The INTID of EL2 non-secure physical timer is 26. In linux, the IRQ
number has a fixed 16 offset for PPIs. Therefore, the linux IRQ number
of EL2 non-secure physical timer should be 10 (26 - 16).

The EL2 non-secure physical timer is utilized during kernel bootup in
EL2 mode with KVM enabled. This patch has been verified on the QCS8300
platform with KVM enabled. Given that the dependency patch has already
been reviewed, I am uncertain whether it is preferable to submit this
fix as a new patch or to combine it with the dependency patch. I would
appreciate your suggestions on this patch.

This was not merged. Do not post fixes to things which are still patches
on mailing list.

Best regards,
