2019-10-21fscrypt: remove struct fscrypt_ctxEric Biggers
Now that ext4 and f2fs implement their own post-read workflow that supports both fscrypt and fsverity, the fscrypt-only workflow based around struct fscrypt_ctx is no longer used. So remove the unused code. This is based on a patch from Chandan Rajendra's "Consolidate FS read I/O callbacks code" patchset, but rebased onto the latest kernel, folded __fscrypt_decrypt_bio() into fscrypt_decrypt_bio(), cleaned up fscrypt_initialize(), and updated the commit message.

2019-10-21arm64: Retrieve stolen time as paravirtualized guestSteven Price
Enable paravirtualization features when running under a hypervisor supporting the PV_TIME_ST hypercall. For each (v)CPU, we ask the hypervisor for the location of a shared page which the hypervisor will use to report stolen time to us. We set pv_time_ops to the stolen time function which simply reads the stolen value from the shared page for a VCPU. We guarantee single-copy atomicity using READ_ONCE which means we can also read the stolen time for another VCPU than the currently running one while it is potentially being updated by the hypervisor.

2019-10-21arm/arm64: Provide a wrapper for SMCCC 1.1 callsSteven Price
SMCCC 1.1 calls may use either HVC or SMC depending on the PSCI conduit. Rather than coding this in every call site, provide a macro which uses the correct instruction. The macro also handles the case where no conduit is configured/available returning a not supported error in res, along with returning the conduit used for the call. This allow us to remove some duplicated code and will be useful later when adding paravirtualized time hypervisor calls.

2019-10-21KVM: arm64: Support stolen time reporting via shared structureSteven Price
Implement the service call for configuring a shared structure between a VCPU and the hypervisor in which the hypervisor can write the time stolen from the VCPU's execution time by other tasks on the host. User space allocates memory which is placed at an IPA also chosen by user space. The hypervisor then updates the shared structure using kvm_put_guest() to ensure single copy atomicity of the 64-bit value reporting the stolen time in nanoseconds. Whenever stolen time is enabled by the guest, the stolen time counter is reset. The stolen time itself is retrieved from the sched_info structure maintained by the Linux scheduler code. We enable SCHEDSTATS when selecting KVM Kconfig to ensure this value is meaningful. Signed-off-by: Steven Price <steven.price@arm.com> Signed-off-by: Marc Zyngier <maz@kernel.org>

2019-10-21jbd2: Make state lock a spinlockThomas Gleixner
Bit-spinlocks are problematic on PREEMPT_RT if functions which might sleep on RT, e.g. spin_lock(), alloc/free(), are invoked inside the lock held region because bit spinlocks disable preemption even on RT. A first attempt was to replace state lock with a spinlock placed in struct buffer_head and make the locking conditional on PREEMPT_RT and DEBUG_BIT_SPINLOCKS. Jan pointed out that there is a 4 byte hole in struct journal_head where a regular spinlock fits in and he would not object to convert the state lock to a spinlock unconditionally. Aside of solving the RT problem, this also gains lockdep coverage for the journal head state lock (bit-spinlocks are not covered by lockdep as it's hard to fit a lockdep map into a single bit). The trivial change would have been to convert the jbd_*lock_bh_state() inlines, but that comes with the downside that these functions take a buffer head pointer which needs to be converted to a journal head pointer which adds another level of indirection. As almost all functions which use this lock have a journal head pointer readily available, it makes more sense to remove the lock helper inlines and write out spin_*lock() at all call sites. Fixup all locking comments as well.

2019-10-21cpufreq: Use per-policy frequency QoSRafael J. Wysocki
Replace the CPU device PM QoS used for the management of min and max frequency constraints in cpufreq (and its users) with per-policy frequency QoS to avoid problems with cpufreq policies covering more then one CPU. Namely, a cpufreq driver is registered with the subsys interface which calls cpufreq_add_dev() for each CPU, starting from CPU0, so currently the PM QoS notifiers are added to the first CPU in the policy (i.e. CPU0 in the majority of cases). In turn, when the cpufreq driver is unregistered, the subsys interface doing that calls cpufreq_remove_dev() for each CPU, starting from CPU0, and the PM QoS notifiers are only removed when cpufreq_remove_dev() is called for the last CPU in the policy, say CPUx, which as a rule is not CPU0 if the policy covers more than one CPU. Then, the PM QoS notifiers cannot be removed, because CPUx does not have them, and they are still there in the device PM QoS notifiers list of CPU0, which prevents new PM QoS notifiers from being registered for CPU0 on the next attempt to register the cpufreq driver. The same issue occurs when the first CPU in the policy goes offline before unregistering the driver. After this change it does not matter which CPU is the policy CPU at the driver registration time and whether or not it is online all the time, because the frequency QoS is per policy and not per CPU.

