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.

drivers: dma-coherent: Fix typo in dma_mmap_from_coherent documentation

The function documentation incorrectly references dma_release_coherent.
Fix it. Don't mention a specific function name as dma_mmap_from_coherent
as multiple callers.

PM / Domains: Fix memory leak on error path in pm_genpd_attach_cpuidle

firmware loader: sync firmware cache by async_synchronize_full_domain

2012-10-22T15:37:18+00:00

async.c has provided synchronization mechanism on async_schedule_*,
so use async_synchronize_full_domain to sync caching firmware instead
of reinventing the wheel.

firmware loader: let direct loading back on 'firmware_buf'

2012-10-22T15:37:17+00:00

Firstly 'firmware_buf' is introduced to make all loading requests
to share one firmware kernel buffer, so firmware_buf should
be used in direct loading for saving memory and speedup firmware
loading.

Secondly, the commit below

	abb139e75c2cdbb955e840d6331cb5863e409d0e(firmware:teach
	the kernel to load firmware files directly from the filesystem)

introduces direct loading for fixing udev regression, but it
bypasses the firmware cache meachnism, so this patch enables
caching firmware for direct loading case since it is still needed
to solve drivers' dependency during system resume.

firmware loader: fix one reqeust_firmware race

2012-10-22T15:37:17+00:00

Several loading requests may be pending on one same
firmware buf, and this patch moves fw_map_pages_buf()
before complete_all(&fw_buf->completion) and let all
requests see the mapped 'buf->data' once the loading
is completed.
