Because of the tagged addresses, the __is_lm_address() and
__lm_to_phys() macros grew to some harder to understand bitwise
operations using PAGE_OFFSET. Since these macros only accept untagged
addresses, use a simple subtract operation.

Commit 519ea6f1c8 ("arm64: Fix kernel address detection of
__is_lm_address()") fixed the incorrect validation of addresses below
PAGE_OFFSET. However, it no longer allowed tagged addresses to be passed
to virt_addr_valid().
Fix this by explicitly resetting the pointer tag prior to invoking
__is_lm_address(). This is consistent with the __lm_to_phys() macro.

KVM/arm64 fixes for 5.11, take #3
- Avoid clobbering extra registers on initialisation
These are the current arm-soc bug fixes for linux-5.11. I already merged
a larger set that just came in during the past three days but has not
had much exposure in linux-next, so these are the ones I merged last week.
Most of these are for the NXP i.MX platform (descriptions from their
pull request):
- Fix pcf2127 reset for imx7d-flex-concentrator board.
- Fix i.MX6 suspend with Thumb-2 kernel.
- Fix ethernet-phy address issue on imx6qdl-sr-som board.
- Fix GPIO3 `gpio-ranges` on i.MX8MP.
- Select SOC_BUS for IMX_SCU driver to fix build issue.
- Fix backlight pwm on imx6qdl-kontron-samx6i which is lost from
#pwm-cells conversion.
- Fix duplicated bus node name for i.MX8MN SoC.
- Fix reset register offset on LS1028A SoC.
- Rename MMC node aliases for imx6q-tbs2910 to keep the MMC device
index consistent with previous kernel version.
- Selecting ARM_GIC_V3 on non-CP15 processors to fix one build failure
with i.MX8M SoC driver.
- Fix typos with status property on imx6qdl-kontron-samx6i board.
- Fix duplicated regulator-name on imx6qdl-gw52xx board.
Aside from i.MX, the bugfixes are all over the place:
- Coccinelle found a refcount imbalance on integrator
- defconfig fix for TI K3
- A boot regression fix for ST ux500
- A code preemption fix for the optee driver
- USB DMA regression on Broadcom Stingray
- A bogus boot time warning fix for at91 code

For the proper reboot Odroid-C4 board requires to switch TFLASH_VDD_EN
pin to the high impedance mode, otherwise the board is stuck in the
middle of loading early stages of the bootloader from SD card.
This can be achieved by using the OPEN_DRAIN flag instead of the
ACTIVE_HIGH, what will leave the pin in input mode to achieve high state
(pin has the pull-up) and solve the issue.

Currently, the __is_lm_address() check just masks out the top 12 bits
of the address, but if they are 0, it still yields a true result.
This has as a side effect that virt_addr_valid() returns true even for
invalid virtual addresses (e.g. 0x0).
Fix the detection checking that it's actually a kernel address starting
at PAGE_OFFSET.

internal PHY support on the Amlogic G12A/SM1 Based boards.
We suspect the added signal to reset more than the Ethernet MAC but also
the MDIO/(RG)MII mux used to redirect the MAC signals to the internal PHY.
This reverts commit f3362f0c18 while we find

NanoPi R2S is headless, so rightly does not enable any of the display
interface hardware, which currently provokes an obnoxious error in the
boot log from the fake DRM device failing to find anything to bind to.
It probably isn't *too* hard to obviate the fake device shenanigans
entirely with a bit of driver reshuffling, but for now let's just
disable it here to shut up the spurious error.

As of the "arm64: expose FAR_EL1 tag bits in siginfo" patch, the address
that is passed to report_tag_fault has pointer tags in the format of 0x0X,
while KASAN uses 0xFX format (note the difference in the top 4 bits).
Fix up the pointer tag for kernel pointers in do_tag_check_fault by
setting them to the same value as bit 55. Explicitly use __untagged_addr()
instead of untagged_addr(), as the latter doesn't affect TTBR1 addresses.

The kbuild test robot reports that when building with W=1, GCC will warn
for a couple of missing prototypes in syscall.c:
| arch/arm64/kernel/syscall.c:157:6: warning: no previous prototype for 'do_el0_svc' [-Wmissing-prototypes]
| 157 | void do_el0_svc(struct pt_regs *regs)
| | ^~~~~~~~~~
| arch/arm64/kernel/syscall.c:164:6: warning: no previous prototype for 'do_el0_svc_compat' [-Wmissing-prototypes]
| 164 | void do_el0_svc_compat(struct pt_regs *regs)
| | ^~~~~~~~~~~~~~~~~
While this isn't a functional problem, as a general policy we should
include the prototype for functions wherever possible to catch any
accidental divergence between the prototype and implementation. Here we
can easily include <asm/exception.h>, so let's do so.
While there are a number of warnings elsewhere and some warnings enabled
under W=1 are of questionable benefit, this change helps to make the
code more robust as it evolved and reduces the noise somewhat, so it
seems worthwhile.

