2181 the price of higher memory consumption. This option is available

2207 The kernel memory allocator divides physically contiguous memory
2208 blocks into "zones", where each zone is a power of two number of
2209 pages. This option selects the largest power of two that the kernel
2210 keeps in the memory allocator. If you need to allocate very large
2211 blocks of physically contiguous memory, then you may need to
2212 increase this value.
2213
2214 This config option is actually maximum order plus one. For example,
2215 a value of 11 means that the largest free memory block is 2^10 pages.
2216
2217 The page size is not necessarily 4KB. Keep this in mind
2218 when choosing a value for this option.

2852 kexec is a system call that implements the ability to shutdown your
2853 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02002854 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09002855 you can start any kernel with it, not just Linux.
2856
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02002857 The name comes from the similarity to the exec system call.

2860 is properly shutdown, so do not be surprised if this code does not

2908 When this is enabled, the kernel will support use of 64-bit floating
2909 point registers with binaries using the O32 ABI along with the
2910 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2911 32-bit MIPS systems this support is at the cost of increasing the
2912 size and complexity of the compiled FPU emulator. Thus if you are
2913 running a MIPS32 system and know that none of your userland binaries
2914 will require 64-bit floating point, you may wish to reduce the size
2915 of your kernel & potentially improve FP emulation performance by
2916 saying N here.
