Matthijs Kooijman authored
The pinctrl-single driver handles pin_config_set by looking up the requested setting in a DT-defined lookup table, which defines what bits correspond to each setting. There is no way to add PIN_CONFIG_BIAS_DISABLE entries to the table, since there is instead code to disable the bias by applying the disable values of both the pullup and pulldown entries in the table. However, this code is inside the table-lookup loop, so it would only execute if there is an entry for PIN_CONFIG_BIAS_DISABLE in the table, which can never exist, so this code never runs. This commit lifts the offending code out of the loop, so it just executes directly whenever PIN_CONFIG_BIAS_DISABLE is requested, skippipng the table lookup loop. This also introduces a new `param` variable to make the code slightly more readable. This bug seems to have existed when this code was first merged in commit 9dddb4df ("pinctrl: single: support generic pinconf"). Earlier versions of this patch did have an entry for PIN_CONFIG_BIAS_DISABLE in the lookup table, but that was removed, which is probably how this bug was introduced. Signed-off-by:

The goal is to extend the active period of pinctrl. Some devices may need active pinctrl after suspend() and/or before resume(). So move suspend()/resume() to suspend_noirq()/resume_noirq() in order to have active pinctrl until suspend_noirq() (included), and from resume_noirq() (included). The deprecated API has been removed to use the new one (dev_pm_ops struct). No need to check the pointer returned by dev_get_drvdata(), as platform_set_drvdata() is called during the probe.

Even the driver already has implemented pin_dbg_show, it could be helpful to implement pin_conf_get for a more generic behavior. Contrary to the BCM2711, the BCM2835 SOC doesn't allow to read the bias config, so the implementation is limited to the basics. Keep ENOTSUPP here, because it's only used internally. Signed-off-by:

Pull x86 fixes from Thomas Gleixner: - Ensure that the encryption mask at boot is properly propagated on 5-level page tables, otherwise the PGD entry is incorrectly set to non-encrypted, which causes system crashes during boot. - Undo the deferred 5-level page table setup as it cannot work with memory encryption enabled. - Prevent inconsistent XFD state on CPU hotplug, where the MSR is reset to the default value but the cached variable is not, so subsequent comparisons might yield the wrong result and as a consequence the result prevents updating the MSR. - Register the local APIC address only once in the MPPARSE enumeration to prevent triggering the related WARN_ONs() in the APIC and topology code. - Handle the case where no APIC is found gracefully by registering a fake APIC in the topology code. That makes all related topology functions work correctly and does not affect the actual APIC driver code at all. - Don't evaluate logical IDs during early boot as the local APIC IDs are not yet enumerated and the invoked function returns an error code. Nothing requires the logical IDs before the final CPUID enumeration takes place, which happens after the enumeration. - Cure the fallout of the per CPU rework on UP which misplaced the copying of boot_cpu_data to per CPU data so that the final update to boot_cpu_data got lost which caused inconsistent state and boot crashes. - Use copy_from_kernel_nofault() in the kprobes setup as there is no guarantee that the address can be safely accessed. - Reorder struct members in struct saved_context to work around another kmemleak false positive - Remove the buggy code which tries to update the E820 kexec table for setup_data as that is never passed to the kexec kernel. - Update the resource control documentation to use the proper units. - Fix a Kconfig warning observed with tinyconfig * tag 'x86-urgent-2024-03-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/boot/64: Move 5-level paging global variable assignments back x86/boot/64: Apply encryption mask to 5-level pagetable update x86/cpu: Add model number for another Intel Arrow Lake mobile processor x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD Documentation/x86: Document that resctrl bandwidth control units are MiB x86/mpparse: Register APIC address only once x86/topology: Handle the !APIC case gracefully x86/topology: Don't evaluate logical IDs during early boot x86/cpu: Ensure that CPU info updates are propagated on UP kprobes/x86: Use copy_from_kernel_nofault() to read from unsafe address x86/pm: Work around false positive kmemleak report in msr_build_context() x86/kexec: Do not update E820 kexec table for setup_data x86/config: Fix warning for 'make ARCH=x86_64 tinyconfig'
