| * xfs: fix getbmap vs mmap deadlockChristoph Hellwig2009-04-301-17/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xfs_getbmap (or rather the formatters called by it) copy out the getbmap structures under the ilock, which can deadlock against mmap. This has been reported via bugzilla a while ago (#717) and has recently also shown up via lockdep. So allocate a temporary buffer to format the kernel getbmap structures into and then copy them out after dropping the locks. A little problem with this is that we limit the number of extents we can copy out by the maximum allocation size, but I see no real way around that.

* | Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtcDavid Gibson2009-05-0233-45/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The powerpc kernel always requires an Open Firmware like device tree to supply device information. On systems without OF, this comes from a flattened device tree blob. This blob is usually generated by dtc, a tool which compiles a text description of the device tree into the flattened format used by the kernel. Sometimes, the bootwrapper makes small changes to the pre-compiled device tree blob (e.g. filling in the size of RAM). To do this it uses the libfdt library. Because these are only used on powerpc, the code for both these tools is included under arch/powerpc/boot (these were imported and are periodically updated from the upstream dtc tree). However, the microblaze architecture, currently being prepared for merging to mainline also uses dtc to produce device tree blobs. A few other archs have also mentioned some interest in using dtc. Therefore, this patch moves dtc and libfdt from arch/powerpc into scripts, where it can be used by any architecture. The vast bulk of this patch is a literal move, the rest is adjusting the various Makefiles to use dtc and libfdt correctly from their new locations.
