The 32-bit hash code didn't need it so far so we don't update
mm->cpu_vm_mask on context switch. This however breaks the
merge of the RCU based page table freeing and other upcoming
32-bit embedded SMP work.

This patch adds support for page sizes bigger than 4K (16K/64K) on
PPC 44x.
PGDIR table is much smaller than page in case of 16K/64K pages (512
and 32 bytes resp.) so we allocate PGDIR with kzalloc() instead of
__get_free_pages().
PTE table covers rather big memory area in case of 16K/64K pages

Well, there are still some issues concerning coding-style and design,
but those can be worked out, I guess. Still, there is one conceptual

See below, I just copied the original
This function is alike to the simple of_get_gpio(), but accepts new
argument: flags. This new function will be used by the drivers that
need to retrieve additional GPIO information, such as active-low flag.

Add one more compatible string to the table for
of_platform binding, so that the platforms, which
have the SysACE chip on board (e.g. Katmai), could
describe it in their device trees correctly.

Hello,
I would like to use async DMA driver to transfer data. I find no function to
wait for the end of the DMA transfer in blocking mode:
the only way to get the end of the transfer is the polling by the function
"dma_async_is_tx_complete".
To wait the end of the transfer, must I poll the trans

Since the QPACE (Chromodynamics Parallel Computing on the

have PCI devices and a MPIC much lesser setup and

as OF device. A notifier func

All,
is anybody working on some improvements regarding configurable I2C
frequency inside the i2c-mpc driver ?
If not - would anybody be intersted in getting this done, i.e.
configurable via device tree ?

In pseries_dedicated_idle_sleep(), if we need to exit idle during the
snooze period (i.e. need_resched or cpu has been offlined), then we should
re-disable the interrupts and clear TIF_POLLING_NRFLAG before leaving.

Use resource_size_t for physical address of SystemACE
chip. This fixes the driver brokeness for 32 bit systems
with 64 bit resources (e.g. PPC440SPe).
Also this patch adds one more compatible string for more
clean description of the hardware, and fixes a sector_t-
related compilation warning.

ibmebus_free_irq() frees the IRQ but does not remove its mapping which
results in stale entries in the map.
Fix this by adding a call to irq_dispose_mapping() in ibmebus_free_irq().

Currently, pseries_cpu_die() calls msleep() while polling RTAS for
the status of the dying cpu.
However if the cpu that is going down also happens to be the one doing
the tick then we're hosed as the tick_do_timer_cpu 'baton' is only passed
later on in tick_shutdown() when _cpu_down() does th
