Thanks for your benchmark. It's very helpful to see the benchmark on
different environments.
Use bit fields, and the size of struct ftrace_event_field can be
shrunk from 48 bytes to 40 bytes on 64bit kernel.

init_syscall_trace() can be called during kernel bootup only, so we can
mark it and the functions it calls as __init.

Hi all,
Today's linux-next merge of the net-next tree got a conflict in

identification for gso packets") from Linus' tree and commit c54419321455

When running with 4096 cores attemping to read /proc/timer_list will fail
with an ENOMEM condition. On a sufficantly large systems the total amount
of data is more then 4mb, so it won't fit into a single buffer. The

Split timer_list_show_tickdevices() out the header and just pull the rest up
to timer_list_show. Also tweak the location of the whitespace. This is all
to prep for the fix.

On systems with 4096 cores attemping to read /proc/timer_list
fails because we are trying to push all the data into a single
kmalloc buffer.
A better solution is to not us the single_open mechanism but to
provide our own seq_operations and treat each cpu as an
individual record.

Okay, here it is. The result is compile-tested.
Changes since v1:
* Remove the module-export for unmap_kernel_range and make zsmalloc
built-in instead

I applied all 16 of the sfc patches on top of 3.5.7.8 and the result
passed our standard 'overnight' test suite for in-tree drivers.

Hi,
The comment of struct ab8500_regulator_info says the delay means
"startup/set voltage delay in us".
I'm confused by the meaning, does it mean enable_time or set_voltage_time_sel
time or both?

These should be good for the IOAT DMA devices on the Intel Atom S1269,
S1279, and S1289 platforms. We are also adding IOAT v3.3 definition for
the new DMA engine.
