Thanks for clarification. 64 bit alignment fix and the allocation range checksOn Monday 03 December 2012 09:16 PM, Vitaly Andrianov wrote:This patch fixes a couple of bugs that otherwise impair CMA functionality on
- alignment must be a 64-bit type when running on systems with 64-bit
physical addresses. If this is not the case, the limit calculation thunks
allocations down to an address range < 4G.
- The allocated range check is removed. On 32bit ARM kernel with LPAE
enabled the base may be allocated outside the fist 4GB of physical
memory (keystone SoC for example).

the two fixes separate patches.
They are all related to the very same issue, and what the whole patch
does is change the type used to store physical addresses from unsigned
long to phys_addr_t. This is really a single change.
