2007-10-23ppc: fix AT_VECTOR_SIZE on arch/ppcGrant Likely1-0/+1
Commit 4f9a58d75bfe82ab2b8ba5b8506dfb190a267834 ("increase AT_VECTOR_SIZE to terminate saved_auxv properly") changes the size of AT_VECTOR_SIZE from hard coded '44' to a calculation based on the value of AT_VECTOR_SIZE_ARCH and AT_VECTOR_SIZE_BASE. The change works for arch/powerpc, but it breaks arch/ppc because the needed AT_VECTOR_SIZE_ARCH is not present in include/asm-ppc/system.h and a default value of 0 is used instead. This results in AT_VECTOR_SIZE being too small and it causes a kernel crash on loading init.

2007-10-23[MIPS] time: SMP-proofing of Sibyte clockevent/clocksource code.Ralf Baechle7-167/+158
The BCM148 has 4 cores but there are also just 4 generic timers available so use the ZBbus cycle counter instead of it. In addition the ZBbus counter also offers a much higher resolution and 64-bit counting so I'm considering a later complete conversion to it once I figure out if all members of the Sibyte SOC family support it - the docs seem to agree but the headers files seem to disagree ...

2007-10-22Change table chaining layoutJens Axboe25-49/+79
Change the page member of the scatterlist structure to be an unsigned long, and encode more stuff in the lower bits: - Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located at sg + 1. - Bit 0 set: this is a chain entry, the next real entry is at ->page_link with the two low bits masked off. - Bit 1 set: this is the final entry in the sg entry. sg_next() will return NULL when passed such an entry. It's thus important that sg table users use the proper accessors to get and set the page member. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-10-22exportfs: add new methodsChristoph Hellwig3-6/+248
Add the guts for the new filesystem API to exportfs. There's now a fh_to_dentry method that returns a dentry for the object looked for given a filehandle fragment, and a fh_to_parent operation that returns the dentry for the encoded parent directory in case the file handle contains it. There are default implementations for these methods that only take a callback for an nfs-enhanced iget variant and implement the rest of the semantics.

2007-10-22exportfs: add fid typeChristoph Hellwig3-57/+90
This patchset is a medium scale rewrite of the export operations interface. The goal is to make the interface less complex, and easier to understand from the filesystem side, aswell as preparing generic support for exporting of 64bit inode numbers. This touches all nfs exporting filesystems, and I've done testing on all of the filesystems I have here locally (xfs, ext2, ext3, reiserfs, jfs) This patch: Add a structured fid type so that we don't have to pass an array of u32 values around everywhere. It's a union of possible layouts. As a start there's only the u32 array and the traditional 32bit inode format, but there will be more in one of my next patchset when I start to document the various filehandle formats we have in lowlevel filesystems better. Also add an enum that gives the various filehandle types human- readable names. Note: Some people might think the struct containing an anonymous union is ugly, but I didn't want to pass around a raw union type.
