2015-06-29drm/radeon: compute ring fix hibernation (CI GPU family) v2.Jérôme Glisse
In order for hibernation to reliably work we need to cleanup more thoroughly the compute ring. Hibernation is different from suspend resume as when we resume from hibernation the hardware is first fully initialize by regular kernel then freeze callback happens (which correspond to a suspend inside the radeon kernel driver) and turn off each of the block. It turns out we were not cleanly shutting down the compute ring. This patch fix that.

2015-06-29NFSv4: When returning a delegation, don't reclaim an incompatible open mode.NeilBrown
It is possible to have an active open with one mode, and a delegation for the same file with a different mode. In particular, a WR_ONLY open and an RD_ONLY delegation. This happens if a WR_ONLY open is followed by a RD_ONLY open which provides a delegation, but is then close. When returning the delegation, we currently try to claim opens for every open type (n_rdwr, n_rdonly, n_wronly). As there is no harm in claiming an open for a mode that we already have, this is often simplest. However if the delegation only provides a subset of the modes that we currently have open, this will produce an error from the server. So when claiming open modes prior to returning a delegation, skip the open request if the mode is not covered by the delegation - the open_stateid must already cover that mode, so there is nothing to do.

2015-06-29ARM: 8394/1: update memblock limit after mapping lowmemLaura Abbott
The memblock limit is currently used in find_limits to find the bounds for ZONE_NORMAL. The memblock limit may need to be rounded down a PMD size to ensure allocations are fully mapped though. This has the side effect of reducing the amount of memory in ZONE_NORMAL. Once all lowmem is mapped, it's safe to change the memblock limit back to include the unaligned section. Adjust the memblock limit after lowmem mapping is complete.

On archs where PAGE_SIZE > SGE_PAGE_SIZE it also triggers "DMA-API: device driver frees DMA memory with different size". Fix this by making the mapping and unmapping symmetric: - Do not map the whole pool page at once. Instead map the SGE_PAGE_SIZE-sized pieces individually, so they can be unmapped in the same manner. - What's mapped using dma_map_page() must be unmapped using dma_unmap_page(). Tested on ppc64.
