This is arm64 version of commit fec56f5890d9 ("bpf: Introduce BPF
trampoline"). A bpf trampoline converts native calling convention to bpf
calling convention and is used to implement various bpf features, such
as fentry, fexit, fmod_ret and struct_ops.
This patch does essentially the same thing that bpf trampoline does on x86.

Implement bpf_arch_text_poke() for arm64, so bpf prog or bpf trampoline
can be patched with it.
When the target address is NULL, the original instruction is patched to
a NOP.
When the target address and the source address are within the branch
range, the original instruction is patched to a bl instruction to the
target address directly.
To support attaching bpf trampoline to both regular kernel function and
bpf prog, we follow the ftrace patchsite way for bpf prog. That is, two
instructions are inserted at the beginning of bpf prog, the first one
saves the return address to x9, and the second is a nop which will be
patched to a bl instruction when a bpf trampoline is attached.
However, when a bpf trampoline is attached to bpf prog, the distance
between target address and source address may exceed 128MB, the maximum
branch range, because bpf trampoline and bpf prog are allocated
separately with vmalloc. So long jump should be handled.
When a bpf prog is constructed, a plt pointing to empty trampoline
dummy_tramp is placed at the end:
bpf_prog:
mov x9, lr
nop // patchsite
...
ret
plt:
ldr x10, target
br x10
target:
.quad dummy_tramp // plt target
This is also the state when no trampoline is attached.
When a short-jump bpf trampoline is attached, the patchsite is patched to
a bl instruction to the trampoline directly:
bpf_prog:
mov x9, lr
bl <short-jump bpf trampoline address> // patchsite
...
ret
plt:
ldr x10, target
br x10
target:
.quad dummy_tramp // plt target
When a long-jump bpf trampoline is attached, the plt target is filled with
the trampoline address and the patchsite is patched to a bl instruction to
the plt:
bpf_prog:
mov x9, lr
bl plt // patchsite
...
ret
plt:
ldr x10, target
br x10
target:
.quad <long-jump bpf trampoline address>
dummy_tramp is used to prevent another CPU from jumping to an unknown
location during the patching process, making the patching process easier.
The patching process is as follows:
1. when neither the old address or the new address is a long jump, the
patchsite is replaced with a bl to the new address, or nop if the new
address is NULL;
2. when the old address is not long jump but the new one is, the
branch target address is written to plt first, then the patchsite
is replaced with a bl instruction to the plt;
3. when the old address is long jump but the new one is not, the address
of dummy_tramp is written to plt first, then the patchsite is replaced
with a bl to the new address, or a nop if the new address is NULL;
4. when both the old address and the new address are long jump, the
new address is written to plt and the patchsite is not changed.

Add LDR (literal) instruction to load data from address relative to PC.
This instruction will be used to implement long jump from bpf prog to
bpf trampoline in the follow-up patch.
The instruction encoding:
3 2 2 2 0 0
0 7 6 4 5 0
+-----+-------+---+-----+-------------------------------------+--------+
| 0 x | 0 1 1 | 0 | 0 0 | imm19 | Rt |
+-----+-------+---+-----+-------------------------------------+--------+
for 32-bit, variant x == 0; for 64-bit, x == 1.
branch_imm_common() is used to check the distance between pc and target
address, since it's reused by this patch and LDR (literal) is not a branch
instruction, rename it to label_imm_common().

Before generating bpf trampoline, x86 calls is_valid_bpf_tramp_flags()
to check the input flags. This check is architecture independent.
So, to be consistent with x86, arm64 should also do this check
before generating bpf trampoline.
However, the BPF_TRAMP_F_XXX flags are not used by user code and the
flags argument is almost constant at compile time, so this run time
check is a bit redundant.
Remove is_valid_bpf_tramp_flags() and add some comments to the usage of
BPF_TRAMP_F_XXX flags, as suggested by Alexei.

