Pull m68nommu updates from Greg Ungerer: "A series of cleanups for the FLAT format binary loader, binfmt_flat, from Christoph. The end goal is to support no-MMU on RISC-V, and the last patch enables that" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu: riscv: add binfmt_flat support binfmt_flat: don't offset the data start binfmt_flat: move the MAX_SHARED_LIBS definition to binfmt_flat.c binfmt_flat: remove the persistent argument from flat_get_addr_from_rp binfmt_flat: provide an asm-generic/flat.h binfmt_flat: make support for old format binaries optional binfmt_flat: add a ARCH_HAS_BINFMT_FLAT option binfmt_flat: add endianess annotations binfmt_flat: use fixed size type for the on-disk format binfmt_flat: consolidate two version of flat_v2_reloc_t binfmt_flat: remove the unused OLD_FLAT_FLAG_RAM definition binfmt_flat: remove the uapi <linux/flat.h> header binfmt_flat: replace flat_argvp_envp_on_stack with a Kconfig variable binfmt_flat: remove flat_old_ram_flag binfmt_flat: provide a default version of flat_get_relocate_addr binfmt_flat: remove flat_set_persistent binfmt_flat: remove flat_reloc_valid

help
|
|
The C6X function call instruction has a limited range of +/- 2MiB.
|
|
This is sufficient for most kernels, but some kernel configurations
|
|
with lots of compiled-in functionality may require a larger range
|
|
for function calls. Use this option to have the compiler generate
|
|
function calls with 32-bit range. This will make the kernel both
|
|
larger and slower.
|
|
|
|
If unsure, say N.

On some architectures there is currently no way for the boot loader

to pass arguments to the kernel. For these architectures, you should

supply some command-line options at build time by entering them

here.

help

Say Y if you plan on running a kernel in big-endian mode.
|
|
Note that your board must be properly built and your board
|
|
port must properly enable any big-endian related features
|
|
of your chipset/board/processor.

config FORCE_MAX_ZONEORDER

int "Maximum zone order"

default "13"
|
|
help
|
|
The kernel memory allocator divides physically contiguous memory
|
|
blocks into "zones", where each zone is a power of two number of
|
|
pages. This option selects the largest power of two that the kernel
|
|
keeps in the memory allocator. If you need to allocate very large
|
|
blocks of physically contiguous memory, then you may need to
|
|
increase this value.
|
|
|
|
This config option is actually maximum order plus one. For example,
|
|
a value of 11 means that the largest free memory block is 2^10 pages.
