[ Upstream commit b334456e ] Vendor specific setup_clocks ops may depend on clocks managed by ufshcd driver so if the vendor specific setup_clocks callback is called when the required clocks are turned off, it results into unclocked register access. This change make sure that required clocks are enabled before vendor specific setup_clocks callback is called. Signed-off-by:

[ Upstream commit 36dd26e0 ] Improve fscrypt read performance by switching the decryption workqueue from bound to unbound. With the bound workqueue, when multiple bios completed on the same CPU, they were decrypted on that same CPU. But with the unbound queue, they are now decrypted in parallel on any CPU. Although fscrypt read performance can be tough to measure due to the many sources of variation, this change is most beneficial when decryption is slow, e.g. on CPUs without AES instructions. For example, I timed tarring up encrypted directories on f2fs. On x86 with AES-NI instructions disabled, the unbound workqueue improved performance by about 25-35%, using 1 to NUM_CPUs jobs with 4 or 8 CPUs available. But with AES-NI enabled, performance was unchanged to within ~2%. I also did the same test on a quad-core ARM CPU using xts-speck128-neon encryption. There performance was usually about 10% better with the unbound workqueue, bringing it closer to the unencrypted speed. The unbound workqueue may be worse in some cases due to worse locality, but I think it's still the better default. dm-crypt uses an unbound workqueue by default too, so this change makes fscrypt match.

[ Upstream commit 1898eb61 ] The ARM CCN PMU driver uses dev_warn() to complain about parameters in the user-provided perf_event_attr. This means that under normal operation (e.g. a single invocation of the perf tool), a number of messages warnings may be logged to dmesg. Tools may issue multiple syscalls to probe for feature support, and multiple applications (from multiple users) can attempt to open events simultaneously, so this is not very helpful, even if a user happens to have access to dmesg. Worse, this can push important information out of the dmesg ring buffer, and can significantly slow down syscall fuzzers, vastly increasing the time it takes to find critical bugs. Demote the dev_warn() instances to dev_dbg(), as is the case for all other PMU drivers under drivers/perf/. Users who wish to debug PMU event initialisation can enable dynamic debug to receive these messages. Signed-off-by:

[ Upstream commit 4ea69b2f ] For multi-function programs, loading the address of a callee function to a register requires emitting instructions whose count varies from one to five depending on the nature of the address. Since we come to know of the callee's address only before the extra pass, the number of instructions required to load this address may vary from what was previously generated. This can make the JITed image grow or shrink. To avoid this, we should generate a constant five-instruction when loading function addresses by padding the optimized load sequence with NOPs.

[ Upstream commit 72cd4cc2 ] The nvme timeout handling doesn't do anything if the pci channel is offline, which is the case when recovering from PCI error event, so it was a bad idea to sync the controller reset in this state.

[ Upstream commit 3d3a2e61 ] Currently the code assumes that there's an implied barrier by the sequence of code preceding the wakeup, namely the mutex unlock. As Nikolay pointed out: I think this is wrong (not your code) but the original assumption that the RELEASE semantics provided by mutex_unlock is sufficient. According to memory-barriers.txt: Section 'LOCK ACQUISITION FUNCTIONS' states: (2) RELEASE operation implication: Memory operations issued before the RELEASE will be completed before the RELEASE operation has completed. Memory operations issued after the RELEASE *may* be completed before the RELEASE operation has completed. (I've bolded the may portion) The example given there: As an example, consider the following: *A = a; *B = b; ACQUIRE *C = c; *D = d; RELEASE *E = e; *F = f; The following sequence of events is acceptable: ACQUIRE, {*F,*A}, *E, {*C,*D}, *B, RELEASE So if we assume that *C is modifying the flag which the waitqueue is checking, and *E is the actual wakeup, then those accesses can be re-ordered... IMHO this code should be considered broken... Signed-off-by:
