Dave Airlie 0c76be3519 drm/r300: fix bug in r300 userspace hardware wait emission
This interface was originally designed wrong, confusing bit-fields and
integers, major brown paper bag going back many years...

But userspace only ever used 4 values so fix the interface for new
users and fix the implementation to deal with the 4 values userspace
has ever emitted (0x1, 0x2, 0x3, 0x6).

Stephen Neuendorffer 4c58f8fe2e [POWERPC] Xilinx: hwicap: Verify sync before reading idcode.
It appears that in some cases, the sync word might not be recognized
by the hardware correctly.  If this happens, then attempting to read
from the port results in an unrecoverable error because of the design
of the FPGA core.  This patch updates the code to check the status of
the device before reading the IDCODE, in order to avoid entering this
unrecoverable state.  This patch also adds additional NOOP commands
into the sychronization sequence, which appears to be necessary to
avoid the condition on some hardware.

Both the buffer-based and fifo-based icap cores have a status

transactions have completed.  However, the status can be useful to the
main driver as well.  This patch exposes these status functions to the
main driver along with some masks for the differnet bits.

David Brownell 537878d2c9 hw_random doc updates
Update documentation for the hw_random support to be current:

 - Documentation/hw_random.txt has been updated to reflect the
   current code:  it's a framework now, a "core" with a small
   sysfs interface, that hardware-specific drivers plug in to.
   Text specific to Intel hardware is now at the end.

 - Kconfig now references the Documentation/hw_random.txt file
   and better explains what this really does.

Both chunks of documentation now higlight the fact that the kernel entropy
pool is maintained by "rngd", and this driver has nothing directly to do with
that important task.

unsigned long != __le32, TYVM, and unsigned char[4] is not guaranteed

While we are at it, sanitize sOutDW() a bit - have it take Byte_t * and
handle dereferencing internally.

NB: sWriteTxPrioByte() is almost certainly buggered on big-endian and is
missing cpu_to_le16() on assignments to *WordPtr; I've left it alone for now.

Mike Isely 9df5808cca drm: Fix race that can lockup the kernel
The i915_vblank_swap() function schedules an automatic buffer swap
upon receipt of the vertical sync interrupt.  Such an operation is
lengthy so it can't be allowed to happen in normal interrupt context,
thus the DRM implements this by scheduling the work in a kernel
softirq-scheduled tasklet.  In order for the buffer swap to work
safely, the DRM's central lock must be taken, via a call to
drm_lock_take() located in drivers/char/drm/drm_irq.c within the
function drm_locked_tasklet_func().  The lock-taking logic uses a
non-interrupt-blocking spinlock to implement the manipulations needed
to take the lock.  This semantic would be safe if all attempts to use
the spinlock only happen from process context.  However this buffer
swap happens from softirq context which is really a form of interrupt
context.  Thus we have an unsafe situation, in that
drm_locked_tasklet_func() can block on a spinlock already taken by a
thread in process context which will never get scheduled again because
of the blocked softirq tasklet.  This wedges the kernel hard.

To trigger this bug, run a dual-head cloned mode configuration which
uses the i915 drm, then execute an opengl application which
synchronizes buffer swaps against the vertical sync interrupt.  In my
testing, a lockup always results after running anywhere from 5 minutes
to an hour and a half.  I believe dual-head is needed to really
trigger the problem because then the vertical sync interrupt handling
is no longer predictable (due to being interrupt-sourced from two
different heads running at different speeds).  This raises the
probability of the tasklet trying to run while the userspace DRI is
doing things to the GPU (and manipulating the DRM lock).

The fix is to change the relevant spinlock semantics to be the
interrupt-blocking form.  After this change I am no longer able to
trigger the lockup; the longest test run so far was 20 hours (test
stopped after that point).

Note: I have examined the places where this spinlock is being
employed; all are reasonably short bounded sequences and should be
suitable for interrupts being blocked without impacting overall kernel
interrupt response latency.

In commit e6bafba5b4 ("wmi: (!x & y)

This is not tested and clearly changes the semantics, so it is only
something to consider.

Arjan van dev Ven fcea424d31 fix historic ioremap() abuse in AGP
Several AGP drivers right now use ioremap_nocache() on kernel ram in order
to turn a page of regular memory uncached.

There are two problems with this:

    1) This is a total nightmare for the ioremap() implementation to keep
       various mappings of the same page coherent.

    2) It's a total nightmare for the AGP code since it adds a ton of
       complexity in terms of keeping track of 2 different pointers to
       the same thing, in terms of error handling etc etc.

This patch fixes this by making the AGP drivers use the new
set_memory_XX APIs instead.

Note: amd-k7-agp.c is built on Alpha too, and generic.c is built
on ia64 as well, which do not yet have the set_memory_*() APIs,
so for them some we have a few ugly #ifdefs - hopefully they'll
be fixed soon.

select strikes again. ipwireless selects PPP which in turn tries to select
SLHC, both of which are technically "protected" by an if NETDEVICES
in drivers/net/Kconfig. This leads to .config hilarity, with net suddenly
ending up in the SCSI menu:

	#
	# SCSI device support
	#
	# CONFIG_SCSI_DMA is not set
	# CONFIG_SCSI_NETLINK is not set
	CONFIG_PPP=y
	# CONFIG_PHONE is not set

Curiously the SLHC select from PPP doesn't seem to happen, as there's no
CONFIG_SLHC=y (only CONFIG_PPP=y gets set) -- Kconfig bug? Caught with a
randconfig.

The device is manufactured by IPWireless.  In some countries (for
example Czech Republic, T-Mobile ISP) this card is shipped for service
called UMTS 4G.

