Commit 785b5bb ("PM: AVS: Drop the avs directory and the corresponding Kconfig") moved AVS code to SOC-specific folders, and removed corresponding Kconfig from drivers/power, leaving original POWER_AVS config option enabled in omap2plus_defconfig file. Remove the option, which has no references in the tree anymore.

On the GTA04A5 od->_driver_status was not set to BUS_NOTIFY_BIND_DRIVER during probe of the second mmc used for wifi. Therefore omap_device_late_idle idled the device during probing causing oopses when accessing the registers. It was not set because od->_state was set to OMAP_DEVICE_STATE_IDLE in the notifier callback. Therefore set od->_driver_status also in that case. This came apparent after commit 21b2cec ("mmc: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in v4.4") causing this oops: omap_hsmmc 480b4000.mmc: omap_device_late_idle: enabled but no driver.

We reset the guest's view of PMCR_EL0 unconditionally, based on the host's view of this register. It is however legal for an implementation not to provide any PMU, resulting in an UNDEF. The obvious fix is to skip the reset of this shadow register when no PMU is available, sidestepping the issue entirely. If no PMU is available, the guest is not able to request a virtual PMU anyway, so not doing nothing is the right thing to do! It is unlikely that this bug can hit any HW implementation though, as they all provide a PMU. It has been found using nested virt with the host KVM not implementing the PMU itself.

PSCI driver exposes a struct containing the PSCI v0.1 function IDs configured in the DT. However, the struct does not convey the information whether these were set from DT or contain the default value zero. This could be a problem for PSCI proxy in KVM protected mode. Extend config passed to KVM with a bit mask with individual bits set depending on whether the corresponding function pointer in psci_ops is set, eg. set bit for PSCI_CPU_SUSPEND if psci_ops.cpu_suspend != NULL. Previously config was split into multiple global variables. Put everything into a single struct for convenience.

Although there is nothing wrong with the current host PSCI relay implementation, we can clean it up and remove some of the helpers that do not improve the overall readability of the legacy PSCI 0.1 handling. Opportunity is taken to turn the bitmap into a set of booleans, and creative use of preprocessor macros make init and check more concise/readable.

The API documentation states that general error codes are not detailed, but errors with specific meanings are. On arm64, KVM_RUN can return error numbers with a different meaning than what is described by POSIX or the C99 standard (as taken from man 3 errno). Absent from the newly documented error codes is ERANGE which can be returned when making a change to the EL2 stage 1 tables if the address is larger than the largest supported input address. Assuming no bugs in the implementation, that is not possible because the input addresses which are mapped are the result of applying the macro kern_hyp_va() on kernel virtual addresses.

kvm_timer_enable() is called in kvm_vcpu_first_run_init() after kvm_vgic_map_resources() if the VGIC wasn't ready. kvm_vgic_map_resources() is the only place where kvm->arch.vgic.ready is set to true. For a v2 VGIC, kvm_vgic_map_resources() will attempt to initialize the VGIC and set the initialized flag. For a v3 VGIC, kvm_vgic_map_resources() will return an error code if the VGIC isn't already initialized. The end result is that if we've reached kvm_timer_enable(), the VGIC is initialzed and ready and vgic_initialized() will always be true, so remove this check.

kvm_vgic_map_resources() is called when a VCPU if first run and it maps all
the VGIC MMIO regions. To prevent double-initialization, the VGIC uses the
ready variable to keep track of the state of resources and the global KVM
mutex to protect against concurrent accesses. After the lock is taken, the
variable is checked again in case another VCPU took the lock between the
current VCPU reading ready equals false and taking the lock.
The double-checked lock pattern is spread across four different functions:
in kvm_vcpu_first_run_init(), in kvm_vgic_map_resource() and in
vgic_{v2,v3}_map_resources(), which makes it hard to reason about and
introduces minor code duplication. Consolidate the checks in
kvm_vgic_map_resources(), where the lock is taken.
No functional change intended.

KVM_ARM_VCPU_INIT ioctl calls kvm_reset_vcpu(), which in turn resets the PMU with a call to kvm_pmu_vcpu_reset(). The function zeroes the PMU chained counters bitmap and stops all the counters with a perf event attached. Because it is called before the VCPU has had the chance to run, no perf events are in use and none are released. kvm_arm_pmu_v3_enable(), called by kvm_vcpu_first_run_init() only if the VCPU has been initialized, also resets the PMU. kvm_pmu_vcpu_reset() in this case does the exact same thing as the previous call, so remove it.

The __init annotations on hyp_cpu_pm_{init,exit} are obviously incorrect,

Nothing really bad happens as we never execute that code outside of the

isn't __init itself. Oh well.

In kvm_mmu_notifier_invalidate_range_start(), tlbs_dirty is used as:
need_tlb_flush |= kvm->tlbs_dirty;
with need_tlb_flush's type being int and tlbs_dirty's type being long.
It means that tlbs_dirty is always used as int and the higher 32 bits
is useless. We need to check tlbs_dirty in a correct way and this
change checks it directly without propagating it to need_tlb_flush.
Note: it's _extremely_ unlikely this neglecting of higher 32 bits can
cause problems in practice. It would require encountering tlbs_dirty
on a 4 billion count boundary, and KVM would need to be using shadow
paging or be running a nested guest.

