We can save a register read operation in some case if read
expand_register first.
If info->expand_register.voltage_mask bit is set, no need to read
voltage_reg.

When setting voltage for AB8540_LDO_AUX3, current code only updates one of
info->voltage_reg and info->expand_register registers which is wrong.
To ensure we set to correct voltage, it always needs to clear or set
expand_register.voltage_mask bit of expand_register.

Hi Samuel,
Today's linux-next merge of the mfd tree got a conflict in
drivers/mfd/Kconfig between commit 3f8ec5df11aa ("[media] mfd: Add header

Log since RFC:

2. Do throttle inside wake_affine(). (thanks to PeterZ)
3. Other small fix.
Recently testing show that wake-affine stuff cause regression on pgbench, the

Now using perf tracepoint, perf output some warning message
which hard to understand what's wrong in perf.
[root@jovi perf]# ./perf stat -e timer:* ls
Warning: unknown op '{'

Actually these warning message is caused by libtraceevent format

Currently event tracing only can be use for ftrace and perf,
there don't have any mechanism to let modules(like external tracing tool)
register callback tracing function.
Event tracing implement based on tracepoint, compare with raw tracepoint,

Hi steven,
I have reworked this patchset again with minor change.
[v2 -> v3:
- change trace_descripte_t defintion in patch 3
- new patch "export ftrace_events"
- remove patch "export syscall metadata"
(syscall tracing are use same event_trace_ops backend as norma
From: "zhangwei(Jovi)"
The only caller of function ftrace(...) was removed at long time ago,
so remove the function body also.

For persistent RAM outside of main memory, the memory may have limitations
on supported accesses. For internal RAM on highbank platform exclusive
accesses are not supported and will hang the system. So atomic_cmpxchg
cannot be used. This commit uses spinlock protection for buffe
From: Rob Herring
Atomic operations are undefined behavior on ARM for device or strongly
ordered memory types. So use write-combine variants for mappings. This
corresponds to normal, non-cacheable memory on ARM. For many other
architectures, this change should not change the mapping type.

There doesn't appear to be any reason for the overall pstore RAM buffer to
be a power of 2 size, so remove it. The individual console, ftrace and oops
buffers are still a power of 2 size.

EFI variables can be flagged as being accessible only within boot services.
This makes it awkward for us to figure out how much space they use at
runtime. In theory we could figure this out by simply comparing the results
from QueryVariableInfo() to the space used by all of our variables, but
that
EFI implementations distinguish between space that is actively used by a
variable and space that merely hasn't been garbage collected yet. Space
that hasn't yet been garbage collected isn't available for use and so isn't
counted in the remaining_space field returned by QueryVariableInfo().
Combine
This reverts commit a6e4d5a03e9e3587e88aba687d8f225f4f04c792. Doing this
workaround properly requires us to work within the variable code.

Trying to run an application which was trying to put data into half
of memory using shmget(), we found that having a shmall value below
8EiB-8TiB would prevent us from using anything more than 8TiB. By setting
kernel.shmall greater that 8EiB-8TiB would make the job work.
