0ebeea8ca8 bpf: Restrict bpf_probe_read{, str}() only to archs where they work
Given the legacy bpf_probe_read{,str}() BPF helpers are broken on archs
with overlapping address ranges, we should really take the next step to
disable them from BPF use there.

To generally fix the situation, we've recently added new helper variants
bpf_probe_read_{user,kernel}() and bpf_probe_read_{user,kernel}_str().
For details on them, see 6ae08ae3de ("bpf: Add probe_read_{user, kernel}
and probe_read_{user,kernel}_str helpers").

Given bpf_probe_read{,str}() have been around for ~5 years by now, there
are plenty of users at least on x86 still relying on them today, so we
cannot remove them entirely w/o breaking the BPF tracing ecosystem.

However, their use should be restricted to archs with non-overlapping
address ranges where they are working in their current form. Therefore,
move this behind a CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE and
have x86, arm64, arm select it (other archs supporting it can follow-up
on it as well).

For the remaining archs, they can workaround easily by relying on the
feature probe from bpftool which spills out defines that can be used out
of BPF C code to implement the drop-in replacement for old/new kernels
via: bpftool feature probe macro

92db978f0d net: ethernet: ti: Remove TI_CPTS_MOD workaround
My recent commit b6d49cab44 ("net: Make PTP-specific drivers depend on
PTP_1588_CLOCK") exposes a missing dependency in defconfigs that select
TI_CPTS without selecting PTP_1588_CLOCK, leading to linker errors of the
form:

drivers/net/ethernet/ti/cpsw.o: in function `cpsw_ndo_stop':
cpsw.c:(.text+0x680): undefined reference to `cpts_unregister'
 ...

That's because TI_CPTS_MOD (which is the symbol gating the _compilation_ of
cpts.c) now depends on PTP_1588_CLOCK, and so is not enabled in these
configurations, but TI_CPTS (which is the symbol gating _calls_ to the cpts
functions) _is_ enabled. So we end up compiling calls to functions that
don't exist, resulting in the linker errors.

This patch fixes build errors and restores previous behavior by:
 - ensure PTP_1588_CLOCK=y in TI specific configs and CPTS will be built
 - remove TI_CPTS_MOD and, instead, add dependencies from CPTS in
   TI_CPSW/TI_KEYSTONE_NETCP/TI_CPSW_SWITCHDEV as below:

   config TI_CPSW_SWITCHDEV
   ...
    depends on TI_CPTS || !TI_CPTS

   which will ensure proper dependencies PTP_1588_CLOCK -> TI_CPTS ->
TI_CPSW/TI_KEYSTONE_NETCP/TI_CPSW_SWITCHDEV and build type selection.

Note. For NFS boot + CPTS all of above configs have to be built-in.

e47cb97f15 ARM: dts: r8a7740: Add missing extal2 to CPG node
The Clock Pulse Generator (CPG) device node lacks the extal2 clock.
This may lead to a failure registering the "r" clock, or to a wrong
parent for the "usb24s" clock, depending on MD_CK2 pin configuration and
boot loader CPG_USBCKCR register configuration.

This went unnoticed, as this does not affect the single upstream board
configuration, which relies on the first clock input only.

8101b5a153 ARM: futex: Address build warning
Stephen reported the following build warning on a ARM multi_v7_defconfig
build with GCC 9.2.1:

kernel/futex.c: In function 'do_futex':
kernel/futex.c:1676:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized]
 1676 |   return oldval == cmparg;
      |          ~~~~~~~^~~~~~~~~
kernel/futex.c:1652:6: note: 'oldval' was declared here
 1652 |  int oldval, ret;
      |      ^~~~~~

introduced by commit a08971e948 ("futex: arch_futex_atomic_op_inuser()
calling conventions change").

While that change should not make any difference it confuses GCC which
fails to work out that oldval is not referenced when the return value is
not zero.

GCC fails to properly analyze arch_futex_atomic_op_inuser(). It's not the
early return, the issue is with the assembly macros. GCC fails to detect
that those either set 'ret' to 0 and set oldval or set 'ret' to -EFAULT
which makes oldval uninteresting. The store to the callsite supplied oldval
pointer is conditional on ret == 0.

The straight forward way to solve this is to make the store unconditional.

Aside of addressing the build warning this makes sense anyway because it
removes the conditional from the fastpath. In the error case the stored
value is uninteresting and the extra store does not matter at all.

738b150ece ARM: dts: omap4-droid4: Fix occasional lost wakeirq for uart1
Looks like using the UART CTS pin does not always trigger for a wake-up
when the SoC is idle.

This is probably because the modem first uses gpio_149 to signal the SoC
that data will be sent, and the CTS will only get used later when the
data transfer is starting.

Let's fix the issue by configuring the gpio_149 pad as the wakeirq for
UART. We have gpio_149 managed by the USB PHY for powering up the right
USB mode, and after that, the gpio gets recycled as the modem wake-up
pin. If needeed, the USB PHY can also later on be configured to use
gpio_149 pad as the wakeirq as a shared irq.

