Summary
parisc: BTLB: Fix crash when setting up BTLB at CPU bringup
Details

In the Linux kernel, the following vulnerability has been resolved:

parisc: BTLB: Fix crash when setting up BTLB at CPU bringup

When using hotplug and bringing up a 32-bit CPU, ask the firmware about the BTLB information to set up the static (block) TLB entries.

For that write access to the static btlbinfo struct is needed, but since it is marked _roafterinit the kernel segfaults with missing write permissions.

Fix the crash by dropping the _roafter_init annotation.
