Fix image and color handling in atyfb_cursor()
- In the 2-bit scheme of the cursor image, just set the first bit to be
always zero (turn off transparency and/or XOR), and just do the masking
manually
- The cursor color is converted into 32-bit RGBA8888 using struct fb_cmap.
Each component in the cmap is u16 in size, so mask the upper 8 bits.

nVidia is churning out chipsets like there's no tomorrow. And even though the
pci_device_id table now has numerous entries, it is still not guaranteed that
all supported devices are included or will be included.
Fortunately, nvidiafb has chipset detection logic built in. So, change the
contents of the pci_device_id table so it will capture all nVidia devices of
the display class. Unsupported chipsets will then be filtered out by
nvidiafb's detection logic.

The EDID block should specify the display's operating limits (vertical and
horizontal sync ranges, and maximum dot clock). If not given by the EDID
block, the ranges are extrapolated from the modelist. However, the
computation used is only a rough approximation, and the resulting values may
not reflect the actual capability of the display. This problem is frequently
encountered when the EDID block has a single entry, the single mode entry will
fail validation.
To prevent this, calculate the values based on the same method used in
fb_validate_mode().

Reported by: Rich (Bugzilla Bug 6417)
"if savage driver is used in x.org together with savagefb, it results in
seriously garbled and distorted screen - coupled with severe slowdowns."
This bug is the result of Xorg unable to handle savagefb altering the
hardware which results in X failing to start properly and/or failed console
switching.
Add savagefb_state_save and savagefb_state_restore. These hooks will only
save and restore the extended VGA registers. Standard VGA registers will be
left alone. This is enough to make savagefb play nicely with the latest
Xorg savage driver, and perhaps with savage DRI. (Transient screen artifacts
may appear before X loads and during console switches).
(Unfortunately, blanking the screen also leaves Xorg in a blanked state, so I
have to unblank the screen before Xorg loads. So I doubt if the transient
screen artifacts will be completely invisible but hopefully it will only be
for a shorter duration (not much).)

in ide_dump_opcode() takes the ide_lock in an irq-unsafe manner, i.e. this
function expects to be called with irqs disabled. But
ide_dump_ata[pi]_status() doesnt do that - it enables interrupts specifically.
That is a no-no - what guarantees that another IDE port couldnt generate an
IDE interrupt while we are dumping this error? The fix is to turn the
irq-enabling in these functions into irq-disabling.

The function ide_timing_compute() fails to *actually* take drive's
specified minimum PIO/DMA cycle times into account -- when doing this, it
calls ide_timing_merge() on the 'struct ide_timing' argument which contains
garbage at the moment, and then ultimately destroys the read cycle time by
quantizing the ide_timing[] entry, instead of copying from that entry to
the argument structure, and only then doing a merge/quantize.

The interresting part of it is the "virtual address 00200200", which is
LIST_POISON2. I thought about some race condition, but as this is an UP
system, it leads to questions on how it can happen. If we look at EFLAGS:
00010202, we see that interrupts are enabled at the time of the crash
(eflags & 0x200).
Finally, I don't understand all the capi code, but I think that
handle_minor_send() is racing somehow against capi_recv_message(), which
call both capiminor_del_ack(). So if an IRQ occurs in the middle of
capiminor_del_ack() and another instance of it is invoked, it leads to
linked list corruption.
I came up with the following patch. With this, I could not reproduce the
crash anymore. Clearly, this is not the correct fix for the issue. As this
seems to be some locking issue, there might be more locking issues in that
code. For example, doesn't the whole struct capiminor have to be locked
somehow?

As part of the i386 conversion to the generic timekeeping infrastructure, this
introduces a new tsc.c file. The code in this file replaces the TSC
initialization, management and access code currently in timer_tsc.c (which
will be removed) that we want to preserve.
The code also introduces the following functionality:
o tsc_khz: like cpu_khz but stores the TSC frequency on systems that do not
change TSC frequency w/ CPU frequency
o check/mark_tsc_unstable: accessor/modifier flag for TSC timekeeping
usability
o minor cleanups to calibration math.