30fa60c678 ARM: dts: omap4-droid4: Fix flakey wlan by disabling internal pull for gpio
The wlan on droid4 is flakey on some devices, and experiments have shown this
gets fixed if we disable the internal pull for wlan gpio interrupt line.

The symptoms are that the wlan connection is very slow and almost useless
with lots of wlcore firmware reboot warnings in the dmesg.

In addition to configuring the wlan gpio pulls, let's also configure the rest
of the wlan sd pins. We have not configured those eariler as we're booting
using kexec.

a9a8ba90fa crypto: arch/nhpoly1305 - process in explicit 4k chunks
Rather than chunking via PAGE_SIZE, this commit changes the arch
implementations to chunk in explicit 4k parts, so that calculations on
maximum acceptable latency don't suddenly become invalid on platforms
where PAGE_SIZE isn't 4k, such as arm64.

706024a52c crypto: arch/lib - limit simd usage to 4k chunks
The initial Zinc patchset, after some mailing list discussion, contained
code to ensure that kernel_fpu_enable would not be kept on for more than
a 4k chunk, since it disables preemption. The choice of 4k isn't totally
scientific, but it's not a bad guess either, and it's what's used in
both the x86 poly1305, blake2s, and nhpoly1305 code already (in the form
of PAGE_SIZE, which this commit corrects to be explicitly 4k for the
former two).

Ard did some back of the envelope calculations and found that
at 5 cycles/byte (overestimate) on a 1ghz processor (pretty slow), 4k
means we have a maximum preemption disabling of 20us, which Sebastian
confirmed was probably a good limit.

Unfortunately the chunking appears to have been left out of the final
patchset that added the glue code. So, this commit adds it back in.

b704fc1da9 ARM: dts: r7s9210: Remove bogus clock-names from OSTM nodes
Usually it does not hurt to add "clock-names" properties, even if the
(pre-json-schema) DT bindings do not mention them.

However, the actual clock names for the OS Timer nodes are not fixed,
but contain the indices of the consumer instances.  Hence they cannot
easily be used by a driver, without scanning for all possible indices.

Remove them, as the OSTM DT bindings do not specify clock-names anyway.

62d0fd591d arch: split MODULE_ARCH_VERMAGIC definitions out to <asm/vermagic.h>
As the bug report [1] pointed out, <linux/vermagic.h> must be included
after <linux/module.h>.

I believe we should not impose any include order restriction. We often
sort include directives alphabetically, but it is just coding style
convention. Technically, we can include header files in any order by
making every header self-contained.

Currently, arch-specific MODULE_ARCH_VERMAGIC is defined in
<asm/module.h>, which is not included from <linux/vermagic.h>.

Hence, the straight-forward fix-up would be as follows:

|--- a/include/linux/vermagic.h
|+++ b/include/linux/vermagic.h
|@@ -1,5 +1,6 @@
| /* SPDX-License-Identifier: GPL-2.0 */
| #include <generated/utsrelease.h>
|+#include <linux/module.h>
|
| /* Simply sanity version stamp for modules. */
| #ifdef CONFIG_SMP

This works enough, but for further cleanups, I split MODULE_ARCH_VERMAGIC
definitions into <asm/vermagic.h>.

With this, <linux/module.h> and <linux/vermagic.h> will be orthogonal,
and the location of MODULE_ARCH_VERMAGIC definitions will be consistent.

For arc and ia64, MODULE_PROC_FAMILY is only used for defining
MODULE_ARCH_VERMAGIC. I squashed it.

For hexagon, nds32, and xtensa, I removed <asm/modules.h> entirely
because they contained nothing but MODULE_ARCH_VERMAGIC definition.
Kbuild will automatically generate <asm/modules.h> at build-time,
wrapping <asm-generic/module.h>.

Since commit bcbb63b802 ("ARM: dts: dra7: Separate AM57 dtsi files"),
the m_can node was inherited from dra76x.dtsi but the IP is not
connected on the idk board. Disable the node to reflect this.

3100423dc1 ARM: imx: provide v7_cpu_resume() only on ARM_CPU_SUSPEND=y
512a928aff ("ARM: imx: build v7_cpu_resume() unconditionally")
introduced an unintended linker error for i.MX6 configurations that have
ARM_CPU_SUSPEND=n which can happen if neither CONFIG_PM, CONFIG_CPU_IDLE,
nor ARM_PSCI_FW are selected.

Fix this by having v7_cpu_resume() compiled only when cpu_resume() it
calls is available as well.

The C declaration for the function remains unguarded to avoid future code
inadvertently using a stub and introducing a regression to the bug the
original commit fixed.

d6b0a5b3ab Boot regression fix for N950/N9
We need to tag RNG as disabled for N950/N9 as it blocked by the secure
 mode. We have a similar change done for N900, but I missed adding it
 for N950/N9 with the recent RNG changes.
