Contains:
- critical+obvious execve() fix from Al (not an IDE fix but included here
to have IDE changes fully bisectable in the mainline)
- fix the infamous ide_4drives allmodconfig error (Frederik Deweerdt)
- fix checking of PCI BARs 0-3 for standard IDE PCI controllers
(Sergei Shtylyov)
- rework of I/O and MEM resource handling (me)
- preparations for removal of the static array of IDE interfaces (me)
- a lot of coding style fixes (Paolo Ciarrocchi)
- removal of the internal 64k buffer from ide-cd (Borislav Petkov)
- and more (thanks to all people contributing)
PS1 There are still 3-4 IDE updates to go.
PS2 I'm still catching up with the patches/mail from the last week so if
you've sent me something recently please give me few more days for reply
before re-sending.