John's about to nuke x86's monotonic clock without grepping for it first. The
patch lamely borrows the ppc64 code for x86.
hangcheck-timer shouldn't be doing it this way
a) HAVE_MONOTONIC should be CONFIG_MONOTONIC_CLOCK and it should be defined
in arch/xxx/Kconfig.
b) That ifdef tangle shouldn't be in hangcheck-timer.c. It should be using
arch-provided helper functions, which CONFIG_MONOTONIC_CLOCK-enabling
architectures implement in arch/something.c

This patch series replaces the old non-generic Hardware Random Number
Generator support by a fully generic RNG API.
This makes it possible to register additional RNGs from modules. With this
patch series applied, Laptops with a bcm43xx chip (PowerBook) have a HW RNG
available now.
Additionally two new RNG drivers are added for the "ixp4xx" and "omap"
devices. (Written by Deepak Saxena). This patch series includes the old
patches by Deepak Saxena.
The old x86-rng driver has beed split.
The userspace RNG daemon can later be updated to select the RNG through
/sys/class/misc/hw_random/ for convenience. For now it is sufficient to use
cat and echo -n on the sysfs attributes.

Magic sysrq fails to work on many keyboards, particulary most of notebook
keyboards. This patch fixes it.
The idea is quite simple: Discard the SysRq break code if Alt is still being
held down. This way the broken keyboard can send the break code (or the user
with a normal keyboard can release the SysRq key) and the kernel waits until
the next key is pressed or the Alt key is released.

Up until now algorithms have been happy to get a context pointer since
they know everything that's in the tfm already (e.g., alignment, block
size).
However, once we have parameterised algorithms, such information will
be specific to each tfm. So the algorithm API needs to be changed to
pass the tfm structure instead of the context pointer.
This patch is basically a text substitution. The only tricky bit is
the assembly routines that need to get the context pointer offset
through asm-offsets.h.

This patch adds support for the v3020 RTC from EM Microelectronic.
The v3020 RTC is designed to be connected on a bus using only one data bit.
Since any data bit may be used, it is necessary to specify this to the
driver by passing a struct v3020_platform_data pointer (see
include/linux/rtc-v3020.h) to the driver.
Part of the following code comes from the kernel patchs produced by
Compulab for their products. The original file (available here:

Import genrtc's RTC UIE emulation (CONFIG_GEN_RTC_X) to rtc-dev driver with
slight adjustments/refinements. This makes UIE-less rtc drivers work
better with programs doing read/poll on /dev/rtc, such as hwclock. This
emulation should not harm rtc drivers with UIE support, since
rtc_dev_ioctl() calls underlaying rtc driver's ioctl() first.

This is an "RTC-framework" driver for DS1307 and similar RTC chips,
It should be a full replacement for the existing ds1337.c driver (using the
older RTC glue), giving a net increase in the number of RTC chips that work
out-of-the-box. There's a whole cluster of RTCs that are very similar, but
the 1337 driver was a bit too picky to work with most of them.
Still no support for RTC alarm IRQs (on chips that support them).

This is a patch from Alan that fixes a real ide-cd.c regression causing
bogus "Media Check" failures for perfectly valid Fedora install ISOs, on
certain CD-ROM drives.
This is a forward port to 2.6.16 (from RHEL) of the minimal changes for the
end of media problem. It may not be sufficient for some controllers
(promise notably) and it does not touch the locking so the error path
locking is as horked as in mainstream.
From: Ingo Molnar <mingo@elte.hu>
I have ported the patch to 2.6.17-rc4 and tested it by provoking
end-of-media IO errors with an unaligned ISO image. Unlike the vanilla
kernel, the patched kernel interpreted the error condition correctly with
512 byte granularity:
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown
ATAPI device hdc:
Error: Illegal request -- (Sense key=0x05)
Illegal mode for this track or incompatible medium -- (asc=0x64, ascq=0x00)
The failed "Read 10" packet command was:
"28 00 00 04 fb 78 00 00 06 00 00 00 00 00 00 00 "
end_request: I/O error, dev hdc, sector 1306080
Buffer I/O error on device hdc, logical block 163260
Buffer I/O error on device hdc, logical block 163261
Buffer I/O error on device hdc, logical block 163262
the unpatched kernel produces an incorrect error dump:
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 1306080
Buffer I/O error on device hdc, logical block 163260
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 1306088
Buffer I/O error on device hdc, logical block 163261
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 1306096
Buffer I/O error on device hdc, logical block 163262
I do not have the right type of CD-ROM drive to reproduce the end-of-media
data corruption bug myself, but this same patch in RHEL solved it.

In both the read and write cases it will return an error if
copy_{from/to}_user faults. However, I let the driver try to read/write as
much as it can just as it normally would , then finally it returns an error
if there was one. This was the most straight forward way to handle the
error , since there isn't a clear way to clean up the buffers on error .
I moved retval in idetape_chrdev_write() down into the actual code blocks
since it's really once used there, and it conflicted with my ret variable.
Fixes the following warning,
