lib/int_sqrt.c: optimize square root algorithm

Optimize the current version of the shift-and-subtract (hardware)
algorithm, described by John von Newmann[1] and Guy L Steele.

Iterating 1,000,000 times, perf shows for the current version:

lib/memcopy: use glibc version

the kernel's memcpy and memmove is very inefficient. But the glibc version is
quite fast, in some cases it is 10 times faster than the kernel version. So I
introduce some memory copy macros and functions of the glibc to improve the
kernel version's performance.

The strategy of the memory functions is:
1. Copy bytes until the destination pointer is aligned.
2. Copy words in unrolled loops.  If the source and destination are not
   aligned in the same way, use word memory operations, but shift and merge
   two read words before writing.
3. Copy the few remaining bytes.

usb: gadget: mass_storage: added sysfs entry for cdrom to LUNs

This patch adds a "cdrom" sysfs entry for each mass_storage LUN, just
like "ro" sysfs entry. This allows switching between USB and CD-ROM
emulation without reinserting the module or recompiling the kernel.

DRIVERS: SLIMBUS: initial overclocking of slimbus .Increase root freq from 11 (24.526MHz) to 31 max (27+MHz) which is the largest it will take .Increase clock gear from 7 to 10 (max again)

This means SLIMbus will use its maximum potential to give the best audio quality for the hardware. Takes advantage of both hardware and the mods from zeroinfinity, also opening the door for more things that were previously limited by this. Researched and experimented by ZeroInfinity and Poondog
