It's preffered to use group's ->is_visible callback, so we do not need to use condition attribute assignment.

IMC uncore unit can only be accessed via MMIO on Snow Ridge. The MMIO space of IMC uncore is at the specified offsets from the MEM0_BAR. Add snr_uncore_get_mc_dev() to locate the PCI device with MMIO_BASE and MEM0_BAR register. Add new ops to access the IMC registers via MMIO. Add 3 new free running counters for clocks, read and write bandwidth.

The client IMC block is accessed by MMIO. Current code uses an informal way to access the block, which is not recommended. Clean up the code by using __iomem annotation and the accessor functions (read[lq]()). Move exit_box() and read_counter() to generic code, which can be shared with the server code later.

A new MMIO type uncore box is introduced on Snow Ridge server. The counters of MMIO type uncore box can only be accessed by MMIO. Add a new uncore type, uncore_mmio_uncores, for MMIO type uncore blocks. Support MMIO type uncore blocks in CPU hot plug. The MMIO space has to be map/unmap for the first/last CPU. The context also need to be migrated if the bind CPU changes. Add mmio_init() to init and register PMUs for MMIO type uncore blocks. Add a helper to calculate the box_ctl address. The helpers which calculate ctl/ctr can be shared with PCI type uncore blocks.

For uncore box which can only be accessed by MSR, its reference box->refcnt is updated in CPU hot plug. The uncore boxes need to be initalized and exited accordingly for the first/last CPU of a socket. Starts from Snow Ridge server, a new type of uncore box is introduced, which can only be accessed by MMIO. The driver needs to map/unmap MMIO space for the first/last CPU of a socket. Extract the codes of box ref/unref and init/exit for reuse later. There is no functional change.

The uncore subsystem on Snow Ridge is similar as previous SKX server. The uncore units on Snow Ridge include Ubox, Chabox, IIO, IRP, M2PCIE, PCU, M2M, PCIE3 and IMC. - The config register encoding and pci device IDs are changed. - For CHA, the umask_ext and filter_tid fields are changed. - For IIO, the ch_mask and fc_mask fields are changed. - For M2M, the mask_ext field is changed. - Add new PCIe3 unit for PCIe3 root port which provides the interface between PCIe devices, plugged into the PCIe port, and the components (in M2IOSF). - IMC can only be accessed via MMIO on Snow Ridge now. Current common code doesn't support it yet. IMC will be supported in following patches. - There are 9 free running counters for IIO CLOCKS and bandwidth In. - Full uncore event list is not published yet. Event constrain is not included in this patch. It will be added later separately.

Counting with invalid event coding for free-running counter may cause OOPs, e.g. uncore_iio_free_running_0/event=1/. Current code only validate the event with free-running event format, event=0xff,umask=0xXY. Non-free-running event format never be checked for the PMU with free-running counters. Add generic hw_config() to check and reject the invalid event coding for free-running PMU.

Add the CPUID enumeration for Intel's de-feature bits to accommodate passing these de-features through to kvm guests. These de-features are (from SDM vol 1, section 8.1.8): - X86_FEATURE_FDP_EXCPTN_ONLY: If CPUID.(EAX=07H,ECX=0H):EBX[bit 6] = 1, the data pointer (FDP) is updated only for the x87 non-control instructions that incur unmasked x87 exceptions. - X86_FEATURE_ZERO_FCS_FDS: If CPUID.(EAX=07H,ECX=0H):EBX[bit 13] = 1, the processor deprecates FCS and FDS; it saves each as 0000H.

This driver does not support reading more than 255 bytes at once because the register for storing the number of bytes to read is only 8 bits. Add a max_read_len quirk to enforce this. This was found when using this driver with the SFP driver, which was previously reading all 256 bytes in the SFP EEPROM in one transaction. This caused a bunch of hard-to-debug errors in the xiic driver since the driver/logic was treating the number of bytes to read as zero. Rejecting transactions that aren't supported at least allows the problem to be diagnosed more easily.

The lockref cmpxchg loop is unbound as long as the spinlock is not taken. Depending on the hardware implementation of compare-and-swap a high number of loop retries might happen. Add an upper bound to the loop to force the fallback to spinlocks after some time. A retry value of 100 should not impact any hardware that does not have this issue. With the retry limit the performance of an open-close testcase improved between 60-70% on ThunderX2.

Architectures that support memory tagging have a need to perform untagging (stripping the tag) in various parts of the kernel. This patch adds an untagged_addr() macro, which is defined as noop for architectures that do not support memory tagging. The oncoming patch series will define it at least for sparc64 and arm64.

Pull power management fixes from Rafael Wysocki: "These fix a crash during resume from hibernation introduced during the 4.19 cycle, cause the new Performance and Energy Bias Hint (EPB) code to be built only if CONFIG_PM is set and add a few missing kerneldoc comments. Specifics: - Fix a crash that occurs when a kernel with 'nosmt' in the command line is used to resume the system from hibernation (as the "restore" kernel), because memory mapping differences between the restore and image kernels cause SMT siblings to be woken up from idle states and subsequently they try to fetch instructions from incorrect memory locations (Jiri Kosina). - Cause the new Performance and Energy Bias Hint (EPB) code to be built only if CONFIG_PM is set, because that code is not really necessary otherwise (Rafael Wysocki). - Add kerneldoc comments to documents some helper functions related to system-wide suspend to avoid possible confusion regarding their purpose (Rafael Wysocki)" * tag 'pm-5.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: x86/power: Fix 'nosmt' vs hibernation triple fault during resume PM: sleep: Add kerneldoc comments to some functions x86: intel_epb: Do not build when CONFIG_PM is unset

get_desc() computes a pointer into the LDT while holding a lock that protects the LDT from being freed, but then drops the lock and returns the (now potentially dangling) pointer to its caller. Fix it by giving the caller a copy of the LDT entry instead.
