      "message": "[PATCH] Generic ioremap_page_range: flush_cache_vmap\n\nThe existing implementation of ioremap_page_range(), which was taken\nfrom i386, does this:\n\n\tflush_cache_all();\n\t/* modify page tables */\n\tflush_tlb_all();\n\nI think this is a bit defensive, so this patch changes the generic\nimplementation to do:\n\n\t/* modify page tables */\n\tflush_cache_vmap(start, end);\n\ninstead, which is similar to what vmalloc() does. This should still\nbe correct because we never modify existing PTEs. According to\nJames Bottomley:\n\nThe problem the flush_tlb_all() is trying to solve is to avoid stale tlb\nentries in the ioremap area.  We\u0027re just being conservative by flushing\non both map and unmap.  Technically what vmalloc/vfree does (only flush\nthe tlb on unmap) is just fine because it means that the only tlb\nentries in the remap area must belong to in-use mappings.\n\nSigned-off-by: Haavard Skinnemoen \u003chskinnemoen@atmel.com\u003e\nCc: Richard Henderson \u003crth@twiddle.net\u003e\nCc: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Mikael Starvik \u003cstarvik@axis.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: \u003clinux-m32r@ml.linux-m32r.org\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Kyle McMartin \u003ckyle@parisc-linux.org\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
