The following patch will use dio/aio to submit IO to backing file,

For non-AIO case, single thread has been used for long long time,
and it was just converted to work in v4.0, which
There are about 3 advantages to use direct I/O and AIO on

pinning pages
3) avoid context switch for obtaining good throughput

This patches provides two approaches for enabling direct IO
from user space:
- userspace(such as losetup) can pass 'file' which is
opened/fcntl as O_DIRECT
- sysfs file is provided to run dio tests easily
Also __loop_update_dio() is introduced to check if direct I/O
can be
It doesn't make sense to enable merge because the I/O
submitted to backing file is handled page by page.

When direct IO is submitted from kernel, it is often unnecessary
to dirty pages, for example of loop, dirtying pages have been
considered in the upper filesystem(over loop) side already, and
they don't need to be dirtied again.

Hi Linus,

I think raid5 is all working nicely again now.
I think there is still a race somewhere in starting the recovery thread, but
it is minor and I suspect I'll have it nailed soon. Not quite this week

Add the driver for on-chip UART used on UniPhier SoCs.
This hardware is similar to 8250, but the register mapping is
slightly different:
- The offset to FCR, MCR is different.
- The divisor latch access bit does not exist. Instead, the
divisor latch register is available at offset 9.

While the KERN_DEBUG output is fast, accounce_cpu() uses KERN_INFO,
which goes to the (serial) console by default.
One would expect it to drain at about 10 bits/byte / 115200 baud = 87us/byte.

Create an irq_chip for each GIO block. Uses chained IRQ handling since
known uses of this block have a BCM7120 L2 interrupt controller as a
parent. Supports interrupts for all GPIOs.
In the IRQ handler, we check for raised IRQs for invalid GPIOs and warn
(ratelimited) if they're encountered.

Out of the brcmstb SoCs that I know, BCM3390 has the largest numbers
of GPIOs, with its
- 320 "peripheral" GPIOs
- 5*32 = 160 UPG GPIOs (counting unused lines, which do get counted)
- 2*32 = 64 UPG AON GPIOs (counting unused lines)
Total: 544
I suspect that the upper limit will only need to be hig
Several drivers (e.g. gpio-keys) allow for GPIOs to be configured as
wakeup sources, and this GPIO controller supports that through a
separate interrupt path.
The de-facto standard DT property "wakeup-source" is checked, since
that indicates whether the GPIO controller hardware can wake. Uses

Some brcmstb GPIO controllers can be used to wake from suspend, so use the
de facto standard property 'wakeup-source' to mark the nodes of controllers
with that capability.
Also document interrupts-extended, which will be used for wakeup handling
because the interrupt parent for the wake IRQ is di
This adds support for the GPIO IP "UPG GIO" used on Broadcom STB SoCs

from 0, so any GPIO e
This patchset adds support for the GPIO controller (UPG GIO) used on Broadcom's
various BRCMSTB SoCs (BCM7XXX and others). It uses the "basic-mmio-gpio"
interface to try to reduce duplication of the base logic.

Hi6220 is one mobile solution of Hisilicon, this patchset contains
initial support for Hi6220 SoC and HiKey development board, which
supports octal ARM Cortex A53 cores. Initial support is minimal and
includes just the arch configuration, clock driver, device tree
configuration
Hisilicon does some performance enhancements based on PL011(e.g. larger
FIFO length), so add one compatible string "hisilicon,hi6220-uart" for
future optimisations or workarounds works.
