As ux500 is being converted to timer based delay loops, and the timer
used is not depending on CPUs clock frequency, set cpufreq_driver flag
CPUFREQ_CONST_LOOPS to prevent cpufreq rescaling loops_for_jiffies.

Hi all,
this implements timer-based delay support for nomadik and ux500
platforms, using the MTU as time source, and marks the u8500 cpufreq
driver as CPUFREQ_CONST_LOOPS accordingly.
The patches are based on Arnd's arm-soc/ux500/mtu-clk branch, as that
contains latest MTU driver developments,

When a memory is added, we update zone's and pgdat's start_pfn and
spanned_pages in the function __add_zone(). So we should revert them
when the memory is removed.
The patch adds a new function __remove_zone() to do this.

It is usually accepted that code should explain itself.
The max size of string is 1025(512*2 + 1) bytes so there is
no point to add one more byte for string allocation.
This patch is intended to fix incorrect size for string allocation

This will allow to use gpio for chip select with no modification in the
driver binding
When use the cs-gpios, the gpio number will be passed via the cs_gpio field
and the number of chip select will automatically increased.

It is usually accepted that code should explain itself.
The max size of string is 1025(512*2 + 1) bytes so there is
no point to add one more byte for string allocation.
This patch is intended to fix incorrect size for string allocation
and make code more readable.

Doesn't this have an off-by-one error?
True.

instead?
Yes, I'll fix this.

I conducted a few experiments with a workload to compare the following

Thanks!
This is a real showstopper for me, it occurs in every session now.
Booting with i915.i915_enable_rc6=0 doesn't help either..

I am not sure this has something with kernel. But the system I just

Main idea here - we never flash last (struct tty_buffer) in the
active buffer. Only data for ldisc. (tty-buf.head-read =
tty-buf.head-commit). At that moment driver can collect(write) data
in buffer without conflict.

Looks good to me. Would be nice to keep a copy of the test that shows
