Blackfin arch: make sure cycles is marked as volatile so gcc doesnt reorder on us
Blackfin arch: disable CONFIG_HW_RANDOM and CONFIG_DAB in defconfig files
Blackfin arch: update cache flush prototypes with argument names to make them less mysterious
Blackfin arch: move bfin_addr_dcachable() and friends into the cacheflush header where it belongs
Blackfin arch: use the new bfin_addr_dcachable() function
Blackfin arch: fix bug - build kernel failed at head.S when reprogram clock on all platforms
Blackfin arch: unify/cleanup cache code
Blackfin arch: update AD7879 platform resources in board file
Blackfin arch: Zero out bss region in L1/L2 memory.
Blackfin arch: add read/write IO accessor functions to Blackfin
Blackfin arch: fix bug - some serial header files set RTS to an input when they should all be outputs
- to be correct wrt to end ranges
- to be optimal with a one-instruction hardware loop

As policy->governor is already set to CPUFREQ_DEFAULT_GOVERNOR in the
(always built-in) cpufreq core, we do not need to set it in the drivers.
This fixes the sparc64 allmodconfig build failure.
Also, remove a totally useles setting of ->policy in cpufreq-pxa3xx.c.

Using just 'unsigned' will make flags an unsigned int. While this is
arguably not an error on blackfin where sizeof(int) == sizeof(long),
the patch is still justified on the grounds of principle.
The patch was generated using the Coccinelle semantic patch framework.
