Atmosphere/fusee/fusee-secondary/src/kernel_patches.c
Michael Scire 28717bfd27 fusee/pm: on 5.0.0+, fix system memory pool increase.
Previously, we were only setting resource limit,
which didn't modify actual reserved pool size for
the system pool. This adds kernel patches which reduce
the applet pool size, granting the extra memory to
the system partition. The given value has been chosen
specifically to allow normal applet usages. Further
reduction may result in crashes during normal applet usage.
