In\nparticular, it created linear mappings for 0 and 0xC0000000 addresses\nbecause lguest used to switch to its real page tables quite late in\nboot.\n\nHowever, since d50d8fe19 Linux initialized boot page tables in\nhead_32.S even before the \"are we lguest?\" boot jump. So, now we can\nsimplify things: the Host pagetable code assumes 1:1 linear mapping\nuntil it first calls the LHCALL_NEW_PGTABLE hypercall, which we now do\nbefore we reach C code.\n\nThis also means that the Host doesn\u0027t need to know anything about the\nGuest\u0027s PAGE_OFFSET. (Non-Linux guests might not even have such a\nthing).\n\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n" }, { "commit": "61516587513c84ac26e68e3ab008dc6e965d0378", "tree": "b901d64de6588e2a50b0ac6e6855805de62eb2c8", "parents": [ "570aa13a5dbea9b905b4cd6315aa6e1b3a9fd2f8" ], "author": { "name": "Rob Landley", "email": "rob@landley.net", "time": "Fri May 06 09:27:36 2011 -0700" }, "committer": { "name": "Randy Dunlap", "email": "randy.dunlap@oracle.com", "time": "Fri May 06 09:27:55 2011 -0700" }, "message": "Correct occurrences of\n- Documentation/kvm/ to Documentation/virtual/kvm\n- Documentation/uml/ to Documentation/virtual/uml\n- Documentation/lguest/ to Documentation/virtual/lguest\nthroughout the kernel source tree.\n\nSigned-off-by: Rob Landley \u003crob@landley.net\u003e\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\n" }, { "commit": "25985edcedea6396277003854657b5f3cb31a628", "tree": "f026e810210a2ee7290caeb737c23cb6472b7c38", "parents": [ "6aba74f2791287ec407e0f92487a725a25908067" ], "author": { "name": "Lucas De Marchi", "email": "lucas.demarchi@profusion.mobi", "time": "Wed Mar 30 22:57:33 2011 -0300" }, "committer": { "name": "Lucas De Marchi", "email": "lucas.demarchi@profusion.mobi", "time": "Thu Mar 31 11:26:23 2011 -0300" }, "message": "Fix common misspellings\n\nFixes generated by \u0027codespell\u0027 and manually reviewed.\n\nSigned-off-by: Lucas De Marchi \u003clucas.demarchi@profusion.mobi\u003e\n" }, { "commit": "ced05dd741779986861fe7369fe002f542d6fa34", "tree": "506151ac3d5bc7b1f3820892773571a071366278", "parents": [ "c9f2954964df1490373065558f3156379c7a2454" ], "author": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Thu Jan 20 21:37:29 2011 -0600" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Thu Jan 20 21:37:29 2011 +1030" }, "message": "lguest: compile fixes\n\narch/x86/lguest/boot.c: In function ‘lguest_init_IRQ’:\narch/x86/lguest/boot.c:824: error: macro \"__this_cpu_write\" requires 2 arguments, but only 1 given\narch/x86/lguest/boot.c:824: error: ‘__this_cpu_write’ undeclared (first use in this function)\narch/x86/lguest/boot.c:824: error: (Each undeclared identifier is reported only once\narch/x86/lguest/boot.c:824: error: for each function it appears in.)\n\ndrivers/lguest/x86/core.c: In function ‘copy_in_guest_info’:\ndrivers/lguest/x86/core.c:94: error: lvalue required as left operand of assignment\n\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n" }, { "commit": "c9f2954964df1490373065558f3156379c7a2454", "tree": "da06a2aae32108f4e699f687308299c01e322c2e", "parents": [ "85c0647275b60380e19542d43420184e86418d86" ], "author": { "name": "Christoph Lameter", "email": "cl@linux.com", "time": "Tue Nov 30 13:07:21 2010 -0600" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Thu Jan 20 21:37:29 2011 +1030" }, "message": "lguest: Use this_cpu_ops\n\nUse this_cpu_ops in a couple of places in lguest.\n\nSigned-off-by: Christoph Lameter \u003ccl@linux.com\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n" }, { "commit": "6038f373a3dc1f1c26496e60b6c40b164716f07e", "tree": "a0d3bbd026eea41b9fc36b8c722cbaf56cd9f825", "parents": [ "1ec5584e3edf9c4bf2c88c846534d19cf986ba11" ], "author": { "name": "Arnd Bergmann", "email": "arnd@arndb.de", "time": "Sun Aug 15 18:52:59 2010 +0200" }, "committer": { "name": "Arnd Bergmann", "email": "arnd@arndb.de", "time": "Fri Oct 15 15:53:27 2010 +0200" }, "message": "llseek: automatically add .llseek fop\n\nAll file_operations should get a .llseek operation so we can make\nnonseekable_open the default for future file operations without a\n.llseek pointer.\n\nThe three cases that we can automatically detect are no_llseek, seq_lseek\nand default_llseek.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed.

This can result\nin a DNA fault while doing unlazy_fpu() in __switch_to(). This will\nend up causing a DNA fault in the context of new process thats\ngetting context switched in (as opossed to handling DNA fault in the context\nof lguest launcher/helper process).\n\nThis is wrong in both pre and post 2.6.25 kernels. In the recent\n2.6.26-rc series, this is showing up as NULL pointer dereferences or\nsleeping function called from atomic context(__switch_to()), as\nwe free and dynamically allocate the FPU context for the newly\ncreated threads. Older kernels might show some FPU corruption for processes\nrunning inside of lguest.\n\nWith the appended patch, my test system is running for more than 50 mins\nnow. So atleast some of your oops (hopefully all!) should get fixed.\nPlease give it a try.
