One fix for a boot failure on 32-bit, introduced during the merge window. A fix for our handling of CLOCK_MONOTONIC in the 64-bit VDSO. Changing the wall clock across the Y2038 boundary could cause CLOCK_MONOTONIC to jump forward and backward. Our spectre_v2 reporting was a bit confusing due to a bug I introduced. On some systems it was reporting that the count cache was disabled and also that we were flushing the count cache on context switch. Only the former is true, and given that the count cache is disabled it doesn't make any sense to flush it. No one reported it, so presumably the presence of any mitigation is all people check for. Finally a small build fix for zsmalloc on 32-bit. Thanks to: Ben Hutchings, Christophe Leroy, Diana Craciun, Guenter Roeck, Michael Neuling. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJclNlOAAoJEFHr6jzI4aWAzoQQAJ80jKyZj/GSLXKJQpD9p+bO XrbXzFF3tc3ctqKNOULEkUs3XlV3UWbSm7WZBBtruZy34s1r4WLrtk38+/41ZSZA TdUj7/mZEKfi+RzA2o8dsKjRwNHh2atzYwwPY16Czv53LW6zN1xL0+QLZp7/sZsF sy6pAeHiBsvTBrVtldRLmE2nWgaEy9eX2TQ/O9OdU8D0febHF8xSUQQJ9GCS1B8G t3hq+Q1fJQhq/81x2AKtChQyWvw4747K4icXXRE+Fgh12I3STuE3q2iAOYjII2k8 IWhJM5/LR5lwnmubt1ezK/k5iMFaibn4lckEG/q+MR4NN98Z63OHCDoI8dendoif 6Ok+6d4Ven3c5SGhZSXzPsQow7VTewzcCw41BKApuNts4FR0EtQUIAQYDvqO39d3 OST9bPuTtNA48Jfjsy07VmBS8LfuMHmnrtRT6xUW0f/2Bt1r4JY6SX9F+HvN8JTU KdalG1t4R/sXVJNd/mflF/IhP3xw9Cz75DojvZ6M7GjI+Y9Tg9jsRXu0MdhM4XxS fPpQlsOCBJnX5OrRMNbXAZCR/KLeW14V9143OAwsj3h3gLy5QC8kUHp9tEx8ZbM3 eE425B7DMDnB+w6URc0VQHB2E+wbSc+gtLHBOqmdRfjVy0IjtPI2taZMQiXNBNNN V554zrEyJPnxRiZhedrG =NixN -----END PGP SIGNATURE----- Merge tag 'powerpc-5.1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: "One fix for a boot failure on 32-bit, introduced during the merge window.
