On HPPA there exists some older GSC graphics cards, which need special
graphic-card-BIOS patching to become supported. Since we don't have yet
implemented the patching, it's better to detect such cards in advance,
inform to the user that there are known problems and to not activate the
card.
Problematic GSC cards and BIOS versions are:
* Hyperdrive/Hyperbowl (A4071A) graphics card series:
* ID = 0x2BCB015A (Version 8.04/8)
* ID = 0x2BCB015A (Version 8.04/11)
* Thunder 1 VISUALIZE 48 card:
* ID = 0x2F23E5FC (Version 8.05/9)
* Thunder 2 VISUALIZE 48 XP card:
* ID = 0x2F8D570E (Version 8.05/12)
* Some Hyperion and ThunderHawk GSC cards
Further details are described here:

The class_device->device conversion is causing an oops in revalidate

It seems cdrwtool in the udftools has been unusable on "modern" kernels
for some time. A Google search reveals many people with the same issue
but no solution (cdrwtool fails to format the disk). After spending some
time tracking down the issue, it comes down to the following:
The udftools still use the older CDROM_SEND_PACKET interface to send
things like FORMAT_UNIT through to the drive. They should really be
updated, but that's another story. Since most distros are using libata
now, the cd or dvd burner appears as a SCSI device, and we wind up in
block/scsi_ioctl.c. Here, the code tries to take the "struct
cdrom_generic_command" and translate it and stuff it into a "struct
sg_io_hdr" structure so it can pass it to the modern sg_io() routine
instead. Unfortunately, there is one error, or rather an omission in the
translation. The timeout that is passed in in the "struct
cdrom_generic_command" is in HZ=100 units, and this is modified and
correctly converted to jiffies by use of clock_t_to_jiffies(). However,
a little further down, this cgc.timeout value in jiffies is simply
copied into the sg_io_hdr timeout, which should be in milliseconds.
Since most modern x86 kernels seems to be getting build with HZ=250, the
timeout that is passed to sg_io and eventually converted to the
timeout_per_command member of the scsi_cmnd structure is now four times
too small. Since cdrwtool tries to set the timeout to one hour for the
FORMAT_UNIT command, and it takes about 20 minutes to format a 4x CDRW,
the SCSI error-handler kicks in after the FORMAT_UNIT completes because
it took longer than the incorrectly-calculated timeout.

The wrong version of the "teach dataflash about binary density" patch
just got merged (v2 not v3) ... this restores the missing updates:
* Fix the cmdlinepart *regression* that caused testing failures (!!)
by restoring the original part labels in relevant cases.
* Don't reference things that don't exist (!)
- An opcode that doesn't even exist for DataFlash
- The part is "at45db642" not "at45db641"
- ID zero in this JEDEC table
* Make the JEDEC probe routine report and handle errors better:
- If the SPI calls fail, return the error codes.
- Don't depend on ordering of table entries.
- Unrecognized ids are different from parts that have no ID.
We won't actually know how to handle them correctly; display
the ID and ignore the chip.
* Move the original block comment about the "legacy" chip ID scheme
back next to the code to which it applies ... not next to the new
JEDEC query code, which uses an entirely different strategy.
* Don't print a guessed erasesize; /proc/mtd has the real value.

Bug report from Steven Jan Springl:
Issuing the following command causes a kernel oops:
tc qdisc add dev eth0 handle ffff: ingress
The problem mostly stems from all of the special case handling of
ingress qdiscs.
So, to fix this, do the grafting operation the same way we do for TX
qdiscs. Which means that dev_activate() and dev_deactivate() now do
the "qdisc_sleeping <--> qdisc" transitions on dev->rx_queue too.
Future simplifications are possible now, mainly because it is
impossible for dev_queue->{qdisc,qdisc_sleeping} to be NULL. There
are NULL checks all over to handle the ingress qdisc special case
that used to exist before this commit.

This adds the regulator framework core.
This framework is designed to provide a generic interface to voltage
and current regulators within the Linux kernel. It's intended to
provide voltage and current control to client or consumer drivers and
also provide status information to user space applications through a
sysfs interface.
The intention is to allow systems to dynamically control regulator
output in order to save power and prolong battery life. This applies
to both voltage regulators (where voltage output is controllable) and
current sinks (where current output is controllable).
This framework safely compiles out if not selected so that client
drivers can still be used in systems with no software controllable
regulators.

This interface is for machine specific code and allows the creation of
voltage/current domains (with constraints) for each regulator. It can
provide regulator constraints that will prevent device damage through
overvoltage or over current caused by buggy client drivers. It also

Add support to allow consumer device drivers to control their regulator
power supply.
This uses a similar API to the kernel clock interface in that consumer
drivers can get and put a regulator (like they can with clocks atm) and
get/set voltage, current limit, mode, enable and disable. This should
allow consumers complete control over their supply voltage and current
limit. This also compiles out if not in use so drivers can be reused in
systems with no regulator based power control.

Given a hosed SELinux config in which a system never loads policy or
disables SELinux we currently just return -EINVAL for anyone trying to
read /proc/mounts. This is a configuration problem but we can certainly
be more graceful. This patch just ignores -EINVAL when displaying LSM
options and causes /proc/mounts display everything else it can. If
policy isn't loaded the obviously there are no options, so we aren't
really loosing any information here.
This is safe as the only other return of EINVAL comes from
security_sid_to_context_core() in the case of an invalid sid. Even if a
FS was mounted with a now invalidated context that sid should have been
remapped to unlabeled and so we won't hit the EINVAL and will work like
we should. (yes, I tested to make sure it worked like I thought)
