From: Tom Musta <tommu...@gmail.com> This patch series addresses bugs in the PowerPC single-step emulation code (arch/powerpc/lib/sstep.c) pertaining to Little Endian.
The existing code has a chicken switch for little endian. The first patch softens the restriction so that only cross-endian modes are not supported. There is a general problem with unaligned little endian loads and stores. This is addressed by the second patch. Finally, there is a problem with unaligned single precision floating point loads and stores which is addressed by the third patch. V2: fixed bug in MSR[LE] check identified by Andreas Schwab and Geert Uytterhoeven.
