96333578b0 ACPI: add acpi_bus_removal_type in acpi_device
Add removal_type in structure acpi_device for hot removal.

ACPI_BUS_REMOVAL_EJECT is used for ACPI device hot removal.
Only one parameter is allowed in .remove method due to driver model.
So removal_type is added to indicate different removal type.

c4168bff32 ACPI: add acpi_bus_ops in acpi_device
Add acpi_bus_ops in acpi_device to support acpi hot plug.

NOTE:	Two methods .add and .start in acpi_driver.ops are
	called separately to probe ACPI devices, while only
	.probe method is called in driver model.
	As executing .add and .start separately is critical
	for ACPI device hot plug, we use acpi_bus_ops to
	distinguish different code path.

f883d9db00 ACPI: convert to sysfs framework
Setup new sysfs framework

1.	Remove /sys/firmware/acpi
2.	Add ACPI device in device tree.

File "eject" for every device that has _EJ0 method is moved from
/sys/firmware to /sys/devices.
Operation on this file is exactly the same as before.
i.e. echo 1 to "eject" will cause hot removal of this device.
Corresponding changes should be made in userspace for hot removal.

1fb8cacc19 [PATCH] Add support for Korenix 16C950-based PCI cards
This adds initial support to 8250-pci for the Korenix Jetcard PCI serial
cards.  The JC12xx cards are standard RS232-based serial cards utilising
the Oxford 16C950 device.

The JC14xx are RS422/RS485-based cards, but in order for these to be
supported natively, we will need additional tweaks to the 8250 layers so
we can specify some values for the 950's registers.  Hence, these two
entries are commented out.

And then drop a few hunks which conflicted with outstanding work.

table in which the mode lookup is done to get the index into the timing table
itself.  Get rid of the rest of the obsolete/duplicate tables and use one set

9448732f6c [PATCH] ide: fix HPT37x timing tables
Fix/remove bad/unused timing tables: HPT370/A 66 MHz tables weren't really
needed (the chips are not UltraATA/133 capable and shouldn't support 66 MHz
PCI) and had many modes over- and underclocked, HPT372 33 MHz table was in
fact for 66 MHz and 50 MHz table missed UltraDMA mode 6, HPT374 33 MHz table
was really for 50 MHz...  (Actually, HPT370/A 33 MHz tables also have issues.
e.g.  HPT370 has PIO modes 0/1 overlocked.)

There's also no need in the separate HPT374 tables because HPT372 timings
should be the same (and those tables has UltraDMA mode 6 which HPT374 supports
depending on HPT374_ALLOW_ATA133_6 #define)...

836c0063c7 [PATCH] ide: HPT3xxN clocking fixes
Fix serious problems with the HPT372N clock turnaround code:

- the wrong ports were written to when called for the secondary channel;

- it didn't serialize access to the channels;

- turnaround shou;dn't be done on 66 MHz PCI;

- caching the clock mode per-channel caused it to get out of sync with the
  actual register value.

Additionally, avoid calibrating PLL twice (for each channel) as the second try
results in a wrong PCI frequency and thus in the wrong timings.

Make the driver deal with HPT302N and HPT371N correctly -- the clocking and
(seemingly) a need for clock tunaround is the same as for HPT372N.  HPT371/N
chips have only one, secondary channel, so avoid touching their "pure virtual"
primary channel, and disable it if the BIOS haven't done this already.

Also, while at it, disable UltraATA/133 for HPT372 by default -- 50 MHz DPLL
clock don't allow for this speed anyway.  And remove the traces of the former
bad patch that wasn't even applicable to this version of driver.

Has been tested on HPT370/371N, unfortunately I don't have an instant access
to the other chips...

34f8f0a5e9 [PATCH] tty: remove useless memory barrier
I don't see why there is a memory barrier in copy_from_read_buf() at all.
Even if it was useful spin_unlock_irqrestore implies a barrier.

cd86128088 [PATCH] Fix numerous kcalloc() calls, convert to kzalloc()
All kcalloc() calls of the form "kcalloc(1,...)" are converted to the
equivalent kzalloc() calls, and a few kcalloc() calls with the incorrect
ordering of the first two arguments are fixed.

5d6f647fc6 [PATCH] debug: add sysrq_always_enabled boot option
Most distributions enable sysrq support but set it to 0 by default.  Add a
sysrq_always_enabled boot option to always-enable sysrq keys.  Useful for
debugging - without having to modify the disribution's config files (which
might not be possible if the kernel is on a live CD, etc.).

Also, while at it, clean up the sysrq interfaces.

872225ca77 [PATCH] cciss: remove calls to pci_disable_device
Remove calls to pci_disable_device except in fail_all_cmds.  The
pci_disable_device function does something nasty to Smart Array controllers
that pci_enable_device does not undo.  So if the driver is unloaded it
cannot be reloaded.

Also, customers can disable any pci device via the ROM Based Setup Utility
(RBSU).  If the customer has disabled the controller we should not try to
blindly enable the card from the driver.  Please consider this for
inclusion.

When CONFIG_PCI is not defined (i.e.  PCI bus is disabled), the sx driver

The pcd, pwt, and pat bits on page table entries affect the cpu cache.  Since
the cache is a host resource, the guest should not be able to control it.
Moreover, the meaning of these bits changes depending on whether pat is
enabled or not.

So, force these bits to zero on shadow page table entries at all times.
