powerpc updates for 6.11

Browse Source 
- Remove support for 40x CPUs & platforms.
 
  - Add support to the 64-bit BPF JIT for cpu v4 instructions.
 
  - Fix PCI hotplug driver crash on powernv.
 
  - Fix doorbell emulation for KVM on PAPR guests (nestedv2).
 
  - Fix KVM nested guest handling of some less used SPRs.
 
  - Online NUMA nodes with no CPU/memory if they have a PCI device attached.
 
  - Reduce memory overhead of enabling kfence on 64-bit Radix MMU kernels.
 
  - Reimplement the iommu table_group_ops for pseries for VFIO SPAPR TCE.

/*
* At present, all PowerPC 400-class processors share a similar TLB
* architecture. The instruction and data sides share a unified,
* 64-entry, fully-associative TLB which is maintained totally under
* software control. In addition, the instruction side has a
* hardware-managed, 4-entry, fully-associative TLB which serves as a
* first level to the shared TLB. These two TLBs are known as the UTLB
* and ITLB, respectively (see "mmu.h" for definitions).
*
* There are several potential gotchas here. The 40x hardware TLBLO
* field looks like this:
*
* 0 1 2 3 4 ... 18 19 20 21 22 23 24 25 26 27 28 29 30 31
* RPN..................... 0 0 EX WR ZSEL....... W I M G
*
* Where possible we make the Linux PTE bits match up with this
*
* - bits 20 and 21 must be cleared, because we use 4k pages (40x can
* support down to 1k pages), this is done in the TLBMiss exception
* handler.
* - We use only zones 0 (for kernel pages) and 1 (for user pages)
* of the 16 available. Bit 24-26 of the TLB are cleared in the TLB
* miss handler. Bit 27 is PAGE_USER, thus selecting the correct
* zone.
* - PRESENT *must* be in the bottom two bits because swap PTEs
* use the top 30 bits. Because 40x doesn't support SMP anyway, M is
* irrelevant so we borrow it for PAGE_PRESENT. Bit 30
* is cleared in the TLB miss handler before the TLB entry is loaded.
* - All other bits of the PTE are loaded into TLBLO without
* modification, leaving us only the bits 20, 21, 24, 25, 26, 30 for
* software PTE bits. We actually use bits 21, 24, 25, and
* 30 respectively for the software bits: ACCESSED, DIRTY, RW, and
* PRESENT.
