108 supply some command-line options at build time by entering them
133 aspects of kernel memory management.
141 bool "High memory support"
146 space as well as some memory mapped IO. That means that, if you
147 have a large amount of physical memory and/or IO, not all of the
148 memory can be "permanently mapped" by the kernel. The physical
149 memory that is not permanently mapped is called "high memory".
154 bool "Set maximum low memory"
157 This option allows you to set the maximum amount of memory which
158 will be used as "low memory", that is, memory which the kernel can
161 memory.
166 hex "Maximum low memory size (in bytes)" if LOWMEM_SIZE_BOOL
176 If non-zero, a jump instruction to this address, will be written
185 the kernel will map low memory (the kernel image will be linked at
186 this address). This can be useful in optimizing the virtual memory
201 virtual memory layout of the system.
