We do not\nseparate PKMAP_ORDER for 256K from 16K/64K PAGE_SIZE here; actually that\nvalue of 10 in support for 16K/64K had been selected rather intuitively.\nThus now for all cases of PAGE_SIZE on ppc44x (including the default, 4KB,\none) we have 512 pages for PKMAP.\n\nBecause ELF standard supports only page sizes up to 64K, then you should\nuse binutils later than 2.17.50.0.3 with \u0027-zmax-page-size\u0027 set to 256K\nfor building applications, which are to be run with the 256KB-page sized\nkernel. If using the older binutils, then you should patch them like follows:\n\n\t--- binutils/bfd/elf32-ppc.c.orig\n\t+++ binutils/bfd/elf32-ppc.c\n\n\t-#define ELF_MAXPAGESIZE 0x10000\n\t+#define ELF_MAXPAGESIZE 0x40000\n\nOne more restriction we currently have with 256KB page sizes is inability\nto use shmem safely, so, for now, the 256KB is available only if you turn\nthe CONFIG_SHMEM option off (another variant is to use BROKEN).\nThough, if you need shmem with 256KB pages, you can always remove the !SHMEM\ndependency in \u0027config PPC_256K_PAGES\u0027, and use the workaround available here:\n http://lkml.org/lkml/2008/12/19/20\n\nSigned-off-by: Yuri Tikhonov \u003cyur@emcraft.com\u003e\nSigned-off-by: Ilya Yanok \u003cyanok@emcraft.com\u003e\nSigned-off-by: Josh Boyer \u003cjwboyer@linux.vnet.ibm.com\u003e\n" }, { "commit": "8f8573ae9f5deefada6f5d64d0a52c9b39c730c7", "tree": "444d55bfb8a048ad3b13051cd55a64b688915a58", "parents": [ "37bed90094fdb1eea6e4afec6a200d4e60143e55", "0e43785c57fee50fbc00ea0378e941efb61fa0c2", "005bf0e6fa0e9543933fe2e36322af649df7cacb", "548c8933801c9ee347b6f1bad2491e4286a4f3a2" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Feb 13 11:57:18 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Feb 13 11:57:18 2009 +0100" }, "message": "Merge branches \u0027irq/genirq\u0027, \u0027irq/sparseirq\u0027 and \u0027irq/urgent\u0027 into irq/core\n" }, { "commit": "f8a6b2b9cee298a9663cbe38ce1eb5240987cb62", "tree": "b356490269c9e77d164dcc1477792b882fbb8bdb", "parents": [ "ba1511bf7fbda452138e4096bf10d5a382710f4f", "071a0bc2ceace31266836801510879407a3701fa" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Feb 13 09:44:22 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Feb 13 09:44:22 2009 +0100" }, "message": "Merge branch \u0027linus\u0027 into x86/apic\n\nConflicts:\n\tarch/x86/kernel/acpi/boot.c\n\tarch/x86/mm/fault.c\n" }, { "commit": "26456dcfb8d8e43b1b64b2a14710694cf7a72f05", "tree": "2a655c7515a5c27ea20a51a206e4d3b8df0edcba", "parents": [ "0047656e2a97d4452dd7df9e52591a7afe21a263" ], "author": { "name": "Michael Neuling", "email": "mikey@neuling.org", "time": "Thu Feb 12 19:08:58 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Feb 13 16:37:45 2009 +1100" }, "message": "powerpc/vsx: Fix VSX alignment handler for regs 32-63\n\nFix the VSX alignment handler for VSX registers \u003e 32. 32-63 are stored\nin the VMX part of the thread_struct not the FPR part.\n\nSigned-off-by: Michael Neuling \u003cmikey@neuling.org\u003e\nCC: stable@kernel.org (2.6.27 \u0026 .28 please)\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "70fe3af8403f85196bb74f22ce4813db7dfedc1a", "tree": "e82d3e5ee4b93b0a336df183d6dff5fe04cccab6", "parents": [ "d66c82ea456853a71d88359b0c19a92ac1d393ff" ], "author": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Thu Feb 12 16:12:40 2009 -0600" }, "committer": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Thu Feb 12 16:51:33 2009 -0600" }, "message": "powerpc/book-3e: Introduce concept of Book-3e MMU\n\nThe Power ISA 2.06 spec introduces a standard MMU programming model that\nis based on the Freescale Book-E MMU programing model.

The reason is that the change allows X\nto see the PCI-PCI bridge above the video card (previously it was\nobscured by the fact that there were two \"00\" directories in\n/proc/bus/pci), and the pciconfig_iobase system call on the bridge is\nfailing because of a hack that we have to return information about the\nAGP bus when X asks about bus 0. This machine doesn\u0027t have an AGP bus\n(it has PCI Express) and so the pciconfig_iobase call is returning -1,\nwhich ultimately causes X to fail to start.\n\nThis fixes it by checking that we have an AGP bridge before\nredirecting the pciconfig_iobase call to return information about the\nAGP bus.
