__ioremap() took a set of page table flags (specifically the cacheable
and bufferable bits) to control the mapping type. However, with
the advent of ARMv6, this is far too limited.
Replace the page table flags with a memory type index, so that the
desired attributes can be selected from the mem_type table.
Finally, to prevent silent miscompilation due to the differing
arguments, rename the __ioremap() and __ioremap_pfn() functions.

Currently the iop3xx platform support code assumes that RedBoot is the
bootloader and has already initialized the ATU. Linux should handle this
initialization for three reasons:
1/ The memory map that RedBoot sets up is not optimal (page_to_dma and
virt_to_phys return different addresses). The effect of this is that using
the dma mapping API for the internal bus dma units generates pci bus
addresses that are incorrect for the internal bus.
2/ Not all iop platforms use RedBoot
3/ If the ATU is already initialized it indicates that the iop is an add-in
card in another host, it does not own the PCI bus, and should not be
re-initialized.

This patch removes the unnecessary bit number from CKENnn_XXXX
definitions for PXA, so that
CKEN0_PWM0 --> CKEN_PWM0
CKEN1_PWM1 --> CKEN_PWM1
...
CKEN24_CAMERA --> CKEN_CAMERA
The reasons for the change of these defitions are:
1. they do not scale - they are currently valid for pxa2xx, but
definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera
instead of bit 24
2. they are unnecessary - the peripheral name within the definition
has already announced its usage, we don't need those bit numbers
to know which peripheral we are going to enable/disable clock for
3. they are inconvenient - think about this: a driver programmer
for pxa has to remember which bit in the CKEN register to turn
on/off
Another change in the patch is to make the definitions equal to its
clock bit index, so that
#define CKEN_CAMERA (24)
instead of
#define CKEN_CAMERA (1 << 24)
this change, however, will add a run-time bit shift operation in
pxa_set_cken(), but the benefit of this change is that it scales
when bit index exceeds 32, e.g., pxa3xx has two registers CKENA
and CKENB, totally 64 bit for this, suppose CAMERA clock enabling
bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10)
and so that pxa_set_cken() need minimum change to adapt to that.

Reposted patch for kernel 2.6.21-rc2.
The driver i2c-pxa doesn't set the class member in i2c_adapter, which
is used to register the I2C adapter. The hwmon (sensors) drivers (e.g.
adm1021) that are connected to a i2c-pxa adapter don't attach because
they expect that the adapter supports class I2C_CLASS_HWMON.
This patch adds functionality to allow platforms to set the class and
pass it as platform_data to the i2c-pxa driver. Sample usage in
platform code:
static struct i2c_pxa_platform_data my_i2c_platform_data = {
.class = I2C_CLASS_HWMON
};
static void __init my_platform_init(void)
{
(void) platform_add_devices(devices, ARRAY_SIZE(devices));
pxa_set_i2c_info(&my_i2c_platform_data);

This is not a deadlock actually, as neighbor table's proxy_queue

Lockdep thinks there is a deadlock as both queues are initialized
with skb_queue_head_init() and thus have a common class.

If the writebacks are cancelled via nfs_cancel_dirty_list, or due to the
memory allocation failing in nfs_flush_one/nfs_flush_multi, then we must
ensure that the PG_writeback flag is cleared.
Also ensure that we actually own the PG_writeback flag whenever we
schedule a new writeback by making nfs_set_page_writeback() return the
value of test_set_page_writeback().
The PG_writeback page flag ends up replacing the functionality of the
PG_FLUSHING nfs_page flag, so we rip that out too.

ide: add "optical" to sysfs "media" attribute
ide: ugly messages trying to open CD drive with no media present
ide: correctly prevent IDE timer expiry function to run if request was already handled
It is possible for the timer expiry function to run even though the
request has already been handled: ide_timer_expiry() only checks that
the handler is not NULL, but it is possible that we have handled a
request (thus clearing the handler) and then started a new request
(thus starting the timer again, and setting a handler).
A simple way to exhibit this is to set the DMA timeout to 1 jiffy and
run dd: The kernel will panic after a few minutes because
ide_timer_expiry() tries to add a timer when it's already active.
To fix this, we simply add a request generation count that gets
incremented at every interrupt, and check in ide_timer_expiry() that
we have not already handled a new interrupt before running the expiry
function.

Since lazy MMU batching mode still allows interrupts to enter, it is
possible for interrupt handlers to try to use kmap_atomic, which fails when
lazy mode is active, since the PTE update to highmem will be delayed. The
best workaround is to issue an explicit flush in kmap_atomic_functions
case; this is the only way nested PTE updates can happen in the interrupt
handler.
