Hi all,

After merging the irqchip tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

arch/powerpc/platforms/pseries/vas.c: In function 'allocate_setup_window':
arch/powerpc/platforms/pseries/vas.c:219:22: error: implicit declaration of function 'irq_create_mapping' [-Werror=implicit-function-declaration]
219 | txwin->fault_virq = irq_create_mapping(NULL, txwin->fault_irq);
| ^~~~~~~~~~~~~~~~~~
arch/powerpc/platforms/pseries/vas.c:248:2: error: implicit declaration of function 'irq_dispose_mapping' [-Werror=implicit-function-declaration]
248 | irq_dispose_mapping(txwin->fault_virq);
| ^~~~~~~~~~~~~~~~~~~

Caused by commit

582f5aa1dbb3 ("powerpc: Drop dependency between asm/irq.h and linux/irqdomain.h")

interacting with commit

6d0aaf5e0de0 ("powerpc/pseries/vas: Setup IRQ and fault handling")

from the powerpc tree

I have applied the following merge fix patch for today. This could, of
course, be applied directly to the powerpc tree ...