Many TDP MMU functions which need to perform some action on all TDP MMU roots hold a reference on that root so that they can safely drop the MMU lock in order to yield to other threads. However, when releasing the reference on the root, there is a bug: the root will not be freed even if its reference count (root_count) is reduced to 0. To simplify acquiring and releasing references on TDP MMU root pages, and to ensure that these roots are properly freed, move the get/put operations into another TDP MMU root iterator macro. Moving the get/put operations into an iterator macro also helps simplify control flow when a root does need to be freed. Note that using the list_for_each_entry_safe macro would not have been appropriate in this situation because it could keep a pointer to the next root across an MMU lock release + reacquire, during which time that root could be freed.

Typically under KVM, an AP is booted using the INIT-SIPI-SIPI sequence, where the guest vCPU register state is updated and then the vCPU is VMRUN to begin execution of the AP. For an SEV-ES guest, this won't work because the guest register state is encrypted. Following the GHCB specification, the hypervisor must not alter the guest register state, so KVM must track an AP/vCPU boot. Should the guest want to park the AP, it must use the AP Reset Hold exit event in place of, for example, a HLT loop. First AP boot (first INIT-SIPI-SIPI sequence): Execute the AP (vCPU) as it was initialized and measured by the SEV-ES support. It is up to the guest to transfer control of the AP to the proper location. Subsequent AP boot: KVM will expect to receive an AP Reset Hold exit event indicating that the vCPU is being parked and will require an INIT-SIPI-SIPI sequence to awaken it. When the AP Reset Hold exit event is received, KVM will place the vCPU into a simulated HLT mode. Upon receiving the INIT-SIPI-SIPI sequence, KVM will make the vCPU runnable. It is again up to the guest to then transfer control of the AP to the proper location. To differentiate between an actual HLT and an AP Reset Hold, a new MP state is introduced, KVM_MP_STATE_AP_RESET_HOLD, which the vCPU is placed in upon receiving the AP Reset Hold exit event. Additionally, to communicate the AP Reset Hold exit event up to userspace (if needed), a new exit reason is introduced, KVM_EXIT_AP_RESET_HOLD. A new x86 ops function is introduced, vcpu_deliver_sipi_vector, in order to accomplish AP booting. For VMX, vcpu_deliver_sipi_vector is set to the original SIPI delivery function, kvm_vcpu_deliver_sipi_vector(). SVM adds a new function that, for non SEV-ES guests, invokes the original SIPI delivery function, kvm_vcpu_deliver_sipi_vector(), but for SEV-ES guests, implements the logic above.

Pull power management fixes from Rafael Wysocki:
"These address two issues in the intel_pstate driver and one in the
powernow-k8 cpufreq driver.
Specifics:
- Make the powernow-k8 cpufreq driver avoid calling
cpufreq_cpu_get(), which theoretically may return NULL, to get a
policy pointer that is known to it already (Colin Ian King)
- Drop two functions that are not used any more from the intel_pstate
driver (Lukas Bulwahn)
- Make intel_pstate check the HWP capabilities to get the maximum
available P-state in the passive mode to avoid using a stale value
of it in case of out-of-band updates (Rafael Wysocki)"
* tag 'pm-5.11-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
cpufreq: intel_pstate: remove obsolete functions
cpufreq: powernow-k8: pass policy rather than use cpufreq_cpu_get()
cpufreq: intel_pstate: Use HWP capabilities in intel_cpufreq_adjust_perf()

Pull ACPI fixes from Rafael Wysocki:
"These address two build issues and drop confusing text from a couple
of Kconfig entries.
Specifics:
- Drop two local variables that are never read and the code updating
their values from the x86 suspend-to-idle code (Rafael Wysocki)
- Add empty stub of an ACPI helper function to avoid build issues
when CONFIG_ACPI is not set (Shawn Guo)
- Remove confusing text regarding modules from Kconfig entries that
correspond to non-modular code (Peter Robinson)"
* tag 'acpi-5.11-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
ACPI: Update Kconfig help text for items that are no longer modular
ACPI: scan: add stub acpi_create_platform_device() for !CONFIG_ACPI
ACPI: PM: s2idle: Drop unused local variables and related code
…rnel/git/rafael/linux-pm Pull device properties framework fixes from Rafael Wysocki: "Revert a problematic commit that went in during the 5.10 cycle and improve the kerneldoc description of the function affected by it (both changes from Bard Liao)" * tag 'devprop-5.11-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: device property: add description of fwnode cases Revert "device property: Keep secondary firmware node secondary by type"

Use BPF_TRAMP_F_INDIRECT flag to detect struct ops and emit proper prologue and epilogue for this case. With this patch, all of the struct_ops related testcases (except struct_ops_multi_pages) passed on LoongArch. The testcase struct_ops_multi_pages failed is because the actual image_pages_cnt is 40 which is bigger than MAX_TRAMP_IMAGE_PAGES. Before: $ sudo ./test_progs -t struct_ops -d struct_ops_multi_pages ... WATCHDOG: test case struct_ops_module/struct_ops_load executes for 10 seconds... After: $ sudo ./test_progs -t struct_ops -d struct_ops_multi_pages ... #15 bad_struct_ops:OK ... #399 struct_ops_autocreate:OK ... #400 struct_ops_kptr_return:OK ... #401 struct_ops_maybe_null:OK ... #402 struct_ops_module:OK ... #404 struct_ops_no_cfi:OK ... #405 struct_ops_private_stack:SKIP ... #406 struct_ops_refcounted:OK Summary: 8/25 PASSED, 3 SKIPPED, 0 FAILED Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
