Whitespace issues aside, I have applied the patch on top of kernel 6.1.55 and tested on both a dual-socket Ampere Altra machine with < 256 CPUs, and a dual-socket AmpereOne machine with > 256 CPUs. Works as expected, with all CPUs visible and functional. > config NR_CPUS > int "Maximum number of CPUs (2-4096)" > range 2 4096 > - default "256" > + default 512 Nit: the new default value should be in quotation marks, if we want to be pedantic Tested-by: Eric Mackay <eric.mackay@xxxxxxxxxx>
