Good morning.
I have a custom PCI device that needs to fill memory buffers of up to 16MB
in size. For various reasons I would like to avoid implementing
scatter-gather support in the device and would much rather prefer a
contiguous buffer view instead. The buffers are allocated using

As commit 5ba800962a80 ("kbuild: update ARCH alias info for sparc")
addressed, SPARC accepts ARCH=sparc32 as an alias.
However, arch/sparc/Makefile wrongly sets KBUILD_DEFCONFIG, then
sparc64_defconfig is chosen as the base configuration for ARCH=sparc32.

Convert modem related GPIO setup from integer space to GPIO descriptors.
Also, restore original initialization order of the MODEM device and its
related GPIO pins.
Cleanup of MODEM relaated regulator setup is postponed while waiting for

Don't request MODEM IRQ GPIO by its global number in
ams_delta_modem_init(). Instead, obtain its GPIO descriptor
and assign related IRQ to the MODEM. Do that from
omap_gpio_deps_init(), where the chip is already looked up. Then, in
ams_delta_modem_init(), just check for the IRQ number having
Amstrad Delta MODEM device used to be initialized at arch_initcall
before it was once moved to late_initcall by commit f7519d8c8290 ("ARM:
OMAP1: ams-delta: register latch dependent devices later"). The purpose
of that change was to postpone initialization of devices which depended
on latch2 pins
Latch2 pins control a number of on-board devices, namely LCD, NAND,
MODEM and CODEC. Those pins used to be initialized with safe values
from init_machine before that operation was:
1) moved to late_initcall in preparation for conversion of latch2 to
GPIO device - see commit f7519d8c8290 ("ARM:

Hm, I thought we've finished this part of discussion, no?
Anyway, let me repeat my position: I don't like the interface
you've proposed in that follow-up patchset, and I explained why.

The Yocto build system does a 'make clean' when rebuilding due to
changed dependencies, and that consistently fails for me (causing the
whole BSP build to fail) with errors such as

This is the second version of a patch that improves the error message of
the perf events parser when the PMU hardware does not support address
filters.
Previously, the perf returned the following error:

The newly added 'llvm.opts' variable allows passing options directly to

Store a decompression ID in 'struct kmod_path', so it can be later
stored in 'struct dso'.
Switch 'struct kmod_path's 'comp' from 'bool' to 'int' to return the
compressions array index. Add 0 index item into compressions array, so
that the comp usage stays as it was: 0 - no
