Merge tag 'powerpc-5.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman: - A fix for undetected data corruption on Power9 Nimbus <= DD2.1 in the emulation of VSX loads. The affected CPUs were not widely available. - Two fixes for machine check handling in guests under PowerVM. - A fix for our recent changes to SMP setup, when CONFIG_CPUMASK_OFFSTACK=y. - Three fixes for races in the handling of some of our powernv sysfs attributes. - One change to remove TM from the set of Power10 CPU features. - A couple of other minor fixes. Thanks to: Aneesh Kumar K.V, Christophe Leroy, Ganesh Goudar, Jordan Niethe, Mahesh Salgaonkar, Michael Neuling, Oliver O'Halloran, Qian Cai, Srikar Dronamraju, Vasant Hegde. * tag 'powerpc-5.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/pseries: Avoid using addr_to_pfn in real mode powerpc/uaccess: Don't use "m<>" constraint with GCC 4.9 powerpc/eeh: Fix eeh_dev_check_failure() for PE#0 powerpc/64s: Remove TM from Power10 features selftests/powerpc: Make alignment handler test P9N DD2.1 vector CI load workaround powerpc: Fix undetected data corruption with P9N DD2.1 VSX CI load emulation powerpc/powernv/dump: Handle multiple writes to ack attribute powerpc/powernv/dump: Fix race while processing OPAL dump powerpc/smp: Use GFP_ATOMIC while allocating tmp mask powerpc/smp: Remove unnecessary variable powerpc/mce: Avoid nmi_enter/exit in real mode on pseries hash powerpc/opal_elog: Handle multiple writes to ack attribute
