+Subject: [PATCH] Fix "irq -a" option on Linux 6.0 and later
+
+Kernel commit f0dd891dd5a1d ("lib/cpumask: move some one-line wrappers
+to header file"), which is contained in Linux 6.0 and later kernels,
+inlined alloc_cpumask_var() function.  As a result, the "irq -a" option
+fails to determine that cpumask_var_t is a pointer, and displays wrong
+CPU affinity for IRQs:
+
+  crash> irq -a
+  IRQ NAME                 AFFINITY
+    1 i8042                3
+    4 ttyS0
+    8 rtc0
+    9 acpi                 3
+   12 i8042                3
+  ...
+
+Use alloc_cpumask_var_node() function symbol instead to fix it.
