-scsi on the fc transport and workq
deadlocks, we noted a second error that did not have a patch:
http://marc.theaimsgroup.com/?l=linux-scsi&m=114467847711383&w=2
- There's a deadlock where scsi_remove_target() has to sit behind
scsi_scan_target() due to contention over the scan_lock().
Subsequently we posted a request for comments about the deadlock:
http://marc.theaimsgroup.com/?l=linux-scsi&m=114469358829500&w=2
This posting resolves the second error. Here's what we now understand,
and are implementing:
If the lldd deletes the rport while a scan is active, the sdev's queue
is blocked which stops the issuing of commands associated with the scan.
At this point, the scan stalls, and does so with the shost->scan_mutex held.
If, at this point, if any scan or delete request is made on the host, it
will stall waiting for the scan_mutex.
For the FC transport, we queue all delete work to a single workq.
So, things worked fine when competing with the scan, as long as the
target blocking the scan was the same target at the top of our delete
workq, as the delete workq routine always unblocked just prior to
requesting the delete. Unfortunately, if the top of our delete workq
was for a different target, we deadlock. Additionally, if the target
blocking scan returned, we were unblocking it in the scan workq routine,
which really won't execute until the existing stalled scan workq
completes (e.g. we're re-scheduling it while it is in the midst of its
execution).
This patch moves the unblock out of the workq routines and moves it to
the context that is scheduling the work. This ensures that at some point,
we will unblock the target that is blocking scan. Please note, however,
that the deadlock condition may still occur while it waits for the
transport to timeout an unblock on a target. Worst case, this is bounded
by the transport dev_loss_tmo (default: 30 seconds).
Finally, Michael Reed deserves the credit for the bulk of this patch,
analysis, and it's testing. Thank you for your help.
Note: The request for comments statements about the gross-ness of the
scan_mutex still stand.

The ASL Acquire operator (17.5.1 in ACPI 3.0 spec) is allowed to time out
and return True without acquiring the semaphore. There's no indication in
the spec that this is an actual error, so this message should be
debug-only, as the message for successful acquisition is.
This used to be an ACPI_DEBUG_PRINT, but it was mis-classified as
ACPI_DB_ERROR rather than ACPI_DB_MUTEX, so it got swept up in Thomas'
recent patch to enable ACPI error messages even without CONFIG_ACPI_DEBUG.

Symbols such as PCI_USES_IO, PCI_ADDR0, etc. originated from Donald
Becker's net driver template, but have been long unused. Remove.
In a few drivers, this allows the further eliminate of the pci_flags (or
just plain flags) member in the template driver probe structure.
Most of this logic is simply open-coded in most drivers, since it never
changes.
Made a few other cleanups while I was in there, too:
* constify, __devinitdata several PCI ID tables
* replace table terminating entries such as "{0,}," and "{NULL},"
with a more-clean "{ }".
