VMware reported the performance regression during memmap_init() invocation.
And they bisected to commit 73a6e474cb376 ("mm: memmap_init: iterate over
memblock regions rather that check each PFN") causing it.
The current memmap_init_zone() only handles memory region inside one zone,
actually memmap_init() does the memmap init of one zone. So rename both of
them accordingly.
And also rename the function parameter 'range_start_pfn' and local variable
'range_end_pfn' of memmap_init() to
As David suggested, simply passing 'struct zone *zone' is enough. We can

In real use of dynamic-resolution-change it is observed that the
LAST buffer flag (which marks the last decoded buffer with the
resolution before the resolution-change event) is not reliably set.
Fix this by set the LAST buffer flag on next queued capture buffer
after the resolution-change event.
Hi,
Changes since v1:
* In 1/5
- clear next_buf_last flag before session_continue in vdec_start_capture
- on event, flush output buffers unconditiannly
* Added two more patches from Alex (4/5) and Fritz (5/5)
v1 can be found at: https://www.spinics.net/lists/linux-media/msg177801.html
From: Alexandre Courbot
DRC events can happen virtually at anytime, including when we are
starting a seek. Should this happen, we must make sure to return to the
DRC state, otherwise the firmware will expect buffers of the new
resolution whereas userspace will still work with the old one.
From: Fritz Koenig
If the DRC is near the end of the stream the client
may send a V4L2_DEC_CMD_STOP before the DRC occurs.
V4L2_DEC_CMD_STOP puts the driver into the
VENUS_DEC_STATE_DRAIN state. DRC must be aware so
that after the DRC event the state can be restored
correctly.

Remove shareable bit for ordering barrier, just keep ordering
in current hart is enough for SMP. Using three continuous
sync.is as PTW barrier to prevent speculative PTW in 860

There are two implementation of spinlock in arch/csky:
- simple one (NR_CPU = 1,2)
- tick's one (NR_CPU = 3,4)
Remove the simple one.
There is already smp_mb in spinlock, so remove the definition of
smp_mb__after_spinlock.

I would guess that for csky, this is a mistake, as the architecture

The c610, c807, c810 don't support SMP, so futex_cmpxchg_enabled = 1

It looks like compiler optimization is smart enough to know that
assigning zero is unnecessary after clear_siginfo() which is memset()
under the hood. At least in my x86_64 machine, w/ or w/o this patch,
there is no difference in final compiled machine code. (I've compared

The macro htons expands to __swab16 which has special
case for constants in little endian case. In big
endian case both __constant_htons and htons macros
expand to the same code. So, replace __constant_htons
with htons to get rid of the definition of __constant_htons
completely.

If QCA6391 chip (connected to PCIe0) is not powered at the PCIe probe
time, PCIe0 bus probe will timeout and the device will not be detected.
To ease device power up support, use qca639x as pcie0 phy power-domain.
This allows us to make sure that QCA6391 chip is powered on before PCIe0
probe
Qualcomm QCA639x is a family of WiFi + Bluetooth chips, with BT part
being controlled through the UART and WiFi being present on PCIe
bus. Both blocks share common power sources wich should be turned on
before either of devices can be probed. Declare common 'qca639x' driver