Currently, the only way x86 can get an early boot RNG seed is via EFI,
which is generally always used now for physical machines, but is very
rarely used in VMs, especially VMs that are optimized for starting
"instantaneously", such as Firecracker's MicroVM. For tiny fast booting
VMs, EFI is not something you generally need or want.
Rather, the image loader or firmware should be able to pass a single
random seed, exactly as device tree platforms do with the "rng-seed"
property. Additionally, this is something that bootloaders can append,
with their own seed file management, which is something every other
major OS ecosystem has that Linux does not (yet).
Add SETUP_RNG_SEED, similar to the other eight setup_data entries that
are parsed at boot. It also takes care to zero out the seed immediately
after using, in order to retain forward secrecy. This all takes about 7
trivial lines of code.
Then, on kexec_file_load(), a new fresh seed is generated and passed to
the next kernel, just as is done on device tree architectures when
using kexec. And, importantly, I've tested that QEMU is able to properly
pass SETUP_RNG_SEED as well, making this work for every step of the way.
This code too is pretty straight forward.
Together these measures ensure that VMs and nested kexec()'d kernels
always receive a proper boot time RNG seed at the earliest possible
stage from their parents:
- Host [already has strongly initialized RNG]
- QEMU [passes fresh seed in SETUP_RNG_SEED field]
- Linux [uses parent's seed and gathers entropy of its own]
- kexec [passes this in SETUP_RNG_SEED field]
- Linux [uses parent's seed and gathers entropy of its own]
- kexec [passes this in SETUP_RNG_SEED field]
- Linux [uses parent's seed and gathers entropy of its own]
- kexec [passes this in SETUP_RNG_SEED field]
- ...
I've verified in several scenarios that this works quite well from a
host kernel to QEMU and down inwards, mixing and matching loaders, with
every layer providing a seed to the next.

The guest must have access to certain facilities in order to allow
interpretive execution of zPCI instructions and adapter event
notifications. However, there are some cases where a guest might
disable interpretation -- provide a mechanism via which we can defer
enabling the associated zPCI interpretation facilities until the guest
indicates it wishes to use them.

When doing device passthrough where interrupts are being forwarded from
host to guest, we wish to use a pinned section of guest memory as the
vector (the same memory used by the guest as the vector). To accomplish
this, add a new parameter for airq_iv_create which allows passing an
existing vector to be used instead of allocating a new one. The caller
is responsible for ensuring the vector is pinned in memory as well as for
unpinning the memory when the vector is no longer needed.
A subsequent patch will use this new parameter for zPCI interpretation.

Chimera Linux notes that CONFIG_CC_HAS_SANE_STACKPROTECTOR cannot be
enabled when cross compiling an x86_64 kernel with clang, even though it
does work when natively compiling.
When building on aarch64:
$ make -sj"$(nproc)" ARCH=x86_64 LLVM=1 defconfig
$ grep STACKPROTECTOR .config
When building on x86_64:
$ make -sj"$(nproc)" ARCH=x86_64 LLVM=1 defconfig
$ grep STACKPROTECTOR .config
CONFIG_CC_HAS_SANE_STACKPROTECTOR=y
CONFIG_HAVE_STACKPROTECTOR=y
CONFIG_STACKPROTECTOR=y
CONFIG_STACKPROTECTOR_STRONG=y
When clang is invoked without a '--target' flag, code is generated for
the default target, which is usually the host (it is configurable via
cmake). As a result, the has-stack-protector scripts will generate code
for the default target but check for x86 specific segment registers,
which cannot succeed if the default target is not x86.
$(CLANG_FLAGS) contains an explicit '--target' flag so pass that
variable along to the has-stack-protector scripts so that the stack
protector can be enabled when cross compiling with clang. The 32-bit
stack protector cannot currently be enabled with clang, as it does not
support '-mstack-protector-guard-symbol', so this results in no
functional change for ARCH=i386 when cross compiling.

The kvm_riscv_check_vcpu_requests() is called with SRCU read lock held
and for KVM_REQ_SLEEP request it will block the VCPU without releasing
SRCU read lock. This causes KVM ioctls (such as KVM_IOEVENTFD) from
other VCPUs of the same Guest/VM to hang/deadlock if there is any
synchronize_srcu() or synchronize_srcu_expedited() in the path.
To fix the above in kvm_riscv_check_vcpu_requests(), we should do SRCU
read unlock before blocking the VCPU and do SRCU read lock after VCPU
wakeup.

Pull x86 fixes from Borislav Petkov:
- Prepare for and clear .brk early in order to address XenPV guests
failures where the hypervisor verifies page tables and uninitialized
data in that range leads to bogus failures in those checks
- Add any potential setup_data entries supplied at boot to the identity
pagetable mappings to prevent kexec kernel boot failures. Usually,
this is not a problem for the normal kernel as those mappings are
part of the initially mapped 2M pages but if kexec gets to allocate
the second kernel somewhere else, those setup_data entries need to be
mapped there too.
- Fix objtool not to discard text references from the __tracepoints
section so that ENDBR validation still works
- Correct the setup_data types limit as it is user-visible, before 5.19
releases
