md currently uses csum_partial to calculate checksums for superblocks. However this function is not consistent across all architectures. Some (i386) to a 32bit csum. Some (alpha) do a 16 bit csum. This makes it hard for userspace to keep up. So we provide a generic routine (that does exactly what the i386 csum_partial does) and: - When setting the csum, use csum_partial so that old kernels will still recognise the superblock - When checking the csum, allow either csum_partial or the new generic code to provide the right csum. This allows user-space to just use the common code and always work. Also modify the csum for version-1 superblock (which currently aren't being used) to always user a predictable checksum algorithm. Thanks to Mike Tran <mhtran@us.ibm.com> for noticing this.

In porting the sn_console driver to the serial core, we lost sysrq support. This patch fixes it and removes a few unncessary #ifdefs. Can you please send it on to Linus asap? sysrq is a *really* nice thing to have.

Dave Hansen recently did some bootmem and paging init cleanups, but I missed this little bit when I tested his original patches. We need to initialize pgdat->node_mem_map correctly since a) we're using vmem_map, and b) the core won't do it for us since we have a valid node_start_pfn I believe.

Rusty decided to preprocess a *.lds.S file in parallele with the new *.lds infrastructure being added to kbuild. Fix that up. Also added the file to targets so we do not see recompile each time the kernel is build. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

Gadgetfs updates: - Resolve a problem that came from a change in the API to AIO: kiocb->private type and size changed, but the name remained the same ... so GCC wouldn't report pending memory-corruption. - Probe the controller at runtime, eliminatingting config-specific defines which need to be updated for each new controller. Rip out the old #defines. - Use newish APIs to let VBUS current be used to recharge batteries (or whatever). - Use no_llseek() ... endpoints are pure data streams.

This patch gets rid of the tcp_default_win_scale sysctl and instead computes the optimum maximum window scale. It just means one less thing to have to tune. I also moved the code out of the inline because it gets called three places and isn't in the critical path. As a side effect, it will cause a smaller window scale for many people since the default tcp_rmem fits in a win_scale of 2. This is allows for finer grain windows (good), but may mask some of the problems with bad implementations we have already seen (bad).

The previous workaround didn't enable the BTIC bit on CPUs where it is broken. However, it seems some firmwares will unconditionally set it, so this new patch will actually _clear_ it on CPUs where it is broken.

That was a nasty one - missing include of config.h in a file that has non-trivial ifdefs. With some configs it ended up with very odd conflicts (we get included early, take the wrong branch of ifdef, then get another file included, it pulls in config.h and picks the right branch of its ifdef; surprise, surprise, they conflict).
