That's the second version of the series introducing USER_PGTABLES_CEILING and defining it to TASK_SIZE on ARM.
Russell, do you ack these patches (or let me know if you have further comments)? I think it's better if they go upstream together rather than one via akpm and the other via the arm tree.
Thanks.
Changes from v1: - Only defining USER_PGTABLES_CEILING to TASK_SIZE when CONFIG_ARM_LPAE is enabled. The classic ARM MMU uses the default ceiling 0. - Improved commit log stating that the shared page table freeing is already handled by pgd_free() for the ARM LPAE case. - Cc'ed stable (starting with 3.3 when ARM LPAE was merged).
Catalin Marinas (1): arm: Set the page table freeing ceiling to TASK_SIZE
Hugh Dickins (1): mm: Allow arch code to control the user page table ceiling
