The hotkey events and ACPI handles used for detecting tablet mode on a

For whatever reason, the X1 Yoga doesn't support the normal method of
querying for tablet mode. Instead of providing the MHKG method under the
hotkey handle, we're instead given the CMMD method under the EC handle.
Values on this handle are either 0x1, laptop mode, or 0x6, tablet mode.

This patch adds support for the "amcc,usb-otg" device
which is found in the PowerPC Canyonlands' dts.
The device definition was added by:
commit c89b3458d8cc ("powerpc/44x: Add USB DWC DTS entry to Canyonlands board")'
but without any driver support as the dwc2 driver wasn't
available at that time
This patch moves the the host_dma initialization
before dwc2_set_param_dma_desc_enable and
dwc2_set_param_dma_desc_fs_enable. The reason being
that both function need it.

"rtc: implement read loop in "C" vs. inline asm" was a bug fix which is

"gfrc: boot print alongside other timers" squashed in
The original distinction was done as they were developed at different
times and primarily because they are specific to UP (RTC) and SMP (GFRC).
But given that driver handles that at runtime, (i.e. not allowing
RTC as clocksource in SMP), we can simplify things a bit.

Currently pstore has a global spinlock for all zones. Since the zones
are independent and modify different areas of memory, there's no need
to have a global lock, so we should use a per-zone lock as introduced
here. Also, when ramoops's ftrace use-case has a FTRACE_PER_CPU fl

In preparation for merging the per CPU buffers into one buffer when
we retrieve the pstore ftrace data, we store the timestamp as a
counter in the ftrace pstore record. We store the CPU number as well
if !PSTORE_CPU_IN_IP, in this case we shift the counter and may lose
order

PMSG now uses ramoops_pstore_write_buf_user() instead of ...write_buf().

Currently ramoops_init_przs() is hard wired only for panic dump zone
array. In preparation for the ftrace zone array (one zone per-cpu) and pmsg
zone array, make the function more generic to be able to handle this case.
Heavily based on similar work from Joel Fernandes.

Hi Joel,
I've reorganized a bunch of the logic here. Since pstore is going to need
the init_przs() logic for multiple pmsg przs, I wanted to get this in and
make sure I was happy with how it looks. I figured this would reduce our
round-trip time on reviews. :)
Can you test this series and verify

Up until this patch, each of the per CPU ftrace buffers appear as a
separate ftrace-ramoops-N file. In this patch we merge all the zones into
one and populate a single ftrace-ramoops-0 file.

When setting ramoops record sizes, sometimes it's not clear which
parameters contributed to the allocation failure. This adds a per-zone

If the RAMOOPS_FLAG_FTRACE_PER_CPU flag is passed to ramoops pdata, split
the ftrace space into multiple zones depending on the number of CPUs.
This speeds up the performance of function tracing by about 280% in my
tests as we avoid the locking. The trade off being lesser sp
