That's correct for ppc64el, but I never signed up for the powerpc port. > I don't know about the user base, but I think most of the *development* > effort and sponsorship of the powerpc ports now comes from IBM, and > unfortunately they don't care about PowerMacs. IBM doesn't really care about the powerpc port either, they do about the ppc64el port. That said I have tracked the change to 64kB pages to the following commit: | commit aed63a56b189d771116f2d4b8fe10bbec528e6a2 | Author: Bastian Blank <waldi@debian.org> | Date: Sat Aug 9 19:42:11 2014 +0000 | | * debian/changelog: Update | * debian/config/kernelarch-powerpc/config-arch-64: Set PPC_64K_PAGES. | * debian/config/kernelarch-powerpc/config-arch-64-le: Remove overriden option. | | svn path=/dists/trunk/linux/; revision=21721 I don't really know what it has been done, so I have Cced Bastian so that he can comment on that. It's something that can be reverted if needed I guess. Aurelien -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurelien@aurel32.net http://www.aurel32.net
