Hi.
I'm working on a driver for STA2X11 GPIO controller who seems to fit best to

the only problem I have is with the dir register case.
The STA2X11 has 3 registers for dir, one for data, one for set and one for

So far we never had any device registered for the SoC. This resulted in
some small issues that we kept ignoring like:

2) Lack of proper tree in the /sys/devices/
3) mips_dma_alloc_coherent() silently handling

It simply explains licensing in a way you might find helpful, as it
relates to linux.
A license without an attached interest is revocable by the owner of the
property.
The FSF require contributors to their projects to assign ownership of
the works to them: For the FSF the license is not enough.
Put two and two together.

The cond_resched() can be used to yield the CPU resource if
CONFIG_PREEMPT is not defined. Otherwise, cond_resched() is a dummy

when CONFIG_PREEMPT=y, the kernel thread needs to follow the

If a memcg is over high limit, memory reclaim is scheduled to run on
return-to-userland. However it is assumed that the memcg is the current
process's memcg. With remote memcg charging for kmem or swapping in a
page charged to remote memcg, current process can trigger reclaim on
remote memcg. So, s

Make simply skips a missing rule when it is marked as .PHONY.

The commands surrounded by ( ) are executed in a subshell, but in
most cases, we do not need to spawn an extra subshell.

You do not have to use define ... endef for filechk_* rules.
For simple cases, the use of assignment looks cleaner, IMHO.
I updated the usage for scripts/Kbuild.include in case somebody
misunderstands the 'define ... endif' is the requirement.

Now that Kbuild automatically creates asm-generic wrappers for missing
mandatory headers, it is redundant to list the same headers in
generic-y and mandatory-y.

The generic-y is redundant under the following condition:
- arch has its own implementation
- the same header is added to generated-y
- the same header is added to mandatory-y
If a redundant generic-y is found, the warning like follows is displayed:
scripts/Makefile.asm-generic:20: redund
This commit removes redundant generic-y defines in
arch/riscv/include/asm/Kbuild.
[1] It is redundant to define the same generic-y in both
arch/$(ARCH)/include/asm/Kbuild and
arch/$(ARCH)/include/uapi/asm/Kbuild.
Remove the following generic-y:
errno.h
fcntl.h
ioctl
These comments are leftovers of commit fcc8487d477a ("uapi: export all
headers under uapi directories").
Prior to that commit, exported headers must be explicitly added to
header-y. Now, all headers under the uapi/ directories are exported.

Some time ago, Sam pointed out a certain degree of overwrap between
generic-y and mandatory-y. (https://lkml.org/lkml/2017/7/10/121)
I tweaked the meaning of mandatory-y a little bit; now it defines the
minimum set of ASM headers that all architectures must have.
