The WDAT watchdog driver uses functionality provided by the watchdog timer core but it did not select it explicitly. This results following linker error when only WDAT_WDT is enabled in Kconfig: drivers/built-in.o: In function `wdat_wdt_probe': drivers/watchdog/wdat_wdt.c:444: undefined reference to `devm_watchdog_register_device' Fix this by explicitly selecting WATCHDOG_CORE when WDAT watchdog driver is enabled.

With the new (in 4.9) option to use a virtually-mapped stack (CONFIG_VMAP_STACK), stack buffers cannot be used as input/output for the scatterlist crypto API because they may not be directly mappable to struct page. get_crypt_info() was using a stack buffer to hold the output from the encryption operation used to derive the per-file key.

Recently algif_hash has been changed to allow null hashes. This triggers a bug when used with an shash algorithm whereby it will cause a crash during the digest operation. This patch fixes it by avoiding the digest operation and instead doing an init followed by a final which avoids the buggy code in shash. This patch also ensures that the result buffer is freed after an error so that it is not returned as a genuine hash result on the next recv call. The shash/ahash wrapper code will be fixed later to handle this case correctly.

KVM calls kvm_pmu_set_counter_event_type() when PMCCFILTR is configured. But this function can't deals with PMCCFILTR correctly because the evtCount bits of PMCCFILTR, which is reserved 0, conflits with the SW_INCR event type of other PMXEVTYPER<n> registers. To fix it, when eventsel == 0, this function shouldn't return immediately; instead it needs to check further if select_idx is ARMV8_PMU_CYCLE_IDX. Another issue is that KVM shouldn't copy the eventsel bits of PMCCFILTER blindly to attr.config. Instead it ought to convert the request to the "cpu cycle" event type (i.e. 0x11). To support this patch and to prevent duplicated definitions, a limited set of ARMv8 perf event types were relocated from perf_event.c to asm/perf_event.h.
