Pull locking updates from Ingo Molnar:
"Here are the locking changes in this cycle:
- rwsem unification and simpler micro-optimizations to prepare for
more intrusive (and more lucrative) scalability improvements in
v5.3 (Waiman Long)
- Lockdep irq state tracking flag usage cleanups (Frederic
Weisbecker)
- static key improvements (Jakub Kicinski, Peter Zijlstra)
- misc updates, cleanups and smaller fixes"

bool "Build a big kernel"
|

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.

default n
|

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.
