Its filename is sh-drop-__pxd_offset-macros-that-duplicate-pxd_index-ones.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/sh-drop-__pxd_offset-macros-that-duplicate-pxd_index-ones.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/sh-drop-__pxd_offset-macros-that-duplicate-pxd_index-ones.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Mike Rapoport Subject: sh: drop __pXd_offset() macros that duplicate pXd_index() ones 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.
