Applied to powerpc next, thanks. https://git.kernel.org/powerpc/c/5c3c7ede2bdcb85fa2fd51c814 I reworded one comment a little, from: /* 2^11 PTEGS / 2^18 bytes is the minimum htab size permitted * by the architecture */ to: /* * 2^11 PTEGS of 128 bytes each, ie. 2^18 bytes is the minimum htab * size permitted by the architecture. */ To avoid any confusion about the "/" referring to division. cheers
