* doc: Fix comparison operatorOlaf Mandel2014-10-271-1/+1
| | | | | | | | | | | Align the documentation with the include/linux/etherdevice.h , which is where this example comes from. The return value from the check was inverted in the documentation.

* arm: Switch to -mno-unaligned-access when supported by the compilerTom Rini2014-02-261-0/+240
When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.
