Under the conditions that UML uses it, tcgetattr is guaranteed to return
-EINTR when the console is attached to /dev/ptmx, making generic_console_write
hang because it loops, calling tcgetattr until it succeeds. This is a host
bug - see http://marc.info/?l=linux-kernel&m=119618990807182&w=2 for the
details.
This patch works around it by blocking SIGIO while the terminal attributes are
being fiddled.

The inet_diag register fix broke inet_diag module loading because the
loaded module had to take the same mutex that's already held by the
loader in order to register the new handler.
This patch fixes it by introducing a separate mutex to protect the

This reverts commit a2b51812a4dc5db09ab4d4638d4d8ed456e2457e.
It turns out that this change caused some machines to fail to come
back up when being rebooted, and generated an error in the hypervisor
error log on some machines. The platform architecture (PAPR) is a
little unclear on exactly when the RTAS ibm,os-term function should be
called. Until that is clarified I'm reverting this commit.

Changed resolution of named references in packages
Fixed a problem with the Package operator where all named
references were created as object references and left otherwise
unresolved. According to the ACPI specification, a Package can
only contain Data Objects or references to control methods. The
implication is that named references to Data Objects (Integer,
Buffer, String, Package, BufferField, Field) should be resolved
immediately upon package creation. This is the approach taken
with this change. References to all other named objects (Methods,
Devices, Scopes, etc.) are all now properly created as reference objects.

Commit cfb5285660aad4931b2ebbfa902ea48a37dfffa1 removed a useful feature for
us, which provided a cpu accounting resource controller. This feature would be
useful if someone wants to group tasks only for accounting purpose and doesnt
really want to exercise any control over their cpu consumption.
The patch below reintroduces the feature. It is based on Paul Menage's
original patch (Commit 62d0df64065e7c135d0002f069444fbdfc64768f), with
these differences:
- Removed load average information. I felt it needs more thought (esp
to deal with SMP and virtualized platforms) and can be added for
2.6.25 after more discussions.
- Convert group cpu usage to be nanosecond accurate (as rest of the cfs
stats are) and invoke cpuacct_charge() from the respective scheduler
classes
- Make accounting scalable on SMP systems by splitting the usage
counter to be per-cpu
- Move the code from kernel/cpu_acct.c to kernel/sched.c (since the
code is not big enough to warrant a new file and also this rightly
needs to live inside the scheduler. Also things like accessing
rq->lock while reading cpu usage becomes easier if the code lived in
kernel/sched.c)
The patch also modifies the cpu controller not to provide the same accounting
information.
Tested-by: Balbir Singh <balbir@linux.vnet.ibm.com>
Tested the patches on top of 2.6.24-rc3. The patches work fine. Ran
some simple tests like cpuspin (spin on the cpu), ran several tasks in
the same group and timed them. Compared their time stamps with
cpuacct.usage.

sata_mv: Fix broken Marvell 7042 support.
The Marvell 7042 chip is more or less the same as the 6042 internally,
but sports a PCIe bus. Despite having identical SATA cores, the 7042
does differ from its PCI bus counterparts in placment and layout of
certain bus related registers.
This patch fixes sata_mv to distinguish between the PCI bus registers
of earlier chips, and the PCIe bus registers of the 7042.
Specifically, move the offsets and bit patterns for the
PCI/PCIe interrupt cause/mask registers into the struct mv_host_priv,
as these values differ between the 6xxx and 7xxx series chips.
This fixes the driver to not access reserved PCI addresses,
and prevents the lockups reported in linux-2.6.24 with 7042 boards.
Also add a new PCI ID for the Highpoint 2300 7042-based board
that I'm using for testing this stuff here.
Tested with Marvell 6081 + 7042 chips, on x86 & x86_64.

Several fixes for the AVR32 PATA driver:
* Updated to use new AVR32 SMC timing API. This removes the need for "magic"
constants in signal timing.
* Removed the ATA_FLAG_PIO_POLLING, the driver should use interrupts.
* Removed .port_disable and .irq_ack as these are no longer needed.
* Improved some comments.

The smc911x.h is a bit of a mess, not supporting any sort of generic
configuration. For the moment only ARCH_PXA and SH_MAGIC_PANEL_R2 have
suitable definitions, so we reflect this in the Kconfig also.
While there are other SH boards that will likely turn this on in the
2.6.25 time frame, it's not worth trying to stub around at the moment.
Fixes up the allmodconfig build, as noted by akpm.

Using PCIE advanced error recovery stuff creates more user problems than it's worth.
The AER stuff depends on MMCONFIG and in many configurations it just doesn't work.
Plus it doesn't add any real functionality to the driver. The sky2
