Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.
Let it rip!

jffs2: Improve post-mount CRC scan efficiency We need to finish doing the CRC checks before we can allow writes to happen, and we currently process the inodes in order. This means a call to jffs2_get_ino_cache() for each possible inode# up to c->highest_ino. There may be a lot of lookups which fail, if the inode# space is used sparsely. And the inode# space is *often* used sparsely, if a file system contains a lot of stuff that was put there in the original image, followed by lots of creation and deletion of new files. Instead of processing them numerically with a lookup each time, just walk the hash buckets instead.

jffs2: Erase pending blocks in GC pass, avoid invalid -EIO return jffs2_garbage_collect_pass() would previously return -EAGAIN if it couldn't find anything to garbage collect from, and there were blocks on the erase_pending_list. If the blocks were actually in the process of being erased, though, then they wouldn't be on that list. Check for nr_erasing_blocks being non-zero instead. Fix jffs2_reserve_space() to wait for the in-progress erases to complete, when jffs2_garbage_collect_pass() returns -EAGAIN. And fix jffs2_erase_succeeded() to actually wake up the erase_wait wq that jffs2_reserve_space() is now using. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

[JFFS2] Fix jffs2_reserve_space() when all blocks are pending erasure. When _all_ the blocks were on the erase_pending_list, we could't find a block to GC from but there was no _actually_ free space, and jffs2_reserve_space() would get a little unhappy. Handle this case by returning -EAGAIN from jffs2_garbage_collect_pass(). There are two callers of that function -- jffs2_flush_wbuf_gc(), which will interpret it as an error and flush the writebuffer by other means, and jffs2_reserve_space(), which we modify to respond to -EAGAIN with an immediate call to jffs2_erase_pending_blocks() and another run round the loop.
