From: Arnd Bergmann <[email protected]>
These patches fix miscellaneous problems when working
with make randconfig. They were discovered on kernel
3.1-rc4 and have been reformatted for 3.4.
Arnd Bergmann (7):
scsi: mark SCSI_SRP as experimental
scsi/nsp32: don't pass large values into udelay
drivers/scsi: use correct __devexit_p annotation
scsi/advansys: do not build on ARM
scsi/atp870u: use mdelay instead of large udelay
scsi/megaraid: fix sparse warnings
drivers/scsi: some ISA drivers need ISA_DMA_API

1.7.5.4
From: Arnd Bergmann <[email protected]>
The two options are separate, and some platforms (e.g. arm pxa)
have ISA slots but no ISA dma controller, so they cannot build
drivers using the enable_dma etc functions.

From: Arnd Bergmann <[email protected]>
Some architectures like ARM cannot handle large numbers as
arguments to udelay, so the drivers should use mdelay when
delaying for multiple miliseconds.

Do not include mega_common.h in the megaraid_sas driver. It has
nothing to do with this driver. It is for the older Parallel SCSI
megaraid drivers.

Ok. I think I first tried moving all declarations into mega_common.h
and then decided otherwise but forgot to remove that #include statement
again. Thanks for taking a look!
