Component Type: kbuild config
Description: Maximum number of CPUs (2-32)
More info: MARVEL support can handle a maximum of 32 CPUs, all the others with working support have a maximum of 4 CPUs.

Component Type: kbuild config
Description: Maximum number of CPUs (2-4096)
More info: You should set this to the number of CPUs in your system, but keep in mind that a kernel compiled for, e.g., 2 CPUs will boot but only use 2 CPUs on a >2 CPU system. Setting this to a value larger than 64 will cause the use of a CPU mask array, causing a small performance hit.

Component Type: kbuild config
Description: Maximum number of CPUs (2-256)
More info: This allows you to specify the maximum number of CPUs which this kernel will support. The maximum supported value is 32 for 32-bit kernel and 64 for 64-bit kernels; the minimum value which makes sense is 1 for Qemu (useful only for kernel debugging purposes) and 2 for all others. This is purely to save memory - each supported CPU adds approximately eight kilobytes to the kernel image. For best performance should round up your number of processors to the next power of two.

Description: Maximum number of CPUs (2-512)
More info: This allows you to specify the maximum number of CPUs which this kernel will support. The maximum supported value is 512 and the minimum value which makes sense is 2. This is purely to save memory - each supported CPU adds approximately sixteen kilobytes to the kernel image.

Description: Maximum number of CPUs
More info: This allows you to specify the maximum number of CPUs which this kernel will support. If CPUMASK_OFFSTACK is enabled, the maximum supported value is 8192, otherwise the maximum value is 512. The minimum value which makes sense is 2. This is purely to save memory: each supported CPU adds about 8KB to the kernel image.
