2006-10-03x86: Fix booting with "no387 nofxsr"Linus Torvalds
Jesper Juhl reported that testing the software math-emulation by forcing "no387" doesn't work on modern CPU's. The reason was two-fold: - you also need to pass in "nofxsr" to make sure that we not only don't touch the old i387 legacy hardware, it also needs to disable the modern XMM/FXSR sequences - "nofxsr" didn't actually clear the capability bits immediately, leaving the early boot sequence still using FXSR until we got to the identify_cpu() stage. This fixes the "nofxsr" flag to take effect immediately on the boot CPU.

2006-10-03[PATCH] pr_debug: check pr_debug() argumentsZach Brown
check pr_debug() arguments When DEBUG isn't defined pr_debug() is defined away as an empty macro. By throwing away the arguments we allow completely incorrect code to build. Instead let's make it an empty inline which checks arguments and mark it so gcc can check the format specification. This results in a seemingly insignificant code size increase.

2006-10-03[PATCH] md: remove MAX_MD_DEVS which is an arbitrary limitNeilBrown
Once upon a time we needed to fixed limit to the number of md devices, probably because we preallocated some array. This need no longer exists, but we still have an arbitrary limit. So remove MAX_MD_DEVS and allow as many devices as we can fit into the 'minor' part of a device number. Also remove some useless noise at init time (which reports MAX_MD_DEVS) and remove MD_THREAD_NAME_MAX which hasn't been used for a while.

2006-10-03[PATCH] md: make messages about resync/recovery etc more specificNeilBrown
It is possible to request a 'check' of an md/raid array where the whole array is read and consistancies are reported. This uses the same mechanisms as 'resync' and so reports in the kernel logs that a resync is being started. This understandably confuses/worries people. Also the text in /proc/mdstat suggests a 'resync' is happen when it is just a check. This patch changes those messages to be more specific about what is happening.

raid1, raid10 and multipath don't report their 'congested' status through bdi_*_congested, but should. This patch adds the appropriate functions which just check the 'congested' status of all active members (with appropriate locking). raid1 read_balance should be modified to prefer devices where bdi_read_congested returns false. Then we could use the '&' branch rather than the '|' branch. However that should would need some benchmarking first to make sure it is actually a good idea.

2006-10-03[PATCH] md: Improve locking around error handlingNeilBrown

2006-10-03[PATCH] md: new sysfs interface for setting bits in the write-intent-bitmapPaul Clements
Add a new sysfs interface that allows the bitmap of an array to be dirtied. The interface is write-only, and is used as follows: echo "1000" > /sys/block/md2/md/bitmap (dirty the bit for chunk 1000 [offset 0] in the in-memory and on-disk bitmaps of array md2) echo "1000-2000" > /sys/block/md1/md/bitmap (dirty the bits for chunks 1000-2000 in md1's bitmap) This is useful, for example, in cluster environments where you may need to combine two disjoint bitmaps into one (following a server failure, after a secondary server has taken over the array). By combining the bitmaps on the two servers, a full resync can be avoided (This was discussed on the list back on March 18, 2005, "[PATCH 1/2] md bitmap bug fixes" thread).
