What's happening with the cpuidle code?

A look at the 'cpuidle' branch of git-acpi shows a commit e40cede7d63a029e92712a3fe02faee60cc38fb4, "cpuidle: first round of documentation updates" that doesn't show up in that branch online. The entire Documentation/cpuidle directory is missing from the tree when looking at the web pages, and it's missing from git-acpi.patch in 2.6.23-rc4-mm1 (but the patch shows up in the summary information in the patch header.) Where did it go? And how can -mm be used to test things if its patches don't even match their own headers?

A later patch in that series, "cpuidle: re-write", reverted the documentation from the intermediate patch that you refer to:

http://git.kernel.org/?p=linux/kernel/git/lenb/linux-acpi-2.6.git;a=commit;h=2305a5920fb8ee6ccec1c62ade05aa8351091d71

The cpuidle branch on git.kernel.org looks okay to me:

http://git.kernel.org/?p=linux/kernel/git/lenb/linux-acpi-2.6.git;a=shortlog;h=cpuidle

the top commit is this one:

CPUIDLE: load ACPI properly when CPUIDLE is disabled

And this top patch is indeed included in the latest acpi test branch, as well as the latest ACPI test patch here:

http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/test/2.6.23/acpi-test-20070126-2.6.23-rc5.diff.gz

Note that there were some merge conflicts when pulling cpuidle into 2.6.23, so you are best off running either the acpi patch above on top of 2.6.23-rc5, or the acpi test branch, or the mm tree so you won't have to merge the cpuidle branch onto your latest kernel again.

cheers,

It never occurred to me that a patch would just remove documentation. Thanks for looking into that...
