This adds a heap that allocates non-contiguous buffers that are
marked as writecombined, so they are not cached by the CPU.
This is useful, as most graphics buffers are usually not touched
by the CPU or only written into once by the CPU. So when mapping
the buffer over and over between devices,
Keep track of the heap device struct.
This will be useful for special DMA allocations
and actions.

The error-number passed into xas_set_err() should be negative. Otherwise,
the xas_error() will return 0, and grab_mapping_entry() will return the

When dax pmem is probed as RAM device on arm64, previously, kmem_start in
dev_dax_kmem_probe() should be aligned with 1G memblock size on arm64 due
to SECTION_SIZE_BITS(30).
There will be some meta data at the beginning/end of the iomem space, e.g.
namespace info and nvdimm label:
In dax pmem kmem (dax pmem used as RAM device) case, the start address
might not be aligned with PMD_SIZE

There are 3 cases when doing online pages:
- normal RAM, should be aligned with memory block size

resource
Previously, kmem_start in dev_dax_kmem_probe should be aligned with
SECTION_SIZE_BITS(30), i.e. 1G memblock size on arm64. Even with Dan
Williams' sub-section patch series, it was not helpful when adding the
dax pmem kmem to memblock:

When enabling dax pmem as RAM device on arm64, I noticed that kmem_start

1G memblock size. Even Dan Williams' sub-section patch series [1] had been
upstream merged, it was not helpful due to hard limitation of kmem_start:

The shared library build rules are currently implemented in
scripts/Makefile.host, but actually GCC-plugin is the only user of
them. Hence, they do not need to be treewide available.
Move all the relevant build rules to scripts/gcc-plugins/Makefile.
I also optimized the build steps so *.so is

If some processes in nixge_probe() fail, free_netdev(dev)
needs to be called to aviod a memory leak.

Hello,
When running rtorrent (in sync to file mode), my kernel eventually will
not write to the disk causing all access to md7 to hang and eventually the
kernel will become totally unresponsive.
EDIT: I have since gotten a response in the bug tracker and I am filing
thins to the reiserfs
I should add that in chasing down this bug I have tried all the IO
schedulers available (noop deadline and cfq). Cfq is the one I'm now
using to reproduce this.
Also, I don't know if it makes a difference, but when the system first
starts up it takes 20m to get from the login manager to having my
kunit config subcommand terminates with error if .config has a
configuration assigned with a string, for instance:
CONFIG_CC_VERSION_TEXT="gcc (distro package version) ..."
This patch adjusts the parse regex to consider such string assignments.

In ufshcd_suspend(), after clk-gating is suspended and link is set
as Hibern8 state, ufshcd_hold() is still possibly invoked before
ufshcd_suspend() returns. For example, MediaTek's suspend vops may
issue UIC commands which would call ufshcd_hold() during the command
issuing flow.
Now if

A soft deadlock occurs when call hrtimer_cancel in softirq context:
a) The main frequency of the machine is very slow
b) output->period_ns is very small, even only 1 ns
The problem can be solved in the following way: Setting a hrtimer exit flag
in the vkms_disable_vblank function
When kernel idle, system will enter wait/stop mode, wdog should continue
running in this scenario, and the refresh thread can wake up system from
wait/stop mode.

According to reference manual, the i.MX7ULP WDOG's operations should
follow below sequence:
1. disable global interrupts;
2. unlock the wdog and wait unlock bit set;
3. reconfigure the wdog and wait for reconfiguration bit set;
4. enabel global interrupts.