A subsequent patch will add additional atomic operations. These new
operations will use the same opcode field as the existing XADD, with
the immediate discriminating different operations.
In preparation, rename the instruction mode BPF_ATOMIC and start
calling the zero immediate BPF_ADD.
This is possible (doesn't break existing valid BPF progs) because the
immediate field is currently reserved MBZ and BPF_ADD is zero.
All uses are removed from the tree but the BPF_XADD definition is
kept around to avoid breaking builds for people including kernel
headers.

The reg_to_encoding() macro is a wrapper over sys_reg() and conveniently
takes a sys_reg_desc or a sys_reg_params argument and returns the 32 bit
register encoding. Use it instead of calling sys_reg() directly.

The KVM/arm64 PSCI relay assumes that SYSTEM_OFF and SYSTEM_RESET should
not return, as dictated by the PSCI spec. However, there is firmware out
there which breaks this assumption, leading to a hyp panic. Make KVM
more robust to broken firmware by allowing these to return.

Now that all PMU registers are gated behind a .visibility callback,
remove the other checks against an absent PMU.
Signed-off-by: Marc Zyngier <maz@kernel.org>
It appears that while we are now able to properly hide PMU
registers from the guest when a PMU isn't available (either
because none has been configured, the host doesn't have
the PMU support compiled in, or that the HW doesn't have
one at all), we are still exposing more than we should to
userspace.
Introduce a visibility callback gating all the PMU registers,
which covers both usrespace and guest.

With UBSAN enabled and building with clang, there are occasionally
warnings like
WARNING: modpost: vmlinux.o(.text+0xc533ec): Section mismatch in reference from the function arch_atomic64_or() to the variable .init.data:numa_nodes_parsed
The function arch_atomic64_or() references
the variable __initdata numa_nodes_parsed.
This is often because arch_atomic64_or lacks a __initdata
annotation or the annotation of numa_nodes_parsed is wrong.
for functions that end up not being inlined as intended but operating
on __initdata variables. Mark these as __always_inline, along with
the corresponding asm-generic wrappers.

S_FRAME_SIZE is the size of the pt_regs structure, no longer the size of
the kernel stack frame, the name is misleading. In keeping with arm32,
rename S_FRAME_SIZE to PT_REGS_SIZE.

This reverts commit 367c820ef0.
lockup_detector_init() makes heavy use of per-cpu variables and must be
called with preemption disabled. Usually, it's handled early during boot
in kernel_init_freeable(), before SMP has been initialised.
Since we do not know whether or not our PMU interrupt can be signalled
as an NMI until considerably later in the boot process, the Arm PMU
driver attempts to re-initialise the lockup detector off the back of a
device_initcall(). Unfortunately, this is called from preemptible
context and results in the following splat:
| BUG: using smp_processor_id() in preemptible [00000000] code: swapper/0/1
| caller is debug_smp_processor_id+0x20/0x2c
| CPU: 2 PID: 1 Comm: swapper/0 Not tainted 5.10.0+ #276

| kernel_init_freeable+0x368/0x380

| ret_from_fork+0x10/0x30
Rather than bodge this with raw_smp_processor_id() or randomly disabling
preemption, simply revert the culprit for now until we figure out how to
do this properly.

All EL0 returns go via ret_to_user(), which masks IRQs and notifies
lockdep and tracing before calling into do_notify_resume(). Therefore,
there's no need for do_notify_resume() to call trace_hardirqs_off(), and
the comment is stale. The call is simply redundant.
In ret_to_user() we call exit_to_user_mode(), which notifies lockdep and
tracing the IRQs will be enabled in userspace, so there's no need for
el0_svc_common() to call trace_hardirqs_on() before returning. Further,
at the start of ret_to_user() we call trace_hardirqs_off(), so not only
is this redundant, but it is immediately undone.
In addition to being redundant, the trace_hardirqs_on() in
el0_svc_common() leaves lockdep inconsistent with the hardware state,
and is liable to cause issues for any C code or instrumentation
between this and the call to trace_hardirqs_off() which undoes it in
ret_to_user().
This patch removes the redundant tracing calls and associated stale
comments.
