[PATCHv10 1/3] powerpc/kernel: Remove check on paca_ptrs_size
From: Pingfan Liu <hidden>
Date: 2023-12-27 02:41:34
Also in:
kexec
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Michael Ellerman, Linus Torvalds
From: Pingfan Liu <redacted> Between early_setup()->allocate_paca_ptrs() and smp_setup_cpu_maps()->free_unused_pacas(), there is no call to set_nr_cpu_ids(), which means nr_cpu_ids is unchanged. Hence removing the check.