2019-10-21PM: QoS: Introduce frequency QoSRafael J. Wysocki
Introduce frequency QoS, based on the "raw" low-level PM QoS, to represent min and max frequency requests and aggregate constraints. The min and max frequency requests are to be represented by struct freq_qos_request objects and the aggregate constraints are to be represented by struct freq_constraints objects. The latter are expected to be initialized with the help of freq_constraints_init(). The freq_qos_read_value() helper is defined to retrieve the aggregate constraints values from a given struct freq_constraints object and there are the freq_qos_add_request(), freq_qos_update_request() and freq_qos_remove_request() helpers to manipulate the min and max frequency requests. It is assumed that the the helpers will not run concurrently with each other for the same struct freq_qos_request object, so if that may be the case, their uses must ensure proper synchronization between them (e.g. through locking). In addition, freq_qos_add_notifier() and freq_qos_remove_notifier() are provided to add and remove notifiers that will trigger on aggregate constraint changes to and from a given struct freq_constraints object, respectively.

There is no need to keep a pointer to the platform device. Currently there are no users of it directly, and if there will be in the future we may restore it from pointer to the struct device. Convert all users at the same time.

2019-10-18symbol namespaces: revert to previous __ksymtab name schemeMatthias Maennich
The introduction of Symbol Namespaces changed the naming schema of the __ksymtab entries from __kysmtab__symbol to __ksymtab_NAMESPACE.symbol. That caused some breakages in tools that depend on the name layout in either the binaries(vmlinux,*.ko) or in System.map. E.g. kmod's depmod would not be able to read System.map without a patch to support symbol namespaces. A warning reported by depmod for namespaced symbols would look like depmod: WARNING: [...]/uas.ko needs unknown symbol usb_stor_adjust_quirks In order to address this issue, revert to the original naming scheme and rather read the __kstrtabns_<symbol> entries and their corresponding values from __ksymtab_strings to update the namespace values for symbols. After having read all symbols and handled them in handle_modversions(), the symbols are created. In a second pass, read the __kstrtabns_ entries and update the namespaces accordingly. Fixes: 8651ec01daed ("module: add support for symbol namespaces.")

2019-10-18linkage: Introduce new macros for assembler symbolsJiri Slaby
Introduce new C macros for annotations of functions and data in assembly. There is a long-standing mess in macros like ENTRY, END, ENDPROC and similar. They are used in different manners and sometimes incorrectly. So introduce macros with clear use to annotate assembly as follows: a) Support macros for the ones below SYM_T_FUNC -- type used by assembler to mark functions SYM_T_OBJECT -- type used by assembler to mark data SYM_T_NONE -- type used by assembler to mark entries of unknown type They are defined as STT_FUNC, STT_OBJECT, and STT_NOTYPE respectively. According to the gas manual, this is the most portable way. I am not sure about other assemblers, so this can be switched back to %function and %object if this turns into a problem. Architectures can also override them by something like ", @function" if they need. SYM_A_ALIGN, SYM_A_NONE -- align the symbol? SYM_L_GLOBAL, SYM_L_WEAK, SYM_L_LOCAL -- linkage of symbols b) Mostly internal annotations, used by the ones below SYM_ENTRY -- use only if you have to (for non-paired symbols) SYM_START -- use only if you have to (for paired symbols) SYM_END -- use only if you have to (for paired symbols) c) Annotations for code SYM_INNER_LABEL_ALIGN -- only for labels in the middle of code SYM_INNER_LABEL -- only for labels in the middle of code SYM_FUNC_START_LOCAL_ALIAS -- use where there are two local names for one function SYM_FUNC_START_ALIAS -- use where there are two global names for one function SYM_FUNC_END_ALIAS -- the end of LOCAL_ALIASed or ALIASed function SYM_FUNC_START -- use for global functions SYM_FUNC_START_NOALIGN -- use for global functions, w/o alignment SYM_FUNC_START_LOCAL -- use for local functions SYM_FUNC_START_LOCAL_NOALIGN -- use for local functions, w/o alignment SYM_FUNC_START_WEAK -- use for weak functions SYM_FUNC_START_WEAK_NOALIGN -- use for weak functions, w/o alignment SYM_FUNC_END -- the end of SYM_FUNC_START_LOCAL, SYM_FUNC_START, SYM_FUNC_START_WEAK, ... For functions with special (non-C) calling conventions: SYM_CODE_START -- use for non-C (special) functions SYM_CODE_START_NOALIGN -- use for non-C (special) functions, w/o alignment SYM_CODE_START_LOCAL -- use for local non-C (special) functions SYM_CODE_START_LOCAL_NOALIGN -- use for local non-C (special) functions, w/o alignment SYM_CODE_END -- the end of SYM_CODE_START_LOCAL or SYM_CODE_START d) For data SYM_DATA_START -- global data symbol SYM_DATA_START_LOCAL -- local data symbol SYM_DATA_END -- the end of the SYM_DATA_START symbol SYM_DATA_END_LABEL -- the labeled end of SYM_DATA_START symbol SYM_DATA -- start+end wrapper around simple global data SYM_DATA_LOCAL -- start+end wrapper around simple local data ========== The macros allow to pair starts and ends of functions and mark functions correctly in the output ELF objects. All users of the old macros in x86 are converted to use these in further patches. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Borislav Petkov <bp@suse.de> Acked-by: Rafael J.
