 A set of fixes for the interrupt subsystem:
 
   - Core code:
 
     A regression fix for the Open Firmware interrupt mapping code where a
     interrupt controller property in a node caused a map property in the
     same node to be ignored.
 
   - Interrupt chip drivers:
 
     - Workaround a limitation in SiFive PLIC interrupt chip which silently
       ignores an EOI when the interrupt line is masked.
 
     - Provide the missing mask/unmask implementation for the CSKY MP
       interrupt controller.
 
   - PCI/MSI:
 
     - Prevent a use after free when PCI/MSI interrupts are released by
       destroying the sysfs entries before freeing the memory which is
       accessed in the sysfs show() function.
 
     - Implement a mask quirk for the Nvidia ION AHCI chip which does not
       advertise masking capability despite implementing it. Even worse the
       chip comes out of reset with all MSI entries masked, which due to the
       missing masking capability never get unmasked.
 
     - Move the check which prevents accessing the MSI[X] masking for XEN
       back into the low level accessors. The recent consolidation missed
       that these accessors can be invoked from places which do not have
       that check which broke XEN. Move them back to he original place
       instead of sprinkling tons of these checks all over the code.
