[PATCH 0/2] Android: Add support for a 32bit Android file system in a 64bit kernel

From: Serban Constantinescu

Hi all,

The following set of patches will provide support for a 32-bit Android file
system running on top of 64-bit kernel. We have tested them successfully on
64-bit platforms (Real Time Simulation Model ARMv8) as well as on 32-bit ones
(4xA9 Versatile Express). For RTSMv8 we have been using 64-bit kernel build,
running the CPU in the AArch64 state, and an ARMv7 file system build, running
in AArch32 state of ARMv8.

Please take a look and let me know if you have any feedback.

Note: This set of patches will affect only an Android build of the Linux
kernel, the drivers(binder, ashmem) are not pulled in for a default Linux

Best Regards,
