Even though we manually set a 4KB max page size in our platform builds for 32-bit, we also have to consider the needs of NDK developers (i.e. those folks making native applications/games/etc.). Some of their build configurations might behave very differently with this change, so my current thinking is that 64KB should **not** be the default for ARM Android targets.


Can you say more about your concern? I was actually thinking the exact opposite -- that the special-case in the Driver to use 4K pages on Android AArch64 could very likely be removed, now that using the default 64k max-page-size will no longer cause the binary size to increase.
