firmware: Make user-mode helper optional

2013-02-04T01:57:40+00:00

This patch adds a new kconfig, CONFIG_FW_LOADER_USER_HELPER, and
guards the user-helper codes in firmware_class.c with ifdefs.

Yeah, yeah, there are lots of ifdefs in this patch.  The further
clean-up with code shuffling follows in the next.

drivers/base: remove CONFIG_EXPERIMENTAL

2012-10-25T18:55:45+00:00

This config item has not carried much meaning for a while now and is
almost always enabled by default. As agreed during the Linux kernel
summit, remove it.

drivers: cma: Fix wrong CMA selected region size default value

2012-10-23T12:05:33+00:00

Kconfig lists CMA_SIZE_SEL_ABSOLUTE as the default value fo the CMA
selected region size, but that option isn't available in the defined
choices. Set the default to CMA_SIZE_SEL_MBYTES instead.

mm: factor out memory isolate functions

2012-08-01T01:42:45+00:00

mm/page_alloc.c has some memory isolation functions but they are used only
when we enable CONFIG_{CMA|MEMORY_HOTPLUG|MEMORY_FAILURE}.  So let's make
it configurable by new CONFIG_MEMORY_ISOLATION so that it can reduce
binary size and we can check it simple by CONFIG_MEMORY_ISOLATION, not if
defined CONFIG_{CMA|MEMORY_HOTPLUG|MEMORY_FAILURE}.

drivers: add Contiguous Memory Allocator

2012-05-21T13:09:37+00:00

The Contiguous Memory Allocator is a set of helper functions for DMA
mapping framework that improves allocations of contiguous memory chunks.

CMA grabs memory on system boot, marks it with MIGRATE_CMA migrate type
and gives back to the system. Kernel is allowed to allocate only movable
pages within CMA's managed memory so that it can be used for example for
page cache when DMA mapping do not use it. On
dma_alloc_from_contiguous() request such pages are migrated out of CMA
area to free required contiguous block and fulfill the request. This
allows to allocate large contiguous chunks of memory at any time
assuming that there is enough free memory available in the system.

This code is heavily based on earlier works by Michal Nazarewicz.

drivers/base: add bus for System-on-Chip devices

2012-02-10T19:42:25+00:00

Traditionally, any System-on-Chip based platform creates a flat list
of platform_devices directly under /sys/devices/platform.

In order to give these some better structure, this introduces a new
bus type for soc_devices that are registered with the new
soc_device_register() function.  All devices that are on the same
chip should then be registered as child devices of the soc device.

The soc bus also exports a few standardised device attributes which
allow user space to query the specific type of soc.

dma-buf: drop option text so users don't select it.

cpu: Register a generic CPU device on architectures that currently do not

2012-01-11T23:50:11+00:00

frv, h8300, m68k, microblaze, openrisc, score, um and xtensa currently
do not register a CPU device.  Add the config option GENERIC_CPU_DEVICES
which causes a generic CPU device to be registered for each present CPU,
and make all these architectures select it.

Richard Weinberger  covered UML and suggested using
per_cpu.

dma-buf: mark EXPERIMENTAL for 1st release.

2012-01-06T10:20:30+00:00

Mark dma-buf buffer sharing API as EXPERIMENTAL for first release.
We will remove this in later versions, once it gets smoothed out
and has more users.
