Now all the platforms enable ARCH_HAS_GET_PAGE_PROT. They define and export own vm_get_page_prot() whether custom or standard DECLARE_VM_GET_PAGE_PROT. Hence there is no need for default generic fallback for vm_get_page_prot(). Just drop this fallback and also ARCH_HAS_GET_PAGE_PROT mechanism.

On some platforms, there is currently no way for the boot loader
|
|
to pass arguments to the kernel. For these, you should supply some
|
|
command-line options at build time by entering them here. At a
|
|
minimum, you should specify the memory size and the root device
|
|
(e.g., mem=64M root=/dev/nfs).

This allows you to specify the maximum number of CPUs which this

|
kernel will support. The maximum supported value is 6 and the
|
|
minimum value which makes sense is 2.
|
|
|
|
This is purely to save memory - each supported CPU adds
|
|
approximately eight kilobytes to the kernel image.
