Pull irqchip fixes from Marc Zyngier:

- More compatible strings for the Ingenic irqchip (introducing the
JZ4760B SoC)
- Select GENERIC_IRQ_MULTI_HANDLER on the ARM ep93xx platform
- Drop all GENERIC_IRQ_MULTI_HANDLER selections from the irqchip
Kconfig, now relying on the architecture to get it right
- Drop the debugfs_file field from struct irq_domain, now that
debugfs can track things on its own

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull KVM updates from Paolo Bonzini:
"x86:

- Support for userspace to emulate Xen hypercalls

- Raise the maximum number of user memslots

- Scalability improvements for the new MMU.

Instead of the complex "fast page fault" logic that is used in
mmu.c, tdp_mmu.c uses an rwlock so that page faults are concurrent,
but the code that can run against page faults is limited. Right now
only page faults take the lock for reading; in the future this will
be extended to some cases of page table destruction. I hope to
switch the default MMU around 5.12-rc3 (some testing was delayed
due to Chinese New Year).

- Cleanups for MAXPHYADDR checks

- Use static calls for vendor-specific callbacks

- On AMD, use VMLOAD/VMSAVE to save and restore host state

- Stop using deprecated jump label APIs

- Workaround for AMD erratum that made nested virtualization
unreliable

- Support for LBR emulation in the guest

- Support for communicating bus lock vmexits to userspace

- Add support for SEV attestation command

- Miscellaneous cleanups

PPC:

- Support for second data watchpoint on POWER10

- Remove some complex workarounds for buggy early versions of POWER9

- Guest entry/exit fixes

ARM64:

- Make the nVHE EL2 object relocatable

- Cleanups for concurrent translation faults hitting the same page

- Support for the standard TRNG hypervisor call

- A bunch of small PMU/Debug fixes

- Simplification of the early init hypercall handling

Non-KVM changes (with acks):

- Detection of contended rwlocks (implemented only for qrwlocks,
because KVM only needs it for x86)

- Allow __DISABLE_EXPORTS from assembly code

- Provide a saner follow_pfn replacements for modules"

KVM: arm64: Generate hyp relocation data

Add a post-processing step to compilation of KVM nVHE hyp code which
calls a custom host tool (gen-hyprel) on the partially linked object
file (hyp sections' names prefixed).

The tool lists all R_AARCH64_ABS64 data relocations targeting hyp
sections and generates an assembly file that will form a new section
.hyp.reloc in the kernel binary. The new section contains an array of
32-bit offsets to the positions targeted by these relocations.

Since these addresses of those positions will not be determined until
linking of `vmlinux`, each 32-bit entry carries a R_AARCH64_PREL32
relocation with addend <section_base_sym> + <r_offset>. The linker of
`vmlinux` will therefore fill the slot accordingly.

This relocation data will be used at runtime to convert the kernel VAs
at those positions to hyp VAs.
