Subject: powerpc: Do not reload on CPU hot removal
|
|
References: bsc#1133407, LTC#176111
|
|
Git-commit: d1c4f630f0da0bf43928e3c975f02e832b2df50f
|
|
|
|
Skipping reload after a CPU goes offline does not have any adverse
|
|
impact, as /sys/devices/system/cpu/cpuX nodes are present for all
|
|
"possible" CPUs on PPC64.
|
|
|
|
The udev rule for CPU online operation is still needed. If reload
|
|
is skipped and the system crashes on a hot-added CPU, the kdump
|
|
kernel fails to get the 'boot_cpuid' after a hot plug and
|
|
eventually fails (see early_init_dt_scan_cpus() in
|
|
arch/powerpc/kernel/prom.c file).
