This\ncaused a problem for Cell because Cell\u0027s dma_iommu_fixed_ops called\nthe dma_direct_ops if the fixed linear mapping was to be used or the\niommu ops if the dynamic window was to be used. So in order to fix\nthis problem we need to update the 64bit DMA code to use\nmap/unmap_page.\n\nFirst, we update the generic IOMMU code so that iommu_map_single()\nbecomes iommu_map_page() and iommu_unmap_single() becomes\niommu_unmap_page(). Then we propagate these changes up through all\nthe callers of these two functions and in the process update all the\ndma_mapping_ops so that they have map/unmap_page rahter than\nmap/unmap_single. We can do this because on 64bit there is no HIGHMEM\nmemory so map/unmap_page ends up performing exactly the same function\nas map/unmap_single, just taking different arguments.\n\nThis has no affect on drivers because the dma_map_single_attrs() just\nends up calling the map_page() function of the appropriate\ndma_mapping_ops and similarly the dma_unmap_single_attrs() calls\nunmap_page().\n\nThis fixes an oops on Cell blades, which oops on boot without this\nbecause they call dma_direct_ops.map_single, which is NULL.\n\nSigned-off-by: Mark Nelson \u003cmarkn@au1.ibm.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "b30115ea8f685bcd1769553fe8511745f985053c", "tree": "3bc3bbeeeaf9efbf117c87d8cda846f3206e0e46", "parents": [ "e90a13184600ec756875238ad130e2f205cd9a1b" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Mon Oct 27 19:48:47 2008 +0000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Fri Oct 31 16:13:46 2008 +1100" }, "message": "powerpc/pci: Fix unmapping of IO space on 64-bit\n\nA typo/thinko made us pass the wrong argument to __flush_hash_table_range\nwhen unplugging bridges, thus not flushing all the translations for\nthe IO space on unplug.

This part is wrong\nand is reverted by this commit.\n\nThe kernel gets a list of memory blocks and a entry point from user space.\nIts job is to copy the blocks into place and then branch to the designated\nentry point (after turning \"off\" the mmu).\n\nThe user space tool inserts a trampoline, called purgatory, that runs\nbefore the user supplied code. Its job is to establish the entry\nenvironment for the new kernel or other application based on the contents\nof memory. The purgatory code is compiled and embedded in the tool,\nwhere it is later patched using the elf symbol table using elf symbols.\n\nSince the tool knows it is creating a purgatory that will run after a\nkernel crash, it should just patch purgatory (or the kernel directly)\nif something needs to happen.\n\nSigned-off-by: Milton Miller \u003cmiltonm@bga.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "4944dd62de21230af039eda7cd218e9a09021d11", "tree": "bac70f7bab8506c7e1b0408bacbdb0b1d77262e9", "parents": [ "f17845e5d97ead8fbdadfd40039e058ec7cf4a42", "0173a3265b228da319ceb9c1ec6a5682fd1b2d92" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Oct 27 10:50:54 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Oct 27 10:50:54 2008 +0100" }, "message": "Merge commit \u0027v2.6.28-rc2\u0027 into tracing/urgent\n" }, { "commit": "5b34653963de7a6d0d8c783527457d68fddc60fb", "tree": "1a234741e1823a54cd0514616f783b4cf503a528", "parents": [ "765426e8ee4c0ab2bc9d44951f4865b8494cdbd0", "5e1b00758b5a8bee9d42515bffdaf305a32f1b04" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Oct 23 10:22:01 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Oct 23 10:22:01 2008 -0700" }, "message": "Merge branch \u0027x86/um-header\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027x86/um-header\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (26 commits)\n x86: canonicalize remaining header guards\n x86: drop double underscores from header guards\n x86: Fix ASM_X86__ header guards\n x86, um: get rid of uml-config.h\n x86, um: get rid of arch/um/Kconfig.arch\n x86, um: get rid of arch/um/os symlink\n x86, um: get rid of excessive includes of uml-config.h\n x86, um: get rid of header symlinks\n x86, um: merge Kconfig.i386 and Kconfig.x86_64\n x86, um: get rid of sysdep symlink\n x86, um: trim the junk from uml ptrace-*.h\n x86, um: take vm-flags.h to sysdep\n x86, um: get rid of uml asm/arch\n x86, um: get rid of uml highmem.h\n x86, um: get rid of uml unistd.h\n x86, um: get rid of system.h -\u003e system.h include\n x86, um: uml atomic.h is not needed anymore\n x86, um: untangle uml ldt.h\n x86, um: get rid of more uml asm/arch uses\n x86, um: remove dead header (uml module-generic.h; never used these days)\n ...\n" }, { "commit": "15adc048986f6b54b6044f2b6fc4b48f49413e2f", "tree": "f61e189b96e5065a4d091b60948fe8d9425c6df6", "parents": [ "08f5ac906d2c0faf96d608c54a0b03177376da8d" ], "author": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Thu Oct 23 09:33:08 2008 -0400" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Oct 23 16:00:25 2008 +0200" }, "message": "ftrace, powerpc, sparc64, x86: remove notrace from arch ftrace file\n\nThe entire file of ftrace.c in the arch code needs to be marked\nas notrace.

However, this change was ineffective on most pSeries\nmachines, because the RPA note added by addnote has the \"ignore me\"\nflag set to 1. This was intended to tell OF to ignore just the RPA\nnote, but has the side effect of also making OF ignore the CHRP note\n(at least on most pSeries machines).\n\nTo solve this we have to set the \"ignore me\" flag to 0 in the RPA\nnote. (We can\u0027t just omit the RPA note because that is equivalent to\nhaving an RPA note with default values, and the default values are not\nwhat we want.) However, then we have to make sure the values in the\nzImage\u0027s RPA note match up with the values that the kernel supplies\nlater in prom_init.c with either the ibm,client-architecture-support\ncall or the process-elf-header call in prom_send_capabilities().\n\nSo this sets the \"ignore me\" flag in the RPA note in addnote to 0, and\nadjusts the RPA note values in addnote.c and in prom_init.c to be\nconsistent with each other and with the values in ibm_architecture_vec.\n\nHowever, since the wrapper is independent of the kernel, this doesn\u0027t\nensure that the notes will stay consistent. To ensure that, this adds\ncode to addnote.c so that it can extract the kernel\u0027s RPA note from\nthe kernel binary and put that in the zImage. To that end, we put the\nkernel\u0027s fake ELF header (which contains the kernel\u0027s RPA note) into\nits own section, and arrange for wrapper to pull out that section with\nobjcopy and pass it to addnote, which then extracts the RPA note from\nit and transfers it to the zImage.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "41c2e949cb7b80c5a6247c7df97759953b0f71b5", "tree": "c8ba92fa5cd1dc7f6293552704e639135008c343", "parents": [ "99c840668c23fa81ac642598c792926021329747" ], "author": { "name": "Josh Poimboeuf", "email": "jpoimboe@us.ibm.com", "time": "Tue Oct 07 06:10:03 2008 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Oct 10 15:55:18 2008 +1100" }, "message": "powerpc: Fix error path in kernel_thread function\n\nThe powerpc 32-bit and 64-bit kernel_thread functions don\u0027t properly\npropagate errors being returned by the clone syscall.
