Merge tag 'v7.2-rc1' into drm-rust-next

Merge v7.2-rc1 into drm-rust-next to start the next cycle.

Devres now requires T: 'static, which conflicts with shmem::Object using
Devres<SGTableMap<T, C>> without that bound. Resolve by adding 'static
as a supertrait to DriverObject and DeviceContext, which does not
restrict any current use cases since DriverObject is always implemented
on owned, refcounted types and DeviceContext is a sealed marker trait
with only unit-type implementors.

If DriverObject (or DeviceContext) ever becomes lifetime-parameterized
(e.g. via a GAT for TTM backed objects), the 'static supertrait can be
relaxed at that point.

powerpc64/bpf: Add powerpc64 JIT support for timed may_goto

powerpc64/bpf: Add powerpc64 JIT support for timed may_goto

When verifier sees a timed may_goto instruction, it emits a call to
arch_bpf_timed_may_goto() with a stack offset in BPF_REG_AX
(powerpc64 R12) and expects the refreshed count value to be returned
in the same register. The verifier doesn't save or restore any registers
before emitting this call.

arch_bpf_timed_may_goto() should act as a trampoline to call
bpf_check_timed_may_goto() with powerpc64 ELF ABI calling convention.

To support this custom calling convention, implement
arch_bpf_timed_may_goto() in assembly and make sure BPF caller saved
registers are preserved, then call bpf_check_timed_may_goto with
the powerpc64 ABI calling convention where first argument and return
value both are in R3. Finally, move the result back into BPF_REG_AX(R12)
before returning.

Also, introduce bpf_jit_emit_func_call() that computes the offset from
kernel_toc_addr(), validates that the target and emits the ADDIS/ADDI
sequence to load the function address before performing the indirect
branch via MTCTR/BCTRL. The existing code in bpf_jit_emit_func_call_rel()
is refactored to use this function.

powerpc/bpf: Implement extended BPF on PPC32

Implement Extended Berkeley Packet Filter on Powerpc 32

Test result with test_bpf module:

test_bpf: Summary: 378 PASSED, 0 FAILED, [354/366 JIT'ed]

Registers mapping:

[BPF_REG_0] = r11-r12
/* function arguments */
[BPF_REG_1] = r3-r4
[BPF_REG_2] = r5-r6
[BPF_REG_3] = r7-r8
[BPF_REG_4] = r9-r10
[BPF_REG_5] = r21-r22 (Args 9 and 10 come in via the stack)
/* non volatile registers */
[BPF_REG_6] = r23-r24
[BPF_REG_7] = r25-r26
[BPF_REG_8] = r27-r28
[BPF_REG_9] = r29-r30
/* frame pointer aka BPF_REG_10 */
[BPF_REG_FP] = r17-r18
/* eBPF jit internal registers */
[BPF_REG_AX] = r19-r20
[TMP_REG] = r31

As PPC32 doesn't have a redzone in the stack, a stack frame must always
be set in order to host at least the tail count counter.

The stack frame remains for tail calls, it is set by the first callee
and freed by the last callee.

r0 is used as temporary register as much as possible. It is referenced
directly in the code in order to avoid misusing it, because some
instructions interpret it as value 0 instead of register r0
(ex: addi, addis, stw, lwz, ...)

The following operations are not implemented:

case BPF_ALU64 | BPF_DIV | BPF_X: /* dst /= src */
case BPF_ALU64 | BPF_MOD | BPF_X: /* dst %= src */
case BPF_STX | BPF_XADD | BPF_DW: /* *(u64 *)(dst + off) += src */

The following operations are only implemented for power of two constants:

case BPF_ALU64 | BPF_MOD | BPF_K: /* dst %= imm */
case BPF_ALU64 | BPF_DIV | BPF_K: /* dst /= imm */
