[ALSA] cs4236-irq-handling-fix.patch
CS4236+ driver
Background: The card/chipset supports an external MIDI interrupt. By
default, this interrupt isn't used (because the isapnp mechanism chooses a
configuration without an assigned interrupt). If the user wishes to
explicitly select an interrupt via the mpu_irq parameter for such a
configured device, it doesn't work: The driver always shows:
isapnp MPU: port=0x330, irq=-1
(note the 'irq=-1')
Problem: The driver only allows to set the irq if pnp_irq_valid returns
true for this particular pnp device. This, however, is only true if an
interrupt has already been assigned (pnp_valid_irq returns true if the flag
IORESOURCE_IRQ is set and IORESOURCE_UNSET is not set). If no interrupt
has been assigned so far, IORESOURCE_UNSET is set and pnp_irq_valid returns
false, thereby inhibiting the selection of a valid irq.
Solution: Don't check for a valid (= already assigned) irq at the point of
calling pnp_resource_change.
Tested successfully on Linux 2.6.11.

[PATCH] md: optimised resync using Bitmap based intent logging
With this patch, the intent to write to some block in the array can be logged
to a bitmap file. Each bit represents some number of sectors and is set
before any update happens, and only cleared when all writes relating to all
sectors are complete.
After an unclean shutdown, information in this bitmap can be used to optimise
resync - only sectors which could be out-of-sync need to be updated.
Also if a drive is removed and then added back into an array, the recovery can
make use of the bitmap to optimise reconstruction. This is not implemented in
this patch.
Currently the bitmap is stored in a file which must (obviously) be stored on a
separate device.
The patch only provided infrastructure. It does not update any personalities

[PATCH] md: merge md_enter_safemode into md_check_recovery
md_enter_safemode checks if it is time to mark the md superblock as 'clean'.
i.e. if all writes have completed and a suitable delay has passed.
This is currently called from md_handle_safemode which in-turn is called
(almost) every time md_check_recovery is called, and from the end of
md_do_sync which causes the mddev->thread to run, which will always call
md_check_recovery as well.
So it doesn't need to be a separate function and fits quite well into
md_check_recovery.
The "almost" is because multipathd calls md_check_recovery but not
md_handle_safemode. This is OK because the code from md_enter_safemode is a
no-op if mddev->safemode == 0, which it always is for a multipathd (providing
we don't allow it to be set to 2 on a signal...)

s1d13xxxfb_remove() is referenced from s1d13xxxfb_probe(), which is marked

Does this all make sense? Clearly the __devexit section will still be in
core when the __devinit code is run, if the driver was loaded as a module.
But I suppose that if the driver is statically linked, the __devexit section
might be dropped early in boot. Still, we wouldn't drop __devexit prior to
initcall completion, at which point the __devinit code has all been run
anyway.
verdict: this code was legal and made sense. Is this a generic problem, or an

[PATCH] isofs: show hidden files, add granularity for assoc/hidden files flags
The current isofs treatment of hidden files is flawed in two ways. First,
it does not provide sufficient granularity; it hides both 'hidden' files
and 'associated' files (resource fork for Mac files). Second, the default
behavior to completely strip hidden files, while an admirable
implementation of the spec, is a poor choice given the real world use of
hidden files as a poor mans copy protection scheme for MSDOS and Windows
based systems. A longer description of this is available here:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0205.3/0267.html
This patch was originally built after a few private conversations with Alan
Cox; I shamefully failed to persist in seeing it go forward, I hope to make
amends now.
This patch introduces granularity by allowing explicit control for both
hidden and associated files. It also reverses the default so that by
default, hidden files are treated as regular files on the iso9660 file
system.
This allow Wine to process Windows CDs, including those that are hybrid
Mac/Windows CDs properly and completely, without our having to go muck up
peoples fstabs as we do now. (I have tested this with such a hybrid +
hidden CD and have verified that this patch works as claimed).

Note that the kernel can still overindex the buffer due to the variable size
of the rock-ridge directory entries. We cannot check that in rock_continue()

For browsable autofs maps, a mount request that arrives at the same time an
expire is happening can fail to perform the needed mount.
This happens becuase the directory exists and so the revalidate succeeds when
we need it to fail so that lookup is called on the same dentry to do the
mount. Instead lookup is called on the next path component which should be
whithin the mount, but the parent isn't mounted.

no directory creation (at mount time) is needed for browsable mount entries.

32767 MB. The memory size is contained in a structure created by an sclp
call. The kernel accesses the field with a LH instrution which performs a
sign extension of a 16 bit word. In the case of a memory size with bit 2^15
set this results in a very large value and the memory detection just loops for
a long time. In addition if more then 64 GB are used on a 64 bit system the
memory size is read from an incorrect storage location.
Use zero-extention to read the 16 bit memory size and the correct offset to
read the 4 byte memory size on 64 bit.

[PATCH] uml: fix linkage of tt mode against NPTL
With Al Viro <viro@parcelfarce.linux.theplanet.co.uk>
To make sure switcheroo() can execute when we remap all the executable
image, we used a trick to make it use a local copy of errno... this trick
does not work with NPTL glibc, only with LinuxThreads, so use another
(simpler) one to make it work anyway.
Hopefully, a lot improved thanks to merging with the version of Al Viro
(which had his part of problems, though, i.e. removing a fix to another
bug and not fixing the problem on i386).
