Previously the jz4740_wdt_set_timeout() function was starting the timer
unconditionally, even if it was stopped when that function was entered.
Now, the timer will be restarted only if it was already running before
this function is called.

OST is the OS Timer, a 64-bit timer/counter with buffered reading.
SoCs before the JZ4770 had (if any) a 32-bit OST; the JZ4770 and
JZ4780 have a 64-bit OST.
This driver will register both a clocksource and a sched_clock to the
system.

Depending on MACH_JZ47xx prevent us from creating a generic kernel that
works on more than one MIPS board. Instead, we just depend on MIPS being
set.
On other architectures, this driver can still be built, thanks to
COMPILE_TEST. This is used by automated tools to find bugs, for

I don't know who you were discussing this with...
You should CC the 0th patch to all the mailinglists. That much is a
clear rule.
For the rest

From: Shun-Chih Yu
MediaTek Command-Queue DMA controller (CQDMA) on MT6765 SoC is dedicated
to memory-to-memory transfer through queue based descriptor management.
There are only 3 physical channels inside CQDMA, while the driver is
extended to support 32 virtual channels for multiple dma users
Changes since v3:
- simplify the ISR and management on descriptors by removing tasklet and
ASYNC_TX_ENABLE_CHANNEL_SWITCH
- remove useless field in mtk_cqdma_vdesc structure
- change dev_info to dev_dbg
- fix typos
Changes since v2:
- fix build warning for kernel with DMA address in 32-bit

Document the devicetree bindings for MediaTek Command-Queue DMA controller
which could be found on MT6765 SoC or other similar Mediatek SoCs.

The actual value of the RC5 System Number (address) is stored in the
IR_READ_DATA common register masked with 0x1F00 so it have to be shifted
by 8 bits.

Subject: [PATCH] hugetlbfs: use i_mmap_rws
This patch triggers random crashes in the guest kernel on s390 early during
boot.
No migration and no setting of the balloon is involved.
