Linus Torvalds 8194c28efd powerpc fixes for 5.4 #4
Our recent cleanup of EEH led to an oops on bare metal machines when the cxl
 (CAPI) driver creates virtual devices for an attached FPGA accelerator.
 
 The "secure virtual machine" support we added in v5.4 had a bug if the kernel
 was relocated (moved during boot), in those cases the signature of the kernel
 text wouldn't verify and the Ultravisor would refuse to run the VM.
 
 A recent change to disable interrupts before calling arch_cpu_idle_dead() caused
 a WARN_ON() in our bare metal CPU offline code to always trigger.
 
 The KUAP (SMAP) support we added for 32-bit Book3S had a bug if the address
 range crossed a segment (256MB) boundary which could lead to spurious faults.

   Christophe Leroy, Frederic Barrat, Michael Anderson, Nicholas Piggin, Sam
   Bobroff, Thiago Jung Bauermann.
