When "kernelcore" boot option is specified, kernel can't boot up on ia64

I guess it ends up going through the scheduler, which does use it.

I think a lot of people are tired of this argument, but I am glad you speak

the raw linecount appears to be the following:
Check to see if an ATAPI device supports Asynchronous Notification.
If so, enable it.
changes from last version:
* fix typo in ata_id_has_AN and make word 76 test more clear
* If we fail to set the AN feature, just print a warning and continue

Hi Pierre,
Find in this series the pending patches from Linux-OMAP to mainline for
drivers/mmc/omap.c
The patches series was applied against Linus' tree 2.6.21-rc7-git6.
Anyway, it was tested on OMAP H2 (using omap_h2_1610_defconfig available
on linus' tree).
BR,
Carlos.

The following patches should allow selection of conservative, powersave, and
ondemand in the kernel configuration.
