Without this, a bo may get created in the cpu-inaccessible vram. Before the CP engines get setup, all copies are done via cpu memcpy. This means that the cpu tries to read from inaccessible memory, fails, and the radeon module proceeds to disable acceleration. Doing this has no downsides, as the real VRAM size gets set as soon as the CP engines get init. This is a candidate for 3.14 fixes. v2: Add comment on why the function is used Signed-off-by:

We reserve the space for the power context in stolen memory at a fixed address from a delayed work. This races with the subsequent driver init/resume code which could allocate something at that address, so the reservation for the power context fails. Reserve the space up-front, so this can't happen. This also adds a missing struct_mutex lock around the stolen allocation, which wasn't taken in the delayed work path. Signed-off-by:

Page table entries on ARM64 are 64 bits, and some pte functions such as pte_dirty return a bitwise-and of a flag with the pte value. If the flag to be tested resides in the upper 32 bits of the pte, then we run into the danger of the result being dropped if downcast. For example: gather_stats(page, md, pte_dirty(*pte), 1); where pte_dirty(*pte) is downcast to an int. This patch adds a double logical invert to all the pte_ accessors to ensure predictable downcasting. Signed-off-by:

When remapping a block to the cache's fast device that is larger than 2TB we must not truncate the destination sector to 32bits. The 32bit temporary result of from_cblock() was being overflowed in remap_to_cache() due to the logical left shift. Use an intermediate 64bit type to store the 32bit from_cblock() result to fix the overflow. Signed-off-by:
