Applied, thanks.
When directory iterate and lookup is called, there is a buggy rewinding
of start point for traversing fat chain to the directory entry's first
cluster. This caused repeated fat chain traversing from the first entry
of the directory that would show worse performance if huge amounts of
files exist un
While the ARM architectural timer is generatlly the best timer to use,
a non-c3stop timer is needed for cpuidle. Use the sun4i timer for this
purpose, which is present on all 64-bit sunxi SoCs.

In preparation for adding CPU idle states, hook up the sun4i timer.
Having a non-c3stop clockevent source available is necessary for all
CPUs to simultaneously enter a local-timer-stop idle state.

The sun50i SoCs contain timer blocks which are useful as broadcast
clockevent sources. They each have 2 interrupts, matching the A23
variant, so add the new compatible strings with the A23 compatible
as a fallback.

For a CPU to enter an idle state, there must be some timer which can
trigger an IRQ to wake it back up. The local ARM architectural timer is
not sufficient, because that timer stops when the CPU is powered down.
Some other CPU's ARM architectural timer can be used, but this prevents
that other CPU
Nodes should be sorted by unit address. Move the watchdog node to the
correct place, so it will be next to the timer node when that is added.

The sun4i timer IP block has a variable number of interrupts based on
the compatible. Use enums to combine the two sections for the existing
3-interrupt variants, and to simplify adding new compatible strings.

Hi,
We tried to run some performance tests to build the case and the numbers
really did not support much.
So at this point to time we decided that IOCTL support is not making sense.

We needn't retrieve the memory slot again in user_mem_abort() because
the corresponding memory slot has been passed from the caller. This
would save some CPU cycles. For example, the time used to write 1GB
memory, which is backed by 2MB hugetlb pages and write-protected, is
dropped by 6.8% from 928
The last (IPA) page can't be specified when a new memory slot is
added. The error -EFAULT is returned when the memory slot is added
with the following parameters for the VM, which has 40-bits IPA
limit. The host has 4KB base page size. It's not correct because
the last (IPA) page is still usable.
find_vma_intersection() has been existing to search the intersected
vma. This uses the function where it's applicable, to simplify the
code.

The series includes several minior improvements to stage-2 page fault
handler: PATCH[1/2] are cleaning up the code. PATCH[3] fixes the address
range check on adding new memory slot. PATCH[4] don't retrieve the memory
slot again in the page fault handler to save a bit CPU cycles.

Degradation of write speed caused by frequent disk access for cluster
bitmap update on every cluster allocation could be improved by
selective syncing bitmap buffer. Change to flush bitmap buffer only
