[PATCH] x86/boot: v4.4 stable and v4.9 stable boot failure due to dropped patch line

by John S Gruber

This regards upstream commit a90118c445cc ("x86/boot: Save fields explicitly, zero out everything else") application to linux-stable. Its corresponding commits to the stable 4.4 and 4.9 trees didn't apply correctly, probably due to a field name change (e820_table had been named e820_map before 4.10). On my desktop I'm unable to boot a signed kernel due to these commits. Add e820_map (to replace e820_table) to the preserved fields so that the E820 memory regions in boot_params can be accessed by the kernel after boot_params has been sanitized. Signed-off-by: John S Gruber <JohnSGruber(a)gmail.com> Fixes: 41664b97f46e ("x86/boot: Save fields explicitly, zero out everything else") Fixes: 4e478cb2ccdd ("x86/boot: Save fields explicitly, zero out everything else") Link: https://lore.kernel.org/lkml/20190731054627.5627-2-jhubbard@nvidia.com/ --- I tested stable 4.14.145, 4.19.74, and 5.2.16 successfully under the same circumstances.

[tip: perf/urgent] perf stat: Reset previous counts on repeat with interval

The wrong values will be shown for the first interval on the second and subsequent repetitions. Without the fix: # perf stat -r 3 -I 2000 -e faults -e sched:sched_switch -a sleep 5 2.000282489 53 faults 2.000282489 513 sched:sched_switch 4.005478208 3,721 faults 4.005478208 2,666 sched:sched_switch 5.025470933 395 faults 5.025470933 1,307 sched:sched_switch 2.009602825 1,84,46,74,40,73,70,95,47,520 faults <------ 2.009602825 1,84,46,74,40,73,70,95,49,568 sched:sched_switch <------ 4.019612206 4,730 faults 4.019612206 2,746 sched:sched_switch 5.039615484 3,953 faults 5.039615484 1,496 sched:sched_switch 2.000274620 1,84,46,74,40,73,70,95,47,520 faults <------ 2.000274620 1,84,46,74,40,73,70,95,47,520 sched:sched_switch <------ 4.000480342 4,282 faults 4.000480342 2,303 sched:sched_switch 5.000916811 1,322 faults 5.000916811 1,064 sched:sched_switch # prev_raw_counts is allocated when using intervals. This is used when calculating the difference in the counts of events when using interval. The current counts are stored in prev_raw_counts to calculate the differences in the next iteration. On the first interval of the second and subsequent repetitions, prev_raw_counts would be the values stored in the last interval of the previous repetitions, while the current counts will only be for the first interval of the current repetition. Hence there is a possibility of events showing up as big number. Fix this by resetting prev_raw_counts whenever perf stat repeats the command.

[tip: perf/urgent] perf stat: Fix a segmentation fault when using repeat forever

by tip-bot2 for Srikar Dronamraju

Without fix: # perf stat -r 0 -I 5000 -e cycles -a sleep 10 # time counts unit events 5.000211692 3,13,89,82,34,157 cycles 10.000380119 1,53,98,52,22,294 cycles 10.040467280 17,16,79,265 cycles Segmentation fault This problem was only observed when we use forever option aka -r 0 and works with limited repeats. Calling print_counter with ts being set to NULL, is not a correct option when interval is set. Hence avoid print_counter(NULL,..) if interval is set.
