[ Upstream commit 00b39f69 ] If for whatever reason the dasd_eckd_check_characteristics() function exits after at least some paths have their configuration data allocated those data is never freed again. In the error case the device->private pointer is set to NULL and dasd_eckd_uncheck_device() will exit without freeing the path data because of this NULL pointer. Fix by calling dasd_eckd_clear_conf_data() for error cases. Also use dasd_eckd_clear_conf_data() in dasd_eckd_uncheck_device() to avoid code duplication. Reported-by:

[ Upstream commit dd4b3c83 ] The max data count (mdc) is an unsigned 16-bit integer value as per AR documentation and is received via ccw_device_get_mdc() for a specific path mask from the CIO layer. The function itself also always returns a positive mdc value or 0 in case mdc isn't supported or couldn't be determined. Though, the comment for this function describes a negative return value to indicate failures. As a result, the DASD device driver interprets the return value of ccw_device_get_mdc() incorrectly. The error case is essentially a dead code path. To fix this behaviour, check explicitly for a return value of 0 and change the comment for ccw_device_get_mdc() accordingly. This fix merely enables the error code path in the DASD functions get_fcx_max_data() and verify_fcx_max_data(). The actual functionality stays the same and is still correct. Reviewed-by:

[ Upstream commit 04646aeb ] Anything that walks all inodes on sb->s_inodes list without rescheduling risks softlockups.

This also consistently moves the cond_resched() calls to the bottom of each loop in cases where it already exists. One loop remains: remove_dquot_ref(), because I'm not quite sure how to deal with that one w/o taking the i_lock. Signed-off-by:

[ Upstream commit 92ca7da4 ] Commit: ccbebba4 ("perf/x86/intel/pt: Bypass PT vs. LBR exclusivity if the core supports it") skips the PT/LBR exclusivity check on CPUs where PT and LBRs coexist, but also inadvertently skips the active_events bump for PT in that case, which is a bug. If there aren't any hardware events at the same time as PT, the PMI handler will ignore PT PMIs, as active_events reads zero in that case, resulting in the "Uhhuh" spurious NMI warning and PT data loss. Fix this by always increasing active_events for PT events. Fixes: ccbebba4 ("perf/x86/intel/pt: Bypass PT vs. LBR exclusivity if the core supports it") Reported-by:

The latter one takes effect when the core temperature is at least 85 degree celsius or higher So the current critical trip point doesn't make sense, because the thermal shutdown appears before the firmware has a chance to throttle the ARM core(s).

[ Upstream commit db3b665d ] The existing rbtree implementation might store consecutive elements where the closing element and the opening element might overlap, eg. [ a, a+1) [ a+1, a+2) This patch removes the optimization for non-anonymous sets in the exact matching case, where it is assumed to stop searching in case that the closing element is found. Instead, invalidate candidate interval and keep looking further in the tree. The lookup/get operation might return false, while there is an element in the rbtree. Moreover, the get operation returns true as if a+2 would be in the tree. This happens with named sets after several set updates. The existing lookup optimization (that only works for the anonymous sets) might not reach the opening [ a+1,... element if the closing ...,a+1) is found in first place when walking over the rbtree. Hence, walking the full tree in that case is needed. This patch fixes the lookup and get operations.

We can't use core cpumask to set policy->cpus in ve_spc_cpufreq_init() anymore as it gets called via cpuhp_cpufreq_online()->cpufreq_online() ->cpufreq_driver->init() and the cpumask gets updated upon CPU hotplug operations. It also may cause issues when the vexpress_spc_cpufreq driver is built as a module. Since ve_spc_clk_init is built-in device initcall, we should be able to use the same topology_core_cpumask to set the opp sharing cpumask via dev_pm_opp_set_sharing_cpus and use the same later in the driver via dev_pm_opp_get_sharing_cpus.
