[PATCH 0/4] avoid disabling interrupts where it is not required

[Sebastian Andrzej Siewior]

This series avoids/limits disabling of interrupts in drivers/ide.
This is from the -RT queue where it was reported initially (ata was not
widespread back then) and it hurts -RT.

While looking at alim15x3, there are some drivers which exist in both
worlds (alim15x3 included was far as I can tell). Is there a reason why
we still keep two drivers around for the same hardware? I know on mips
bigsur and swarm select IDE in their defconfig. I fixed (ages ago) ide
for swarm while I was using ata myself. So *I* think this just a relict.
If Ralf's bigsur is still alive, it is using SATA and not the onboard
IDE.
