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
btlb_info struct is needed, but since it is marked __ro_after_init the
kernel segfaults with missing write permissions. Fix the crash by dropping
the __ro_after_init annotation.
