This function can run on systems where physical addresses don't
fit in unsigned long, so make sure to use the macro that contains the
proper cast.

__flush_dcache_icache_phys() requires the ability to access the
memory with the MMU disabled, which means that on a 32-bit system
any memory above 4 GiB is inaccessible. In particular, mpc86xx is
32-bit and can have more than 4 GiB of RAM.

If it's required for that patch, why aren't they part of a patchset

This code can never be executed as it is only built when
CONFIG_PPC_E500MC is unset, but the only CPUs that have CPU_FTR_L2CSR
require CONFIG_PPC_E500MC and do not have the MSR/HID0-based nap
mechanism that this file uses.

Some workloads take a lot of TLB misses despite using traditional
hugepages. Handle these TLB misses in the asm fastpath rather than
going through a bunch of C code. With this patch I measured around a
5x speedup in handling hugepage TLB misses.

Commit bb344ca5b90df6 ("powerpc/mpc85xx: Add ranges to etsec2 nodes")
fixes a bug that was exposed by commit 746c9e9f92dd ("of/base: Fix

Use %pS for actual addresses, otherwise you'll get bad output
on arches like ppc64 where %pF expects a function descriptor. Even on
other architectures, refrain from setting a bad example that people

This name is way too generic (though it's moot since you shouldn't use

No Change-Id, and don't bundle patches meant for my tree in the same
patchset as patches meant for other trees. There's no dependency
between them.
