This\nleads to us calling phys_to_abs() twice on the physical address, which is\nseriously bogus.\n\nThis only causes a problem if the absolute address from the first translation\ncan be looked up again in the chunk_map, which depends on the size and layout\nof memory. I\u0027ve seen it fail on one box, but not others.\n\nThe minimal fix is to pass the physical address to iSeries_hpte_insert().

The problem arises when a 64-bit\nprocess maps some hugepages in the low 4GB of the address space (unusual).\nIn this case, as well as the 256M segment in question being marked for\nhugepages, other segments at 32G intervals will be incorrectly marked for\nhugepages.\n\nIn the process, this patch tweaks the semantics of the hugepage bitmaps to\nbe more sensible. Previously, an address below 4G was marked for hugepages\nif the appropriate segment bit in the \"low areas\" bitmask was set *or* if\nthe low bit in the \"high areas\" bitmap was set (which would mark all\naddresses below 1TB for hugepage). With this patch, any given address is\ngoverned by a single bitmap. Addresses below 4GB are marked for hugepage\nif and only if their bit is set in the \"low areas\" bitmap (256M\ngranularity). Addresses between 4GB and 1TB are marked for hugepage iff\nthe low bit in the \"high areas\" bitmap is set. Higher addresses are marked\nfor hugepage iff their bit in the \"high areas\" bitmap is set (1TB\ngranularity).\n\nTo avoid conflicts, this patch must be applied on top of BenH\u0027s pending\npatch for 64k base page size [0]. As such, this patch also addresses a\nhugepage problem introduced by that patch. That patch allows hugepages of\n1MB in size on hardware which supports it, however, that won\u0027t work when\nusing 4k pages (4 level pagetable), because in that case hugepage PTEs are\nstored at the PMD level, and each PMD entry maps 2MB. This patch simply\ndisallows hugepages in that case (we can do something cleverer to re-enable\nthem some other day).\n\nBuilt, booted, and a handful of hugepage related tests passed on POWER5\nLPAR (both ARCH\u003dpowerpc and ARCH\u003dppc64).\n\n[0] http://gate.crashing.org/~benh/ppc64-64k-pages.diff\n\nSigned-off-by: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c6135234550ed89a6fd0e8cb229633967e41d649", "tree": "22cef33e314839c4fb30d6fc888c0caa2a0f6602", "parents": [ "76032de898f34db55b5048349db56557828a1390", "0b154bb7d0cce80e9c0bcf11d4f9e71b59409d26" ], "author": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Nov 07 14:42:09 2005 +1100" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Nov 07 14:42:09 2005 +1100" }, "message": "Merge ../linux-2.6\n" }, { "commit": "2249ca9d60d3a8a1f6f223f0f0a0283fcb7ce33e", "tree": "33a5c8d6e2363013db1052f474c1225c472e3fcd", "parents": [ "dcad47fc423ac9f4934579af814fa2dad5c8081b" ], "author": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Nov 07 13:18:13 2005 +1100" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Nov 07 13:18:13 2005 +1100" }, "message": "powerpc: Various UP build fixes\n\nMostly this involves adding #include \u003casm/smp.h\u003e, since that defines\nthings like boot_cpuid[_phys] and [gs]et_hard_smp_processor_id, which\nare SMP-related but still needed on UP.
