This reverts commit ef86f3a72adb8a7931f67335560740a7ad696d1d.
See the discussion in the thread *aacraid: Regression in 4.14.56
with *genirq/affinity: assign vectors to all possible CPUs** on
the linux-scsi list.
Reverting the commit, the aacraid driver loads

This seems rather odd. If add all you'd revert the patch adding the
PCI_IRQ_AFFINITY to aacraid, not core infrastructure.

Hello everyone,
I'm looking into adding LED trigger support for UFS device activity. This
essentially means a dedicated LED will blink upon the UFS device activity
like we have for ATA, MTD, NAND devices.
Currently, I'm not sure about the places where we have to insert this trigger.
My only choic

Add BUS_ATTR_WO macro to make it easier to add attributes without
auditing the mode settings. Also, use the newly added macro where
appropriate.

Hynix ufs has deviations on hi36xx platform which will result in
ufs bursts transfer failures.
To fix the problem, the Hynix device must set the register
VS_DebugSaveConfigTime to 0x10, which will set time reference
for SaveConfigTime is 250 ns. The time reference for SaveConfigTime

Christoph,
I was able to bisect this to your patch "scsi: reduce use of block
bounce buffers". I am getting the error on a 32-bit Dell PowerEdge
6650. It has the aic7xxx integrated onto the motherboard.
Again, here is the error:

Done.
