[PATCH] pcmcia: fix sharing IRQs and request_irq without IRQ_HANDLE_PRESENT
Debugging and description from: Noah Misch <noah@cs.caltech.edu>
When a driver calls pcmcia_request_irq with IRQ_HANDLE_PRESENT unset, it looks
for an open IRQ by request_irq()ing with a dummy handler and NULL dev_info.
free_irq uses dev_info as a key for identifying the handler to free among
those sharing an IRQ, so request_irq returns -EINVAL if dev_info is NULL and
the IRQ may be shared. That unknown error code is the -EINVAL.
It looks like only pcnet_cs and axnet_cs are affected. Most other drivers let
pcmcia_request_irq install their interrupt handlers. sym53c500_cs requests
its IRQ manually, but it cannot share an IRQ.
The appended patch changes pcmcia_request_irq to pass an arbitrary, unique,
non-NULL dev_info with the dummy handler.

Unfortunately, that results in a strange, unexplainable "icbi"

[PATCH] fbdev: update info->cmap when setting cmap from user-/kernelspace.
The fb_info struct, as defined in include/linux/fb.h, contains an element
that is supposed to hold the current color map:
struct fb_cmap cmap; /* Current cmap */
This cmap is currently never updated when either fb_set_cmap() or
fb_set_user_cmap() are called. As a result, info->cmap contains the
default cmap that was set by a device driver/fbcon and a userspace
application using the FBIOGETCMAP ioctl will not always get the *currently*
used color map.
The patch fixes this by making sure the cmap is copied to info->cmap after
it is set correctly. It moves most of the code that is responsible for
setting the cmap to fb_set_cmap() and out of fb_set_user_cmap() to avoid
code-duplication.

Currently even when the cursor is disabled (`setterm -cursor off`), it is

[PATCH] DVICO Fusion DVB-T1 Tuner (LG-Z201) fix
It is a small modification to the table that defines the way that the
LG-Z201 tuner is controlled for the DVICO Fusion DVB-T1 tuner card.
I believe that a mistake was made when the dvb tuner code was reorganised
(to use a generic table for the tuner information instead of inline code)
and as a result, the DVICO card doesn't tune properly.
The modification I have made to the table makes it behave like it did with
the old inline tuner code that worked. The patch is on top of the 2.6.12
kernel.

module is integrated in can be found in [2].
This kernel module acts as a communication gateway between the linux kernel
and the hardware chip and fits the TPM-specific interfaces created by IBM in
drivers/char/tpm/tpm.h
Further information about this module and a list of succesfully tested and
therefore supported hardware can be found at our project page [3].

[PATCH] stale POSIX lock handling
I believe that there is a problem with the handling of POSIX locks, which
the attached patch should address.
The problem appears to be a race between fcntl(2) and close(2). A
multithreaded application could close a file descriptor at the same time as
it is trying to acquire a lock using the same file descriptor. I would
suggest that that multithreaded application is not providing the proper
synchronization for itself, but the OS should still behave correctly.
SUS3 (Single UNIX Specification Version 3, read: POSIX) indicates that when
a file descriptor is closed, that all POSIX locks on the file, owned by the
process which closed the file descriptor, should be released.
The trick here is when those locks are released. The current code releases
all locks which exist when close is processing, but any locks in progress
are handled when the last reference to the open file is released.
There are three cases to consider.
One is the simple case, a multithreaded (mt) process has a file open and
races to close it and acquire a lock on it. In this case, the close will
release one reference to the open file and when the fcntl is done, it will
release the other reference. For this situation, no locks should exist on
the file when both the close and fcntl operations are done. The current
system will handle this case because the last reference to the open file is
being released.
The second case is when the mt process has dup(2)'d the file descriptor.
The close will release one reference to the file and the fcntl, when done,
will release another, but there will still be at least one more reference
to the open file. One could argue that the existence of a lock on the file
after the close has completed is okay, because it was acquired after the
close operation and there is still a way for the application to release the
lock on the file, using an existing file descriptor.
The third case is when the mt process has forked, after opening the file
and either before or after becoming an mt process. In this case, each
process would hold a reference to the open file. For each process, this
degenerates to first case above. However, the lock continues to exist
until both processes have released their references to the open file. This
lock could block other lock requests.
The changes to release the lock when the last reference to the open file
aren't quite right because they would allow the lock to exist as long as
there was a reference to the open file. This is too long.
The new proposed solution is to add support in the fcntl code path to
detect a race with close and then to release the lock which was just
acquired when such as race is detected. This causes locks to be released
in a timely fashion and for the system to conform to the POSIX semantic
specification.
This was tested by instrumenting a kernel to detect the handling locks and
then running a program which generates case #3 above. A dangling lock
could be reliably generated. When the changes to detect the close/fcntl
race were added, a dangling lock could no longer be generated.

[PATCH] s390: fba dasd i/o errors
The FBA discipline does not use retries for failed requests. A request fails
after the first unsuccessful start attempt. There are some rare conditions
(e.g. CIO path recovery) in which the start of an i/o on a fba device can
fail. A tiny amount of retries is therefore reasonable.

[PATCH] s390: external call performance
The kernel uses the SIGP external call order code to signal other CPUs. When
running with dedicated CPUs external calls don't get delivered immediately but
within a fixed polling invervall. This can lead to delays where the system
appears to do nothing. Replace the SIGP external call order with the SIGP
emergency call order since this one gets delivered immediately.

[PATCH] s390: find_next_{zero}_bit fixes
The find_next_{zero}_bit primitives on s390* should never return a bit number
bigger then the bit field size. In the case of a bitfield that doesn't end on
a word boundary, an offset that makes the search start at the last word of the
bit field and the last word doesn't contain any zero/one bits the search is
continued with a call to find_first_bit with a negative size. The search
normally ends pretty quickly because the words following the bit field contain
a mix of zeros and ones. But the bit number that is returned in this case is
too big.
To fix this and additional if to check for this case is needed. To make the
code easier to read I removed the assembler parts from the
find_next_{zero}_bit functions, the C-ified code is as good.

[PATCH] s390: spin lock retry
Split spin lock and r/w lock implementation into a single try which is done
inline and an out of line function that repeatedly tries to get the lock
before doing the cpu_relax(). Add a system control to set the number of
retries before a cpu is yielded.
The reason for the spin lock retry is that the diagnose 0x44 that is used to
give up the virtual cpu is quite expensive. For spin locks that are held only
for a short period of time the costs of the diagnoses outweights the savings
for spin locks that are held for a longer timer. The default retry count is
1000.
