Subject: [build bug] recent raid pull request?

Hi Neil,

Linus pulled these bits into yesterday's -git:

  d09571059b89: Merge branch 'for-linus' of git://neil.brown.name/md

but i could not find the lkml mail with the changelog, etc. - so have started a 
new thread here.

These changes introduce a pretty commonly triggering build failure on 32-bit 
kernels:

 drivers/built-in.o: In function `raid45_takeover_raid0':
 raid5.c:(.text+0x575488): undefined reference to `__udivdi3'

Caused by one of these commits:

 28a839785201: md: Update documentation for sync_min and sync_max entries
 fee68723cf6a: md: Cleanup after raid45->raid0 takeover
 3b71bd9337b4: md: Fix dev_sectors on takeover from raid0 to raid4/5
 2b7da309ffe6: md/raid5: remove setting of ->queue_lock

These commits were committed yesterday and have not been in linux-next. If you 
cannot fully test such changes yourself then please wait at least one or two 
days until they have a chance to be tested in linux-next.

I've attached an affected config.

Thanks,

	Ingo