It's a piece of PCMCIA "4G" UMTS PPP networking hardware that presents
itself as a serial character device (i.e.  looks like usual modem to
userspace, accepts AT commands, etc).

Jesper Juhl a96ca105a6 mga_dma: return 'err' not just zero from mga_do_cleanup_dma()
While reading some code I stumbled across the use of 'err' in
drivers/char/drm/mga_dma.c::mga_do_cleanup_dma() and I think there's a small
problem.

The variable is only used inside #if __OS_HAS_AGP which is fine, but all that
ever happens is an assignment to the variable - it is never actually used for
anything.  The variable is nicely initialized to zero which is also what the
return statement at the end of function returns (always at the moment).

It looks to me like that function should be returning 'err' instead of always
just returning 0.  Here's a patch to do that.

Joe Peterson 54d2a37eda Fix IXANY and restart after signal (e.g. ctrl-C) in n_tty line discipline
Fix two N_TTY line discipline issues related to resuming a stopped TTY
(typically done with ctrl-S):

1) Fix handling of character that resumes a stopped TTY (with IXANY)

With "stty ixany", the TTY line discipline would lose the first character
after the stop, so typing, for example, "hi^Sthere" resulted in "hihere"
(the 't' would cause the resume after ^S, but it would then be thrown away
rather than processed as an input character).  This was inconsistent with
the behavior of other Unix systems.

2) Fix interrupt signal (e.g. ctrl-C) behavior in stopped TTYs

With "stty -ixany" (often the default), interrupt signals were ignored
in a stopped TTY until the TTY was resumed with the start char (typically
ctrl-Q), which was inconsistent with the behavior of other Unix systems.

Turn on INTR/QUIT/SUSP echoing in the N_TTY line discipline (e.g.  ctrl-C

Linux seems to be the only unix-like OS (recently I've verified this on
Solaris, BSD, and Mac OS X) that does *not* behave this way, and I really
miss this as a good visual confirmation of the interrupt of a program in
the console or xterm.  I remember this fondly from many Unixs I've used
over the years as well.  Bringing this to Linux also seems like a good way
to make it yet more compliant with standard unix-like behavior.

interrupts.  These have been taken into account.

This allows us to remove CONFIG_BROKEN_ON_SMP.  Completely untested.

Stephen Neuendorffer ef141a0bb0 [POWERPC] Xilinx: hwicap driver
This includes code for new fifo-based xps_hwicap in addition to the
older opb_hwicap, which has a significantly different interface.  The
common code between the two drivers is largely shared.

Significant differences exists between this driver and what is
supported in the EDK drivers.  In particular, most of the
architecture-specific code for reconfiguring individual FPGA resources
has been removed.  This functionality is likely better provided in a
user-space support library.  In addition, read and write access is
supported.  In addition, although the xps_hwicap cores support
interrupt-driver mode, this driver only supports polled operation, in
order to make the code simpler, and since the interrupt processing
overhead is likely to slow down the throughput under Linux.

Olof Johansson ecb8a8472f pcmcia: convert some internal-only ioaddr_t to unsigned int
Convert the io_req_t members to unsigned int, to allow use on machines with
more than 16 bits worth of IO ports (i.e.  secondary busses on ppc64, etc).

There was only a couple of places in drivers where a change was needed.  I
left printk formats alone (there are lots of %04x-style formats in there),
mostly to not change the format on the platforms that only have 16-bit io
addresses, but also because the padding doesn't really add all that much value
most of the time.

I found only one sprintf of an address, and upsized the string accordingly (I
doubt anyone will have anywhere near INT_MAX as irq value, but at least
there's room for it now).

Dave Airlie 4d64dd9e5d intel-agp: fixup resource handling in flush code.
The flush code resource handling was having problems where some BIOS
reserve the resource in a pnp block and some don't.

Also there was a bug in that configure was being called at resume
and resetting some of the structs.

Julia Lawall 91d361c279 agp: remove unnecessary pci_dev_put
pci_get_class implicitly does a pci_dev_put on its second argument, so
pci_dev_put is only needed if there is a break out of the loop.

The semantic match detecting this problem is as follows:

// <smpl>
@@
expression dev;
expression E;
@@

* pci_dev_put(dev)
  ... when != dev = E
(
* pci_get_device(...,dev)

* pci_get_device_reverse(...,dev)

serue@us.ibm.com 62f29babbc agp: remove uid comparison as security check
In the face of containers and user namespaces, a uid==0 check for
security is not safe.  Switch to a capability check.

I'm not sure I picked the right capability, but this being AGP
CAP_SYS_RAWIO seemed to make sense.

Dave Airlie 2162e6a2b0 agp/intel: Add chipset flushing support for i8xx chipsets.
This is a bit of a large hammer but it makes sure the chipset is flushed
by writing out 1k of data to an uncached page. We may be able to get better
information in the future on how to this better.

Dave Airlie 6c00a61e1b intel-agp: add chipset flushing support
This adds support for flushing the chipsets on the 915, 945, 965 and G33
families of Intel chips.

The BIOS doesn't seem to always allocate the BAR on the 965 chipsets
so I have to use pci resource code to create a resource

It adds an export for pcibios_align_resource.

Dave Airlie a13af4b4d8 agp: add chipset flushing support to AGP interface
This bumps the AGP interface to 0.103.

Certain Intel chipsets contains a global write buffer, and this can require
flushing from the drm or X.org to make sure all data has hit RAM before
initiating a GPU transfer, due to a lack of coherency with the integrated
graphics device and this buffer.

This just adds generic support to the AGP interfaces, a follow-on patch
will add support to the Intel driver to use this interface.
