Subject: [PATCH 2/3] mips: drop __pXd_offset() macros that duplicate pXd_index() ones
From: Mike Rapoport <rppt@...ux.ibm.com>
The __pXd_offset() macros are identical to the pXd_index() macros and there
is no point to keep both of them. All architectures define and use
pXd_index() so let's keep only those to make mips consistent with the rest
of the kernel.
