Its filename is ia64-use-asm-generic-cacheflushh.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/ia64-use-asm-generic-cacheflushh.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/ia64-use-asm-generic-cacheflushh.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: Christoph Hellwig Subject: ia64: use asm-generic/cacheflush.h IA64 needs almost no cache flushing routines of its own. Rely on asm-generic/cacheflush.h for the defaults.
