I\nstrongly recommend that you ensure that you set an appropriate limit\nduring boot in order to guarantee that an memblock_alloc() at any time\nresults in something that is accessible with a simple __va().\n\nThe reason is that a subsequent patch will introduce the ability for\nthe array to resize itself by reallocating itself. The MEMBLOCK core will\nhonor the current limit when performing those allocations.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "27f574c223d2c09610058b3ec7a29582d63a3e06", "tree": "2689c93200504ff0d8734be50a8ca329607d8807", "parents": [ "c3f72b5706716ada7923def513486ab7bb3a5301" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Tue Jul 06 15:39:00 2010 -0700" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Aug 05 12:56:06 2010 +1000" }, "message": "memblock: Expose MEMBLOCK_ALLOC_ANYWHERE\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "c3f72b5706716ada7923def513486ab7bb3a5301", "tree": "24a7a4939164f2183bdc68212232d0a3e94274d3", "parents": [ "35a1f0bd07015dde66501b47cfb6ddc72ebe7346" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Tue Jul 06 15:38:59 2010 -0700" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Aug 05 12:56:05 2010 +1000" }, "message": "memblock: Factor the lowest level alloc function\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "35a1f0bd07015dde66501b47cfb6ddc72ebe7346", "tree": "9bfa42fd86d8fc6a6971a3b6ffcd703cc056f944", "parents": [ "b693fffb189fbfe7e1e8317ce5838808be8666a0" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Tue Jul 06 15:38:58 2010 -0700" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Aug 05 12:56:04 2010 +1000" }, "message": "memblock: Remove nid_range argument, arch provides memblock_nid_range() instead\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "b693fffb189fbfe7e1e8317ce5838808be8666a0", "tree": "432d1caa8c4a4ba9f0c76c1502af0a232bd8f62b", "parents": [ "1e2b904026e9debf95f500b8980a00c43ac0f31c" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Wed Aug 04 13:52:55 2010 +1000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Aug 05 12:56:03 2010 +1000" }, "message": "memblock: Remove memblock_find()\n\nNobody uses it anymore.
