dc1d81ee93 hw_breakpoint: fix single-stepping when using bpf_overflow_handler
[ Upstream commit d11a69873d9a7435fe6a48531e165ab80a8b1221 ]

Arm platforms use is_default_overflow_handler() to determine if the
hw_breakpoint code should single-step over the breakpoint trigger or
let the custom handler deal with it.

Since bpf_overflow_handler() currently isn't recognized as a default
handler, attaching a BPF program to a PERF_TYPE_BREAKPOINT event causes
it to keep firing (the instruction triggering the data abort exception
is never skipped). For example:

  # bpftrace -e 'watchpoint:0x10000:4:w { print("hit") }' -c ./test
  Attaching 1 probe...
  hit
  hit
  [...]
  ^C

(./test performs a single 4-byte store to 0x10000)

This patch replaces the check with uses_default_overflow_handler(),
which accounts for the bpf_overflow_handler() case by also testing
if one of the perf_event_output functions gets invoked indirectly,
via orig_default_handler.

a12f15d1f8 bpf: Remove prog->active check for bpf_lsm and bpf_iter
[ Upstream commit 271de525e1d7f564e88a9d212c50998b49a54476 ]

The commit 64696c40d03c ("bpf: Add __bpf_prog_{enter,exit}_struct_ops for struct_ops trampoline")
removed prog->active check for struct_ops prog.  The bpf_lsm
and bpf_iter is also using trampoline.  Like struct_ops, the bpf_lsm
and bpf_iter have fixed hooks for the prog to attach.  The
kernel does not call the same hook in a recursive way.
This patch also removes the prog->active check for
bpf_lsm and bpf_iter.

A later patch has a test to reproduce the recursion issue
for a sleepable bpf_lsm program.

This patch appends the '_recur' naming to the existing
enter and exit functions that track the prog->active counter.
New __bpf_prog_{enter,exit}[_sleepable] function are
added to skip the prog->active tracking. The '_struct_ops'
version is also removed.

It also moves the decision on picking the enter and exit function to
the new bpf_trampoline_{enter,exit}().  It returns the '_recur' ones
for all tracing progs to use.  For bpf_lsm, bpf_iter,
struct_ops (no prog->active tracking after 64696c40d03c), and
bpf_lsm_cgroup (no prog->active tracking after 69fd337a975c7),
it will return the functions that don't track the prog->active.

22ec50d7b5 arm64: dts: renesas: rzg2l: Fix txdv-skew-psec typos
commit db67345716a52abb750ec8f76d6a5675218715f9 upstream.

It looks like txdv-skew-psec is a typo from a copy+paste. txdv-skew-psec
is not present in the PHY bindings nor is it in the driver.

Correct to txen-skew-psec which is clearly what it was meant to be.

Given that the default for txen-skew-psec is 0, and the device tree is
only trying to set it to 0 anyway, there should not be any functional
change from this fix.

8bf567b63c arm64: sdei: abort running SDEI handlers during crash
commit 5cd474e57368f0957c343bb21e309cf82826b1ef upstream.

Interrupts are blocked in SDEI context, per the SDEI spec: "The client
interrupts cannot preempt the event handler." If we crashed in the SDEI
handler-running context (as with ACPI's AGDI) then we need to clean up the
SDEI state before proceeding to the crash kernel so that the crash kernel
can have working interrupts.

Track the active SDEI handler per-cpu so that we can COMPLETE_AND_RESUME
the handler, discarding the interrupted context.

[ Upstream commit 43a684580819e7f35b6cb38236be63c4cba26ef4 ]

The ov5640 driver expects DOVDD, AVDD and DVDD as regulator supply names.

The ov5640 has depended on these names since the driver was committed
upstream in 2017. Similarly apq8016-sbc.dtsi has had completely different
regulator names since its own initial commit in 2020.

Perhaps the regulators were left on in previous 410c bootloaders. In any
case today on 6.5 we won't switch on the ov5640 without correctly naming
the regulators.

 serial-tegra: probe of 70006300.serial failed with error -2

Commit 71de0a054d0e ("arm64: tegra: Drop serial clock-names and
reset-names") is correct because the "reset-names" property is not
needed for 8250 UARTs. However, the "reset-names" is required for the
HSUART and should have been populated as part of commit a63c0cd83720c
("arm64: dts: tegra: smaug: Add Bluetooth node") that enabled the HSUART
for the Pixel C. Fix this by populating the "reset-names" property for
the HSUART on the Pixel C.

d244c92988 arm64: dts: qcom: sm8250: correct dynamic power coefficients
[ Upstream commit 775a5283c25d160b2a1359018c447bc518096547 ]

sm8250 faces the same problem with its Energy Model as sdm845. The energy
cost of LITTLE cores is reported to be higher than medium or big cores

