Commit Message

Mark Rutland Jan. 25, 2023, 4:38 p.m. UTC 
Subsequent patches will add more GIC-related cpucaps. When we do so, it
would be nice to give them a consistent HAS_GIC_* prefix.

In preparation for doing so, this patch renames the existing
ARM64_HAS_IRQ_PRIO_MASKING cap to ARM64_HAS_GIC_PRIO_MASKING.

The cpucaps file was hand-modified; all other changes were scripted
with:

  find . -type f -name '*.[chS]' -print0 | \
    xargs -0 sed -i 's/ARM64_HAS_IRQ_PRIO_MASKING/ARM64_HAS_GIC_PRIO_MASKING/'

There should be no functional change as a result of this patch.
