I wrote\na small kgdb module and an accompanying gdb stub for FireWire which allows\nto gdb to talk to kgdb using remote remory reads and writes over FireWire.\n\nAn version of the gdb stub fore FireWire is able to read all global data\nfrom a system which is running a a normal kernel without any kernel debugger,\nwithout any interruption or support of the system\u0027s CPU. That way, e.g. the\ntask struct and so on can be read and even manipulated when the physical DMA\naccess is granted.\n\nA HOWTO is included in this patch, in Documentation/debugging-via-ohci1394.txt\nand I\u0027ve put a copy online at\nftp://ftp.suse.de/private/bk/firewire/docs/debugging-via-ohci1394.txt\n\nIt also has links to all the tools which are available to make use of it\nanother copy of it is online at:\nftp://ftp.suse.de/private/bk/firewire/kernel/ohci1394_dma_early-v2.diff\n\nSigned-Off-By: Bernhard Kaindl \u003cbk@suse.de\u003e\nTested-By: Thomas Renninger \u003ctrenn@suse.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "12d6f21eacc21d84a809829543f2fe45c7e37319", "tree": "6985f2370ad238fb2a568547a5049751d7c95a69", "parents": [ "9a3dc7804e9856668caef41efc54179e61ffccc0" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 30 13:33:58 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 30 13:33:58 2008 +0100" }, "message": "x86: do not PSE on CONFIG_DEBUG_PAGEALLOC\u003dy\n\nget more testing of the c_p_a() code done by not turning off\nPSE on DEBUG_PAGEALLOC.\n\nthis simplifies the early pagetable setup code, and tests\nthe largepage-splitup code quite heavily.\n\nIn the end, all the largepages will be split up pretty quickly,\nso there\u0027s no difference to how DEBUG_PAGEALLOC worked before.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "a5a19c63f4e55e32dc0bc3d936d7f94793d8b380", "tree": "3aaf621cd79889ed2658de2c30fa2fea42c86cf5", "parents": [ "6c435456dc91ace468b4e9d72ad0e13dafa22a45" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy@goop.org", "time": "Wed Jan 30 13:33:39 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 30 13:33:39 2008 +0100" }, "message": "x86: demacro asm-x86/pgalloc_32.h\n\nConvert macros into inline functions, for better type-checking.\n\nThis patch required a little bit of fiddling with headers in order to\nmake __(pte|pmd)_free_tlb inline rather than macros.\nasm-generic/tlb.h includes asm/pgalloc.h, though it doesn\u0027t directly\nuse any pgalloc definitions.

We use j_list_lock to protect the check and a\nsubsequent call to __journal_drop_transaction() and do the same in the end\nof journal_commit_transaction() which is the only place where a transaction\ncan get to T_FINISHED state.\n\nProbably I\u0027m too paranoid here and such locking is not really necessary -\ncheckpoint lists are processed only from log_do_checkpoint() where a\ntransaction must be already committed to be processed or from\n__journal_clean_checkpoint_list() where kjournald itself calls it and thus\ntransaction cannot change state either. Better be safe if something\nchanges in future...\n\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n" }, { "commit": "36df53f4a3e445175fc1e9d7f433599482ec6d7f", "tree": "1910220814219b51d0a049269758e07ec46938df", "parents": [ "abcb2947c91130426539f209f7a473a67a1f6663" ], "author": { "name": "Chris Snook", "email": "csnook@redhat.com", "time": "Mon Jan 28 23:58:27 2008 -0500" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Jan 28 23:58:27 2008 -0500" }, "message": "jbd2: Remove printk from J_ASSERT to preserve registers during BUG\n\nSigned-off-by: Chris Snook \u003ccsnook@redhat.com\u003e\nCc: \"Stephen C.