EM computes the energy with formula:

energy = OPP's cost / maximum cpu capacity * utilization

On v6.4-rc6 we have:
max capacity of CPU0 = 284
capacity of CPU0's OPP(1612800 Hz) = 253
cost of CPU0's OPP(1612800 Hz) = 191704

max capacity of CPU4 = 871
capacity of CPU4's OPP(710400 Hz) = 255
cost of CPU4's OPP(710400 Hz) = 343217

Both OPPs have almost the same compute capacity but the estimated energy
per unit of utilization will be estimated to:

energy CPU0 = 191704 / 284 * 1 = 675
energy CPU4 = 343217 / 871 * 1 = 394

EM estimates that little CPU0 will consume 71% more than medium CPU4 for
the same compute capacity. According to [1], little consumes 25% less than
medium core for Coremark benchmark at those OPPs for the same duration.

Set the dynamic-power-coefficient of CPU0-3 to 105 to fix the energy model
for little CPUs.

[ Upstream commit 00de2c9f26b15f1a6f2af516dd8ec5f8d28189b7 ]

In clear_flush(), the original pte may be a present entry, so we should
use ptep_clear() to let page_table_check track the pte clearing operation,
otherwise it may cause false positive in subsequent set_pte_at().

dfadde1697 arm64/fpsimd: Only provide the length to cpufeature for xCR registers
[ Upstream commit 01948b09edc3fecf8486c57c2d2fb8b80886f3d0 ]

For both SVE and SME we abuse the generic register field comparison
support in the cpufeature code as part of our detection of unsupported
variations in the vector lengths available to PEs, reporting the maximum
vector lengths via ZCR_EL1.LEN and SMCR_EL1.LEN.  Since these are
configuration registers rather than identification registers the
assumptions the cpufeature code makes about how unknown bitfields behave
are invalid, leading to warnings when SME features like FA64 are enabled
and we hotplug a CPU:

  CPU features: SANITY CHECK: Unexpected variation in SYS_SMCR_EL1. Boot CPU: 0x0000000000000f, CPU3: 0x0000008000000f
  CPU features: Unsupported CPU feature variation detected.

SVE has no controls other than the vector length so is not yet impacted
but the same issue will apply there if any are defined.

Since the only field we are interested in having the cpufeature code
handle is the length field and we use a custom read function to obtain
the value we can avoid these warnings by filtering out all other bits
when we return the register value, if we're doing that we don't need to
bother reading the register at all and can simply use the RDVL/RDSVL
value we were filling in instead.

8d99105d6a arm64: module: Use module_init_layout_section() to spot init sections
commit f928f8b1a2496e7af95b860f9acf553f20f68f16 upstream.

Today module_frob_arch_sections() spots init sections from their
'init' prefix, and uses this to keep the init PLTs separate from the rest.

module_emit_plt_entry() uses within_module_init() to determine if a
location is in the init text or not, but this depends on whether
core code thought this was an init section.

Naturally the logic is different.

module_init_layout_section() groups the init and exit text together if
module unloading is disabled, as the exit code will never run. The result
is kernels with this configuration can't load all their modules because
there are not enough PLTs for the combined init+exit section.

This results in the following:

21614ba608 arm64/ptrace: Ensure that SME is set up for target when writing SSVE state
commit 5d0a8d2fba50e9c07cde4aad7fba28c008b07a5b upstream.

When we use NT_ARM_SSVE to either enable streaming mode or change the
vector length for a process we do not currently do anything to ensure that
there is storage allocated for the SME specific register state.  If the
task had not previously used SME or we changed the vector length then
the task will not have had TIF_SME set or backing storage for ZA/ZT
allocated, resulting in inconsistent register sizes when saving state
and spurious traps which flush the newly set register state.

We should set TIF_SME to disable traps and ensure that storage is
allocated for ZA and ZT if it is not already allocated.  This requires
modifying sme_alloc() to make the flush of any existing register state
optional so we don't disturb existing state for ZA and ZT.

commit ebceec271e552a2b05e47d8ef0597052b1a39449 upstream.

This patch fixes an issue affecting the Wifi/Bluetooth connectivity on
ROCK Pi 4 boards. Commit f471b1b2db08 ("arm64: dts: rockchip: Fix Bluetooth
on ROCK Pi 4 boards") introduced a problem with the clock configuration.
Specifically, the clock-names property of the sdio-pwrseq node was not
updated to 'lpo', causing the driver to wait indefinitely for the wrong clock
signal 'ext_clock' instead of the expected one 'lpo'. This prevented the proper
initialization of Wifi/Bluetooth chip on ROCK Pi 4 boards.

To address this, this patch updates the clock-names property of the
sdio-pwrseq node to "lpo" to align with the changes made to the bluetooth node.

This patch has been tested on ROCK Pi 4B.
