[PATCH] VGA to fbcon fix.
Currently when going from vgacon to fbcon the VT screenbuffer are often
different sizes. In the case when they are different sizes a new VT
screenbuffer is allocated and the contents are copied into the new buffer.
Currently the amount copied from VGA text memory to the new screenbuf is
the size of the framebuffer console. If the framebuffer console new VT
screen buffer is greater than the VGA text memory size then we get some of
the VGA BIOS contents as well.
This patch will only allow you to copy up to the size of VGA text memory
now. The rest is filled with erase characters.

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

Does this all make sense? Clearly the __devexit section will still be in

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

[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:
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).

[PATCH] uml: add and use generic hw_controller_type->release
With Chris Wedgwood <cw@f00f.org>
Currently UML must explicitly call the UML-specific
free_irq_by_irq_and_dev() for each free_irq call it's done.
This is needed because ->shutdown and/or ->disable are only called when the
last "action" for that irq is removed.
Instead, for UML shared IRQs (UML IRQs are very often, if not always,
shared), for each dev_id some setup is done, which must be cleared on the
release of that fd. For instance, for each open console a new instance
(i.e. new dev_id) of the same IRQ is requested().
Exactly, a fd is stored in an array (pollfds), which is after read by a
host thread and passed to poll(). Each event registered by poll() triggers
an interrupt. So, for each free_irq() we must remove the corresponding
host fd from the table, which we do via this -release() method.
In this patch we add an appropriate hook for this, and remove all uses of
it by pointing the hook to the said procedure; this is safe to do since the
said procedure.
Also some cosmetic improvements are included.
This is heavily based on some work by Chris Wedgwood, which however didn't
get the patch merged for something I'd call a "misunderstanding" (the need
for this patch wasn't cleanly explained, thus adding the generic hook was
felt as undesirable).

[PATCH] ioc4: Core driver rewrite
This series of patches reworks the configuration and internal structure
of the SGI IOC4 I/O controller device drivers.
These changes are motivated by several factors:
- The IOC4 chip PCI resources are of mixed use between functions (i.e.
multiple functions are handled in the same address range, sometimes
within the same register), muddling resource ownership and initialization
issues. Centralizing this ownership in a core driver is desirable.
- The IOC4 chip implements multiple functions (serial, IDE, others not
yet implemented in the mainline kernel) but is not a multifunction
PCI device. In order to properly handle device addition and removal
as well as module insertion and deletion, an intermediary IOC4-specific
driver layer is needed to handle these operations cleanly.
- All IOC4 drivers are currently enabled by a single CONFIG value. As
not all systems need all IOC4 functions, it is desireable to enable
these drivers independently.
- The current IOC4 core driver will trigger loading of all function-level
drivers, as it makes direct calls to them. This situation should be
reversed (i.e. function-level drivers cause loading of core driver)
in order to maintain a clear and least-surprise driver loading model.
- IOC4 hardware design necessitates some driver-level dependency on
the PCI bus clock speed. Current code assumes a 66MHz bus, but the
speed should be autodetected and appropriate compensation taken.
This patch series effects the above changes by a newly and better designed
IOC4 core driver with which the function-level drivers can register and
deregister themselves upon module insertion/removal. By tracking these
modules, device addition/removal is also handled properly. PCI resource
management and ownership issues are centralized in this core driver, and
IOC4-wide configuration actions such as bus speed detection are also
handled in this core driver.
This patch:
The SGI IOC4 I/O controller chip implements multiple functions, though it is
not a multi-function PCI device. Additionally, various PCI resources of the
IOC4 are shared by multiple hardware functions, and thus resource ownership by
driver is not clearly delineated. Due to the current driver design, all core
and subordinate drivers must be loaded, or none, which is undesirable if not
all IOC4 hardware features are being used.
This patch reorganizes the IOC4 drivers so that the core driver provides a
subdriver registration service. Through appropriate callbacks the subdrivers
can now handle device addition and removal, as well as module insertion and
deletion (though the IOC4 IDE driver requires further work before module
deletion will work). The core driver now takes care of allocating PCI
resources and data which must be shared between subdrivers, to clearly
delineate module ownership of these items.

remove it. This will reduce that number of things needed to be included in
most cases to access the relevant variables.

This patch does some obvious code cleanups in the iSeries headers files.
- simplifies the bodies of lots of inline functions
- parenthesises a macros result
- removes C++ wrapping
- adds "extern" to some function declarations
There are no semantic changes.

[PATCH] ppc64: override command line AS/LD/CC variables when adding -m64 and co for biarch compilers
The following kind of calls currently fails :
make ARCH=ppc64 CC="gcc-3.4"
Since the code for detecting a biarch compiler and adding the needed 64bit
magic argument fails if the AS/LD/CC commands are overriden in the command
line.
The attached patch fixes this by using the make override and += directive,
but i am not 100% sure this will work without gmake, as i am no Makefile
expert.

[PATCH] ppc64: Abolish ioremap_mm
Currently ppc64 has two mm_structs for the kernel, init_mm and also
ioremap_mm. The latter really isn't necessary: this patch abolishes it,
instead restricting vmallocs to the lower 1TB of the init_mm's range and
placing io mappings in the upper 1TB. This simplifies the code in a number
of places and eliminates an unecessary set of pagetables. It also tweaks
the unmap/free path a little, allowing us to remove the unmap_im_area() set
of page table walkers, replacing them with unmap_vm_area().

[PATCH] ppc32: Kill embedded system.map, use kallsyms
This patch kills the whole embedded System.map mecanism and the
bootloader-passed System.map that was used to provide symbol resolution in
xmon. Instead, xmon now uses kallsyms like ppc64 does.
No hurry getting that in Linus tree, let it be tested in -mm for a while
first and make sure it doesn't break various embedded configs.

[PATCH] ppc32: Added support for all MPC8548 internal interrupts
The MPC8548 has 48 internal interrupts and 12 external interrupts. The
previous generation PowerQUICC III devices only had 32 internal and 12
external interrupts on the primary interrupt controller.
Expanded the number of internal interrupts to 48 for all PowerQUICC III
processors and moved the interrupt numbers for the external after the 48
internal interrupt lines, rather than putting the 12 new internal
interrupts at the end and ifdef'ng the whole mess. As parted of this
created a macro which represents the internal interrupt senses since they
are the same on all PQ3 processors.

I am always trying to make sure I've booted the right kernel after a new

So let's make kbuild display the compile version number at the end to give
us a hint. I know we may be booting vmlinux someday, but don't care about
it for now.
