- It limits the possible size of the SMM handler (and the
number of CPUs supported in a system)
- It's not considered a supported path anymore in newer CPUs.

Intel Turbo Boost is a technology implemented by Intel in certain

operating frequency via dynamic control of the CPU's "clock rate".
It is activated when the operating system requests the highest

This change partially addresses the problem with attempting to
generate coreboot image out of tree. The configuration step fails when
in cheroot, if the destination directory is placed in /tmp.
The problem is that the mconf package tries renaming the temporary
file created in the local directory into the destination config file.
If the destination root and the local directory are located on
different file systems, the rename operation fails.
The proper fix (still upcoming) would be to identify all places where
mconf creates temp files, and make sure that all temp files get
created in the destination tree.
This change modifies just one location, which prevents building out of
tree in the most common case.
Test:
run the following in the coreboot directory in chroot:
(coreboot) cp config.lumpy .config
(coreboot) /bin/rm -rf /tmp/cb
(coreboot) CROSS_COMPILE=i686-pc-linux-gnu- make obj=/tmp/cb oldconfig
(coreboot) CROSS_COMPILE=i686-pc-linux-gnu- make obj=/tmp/cb
Observe the build succeed (it was failing during the config phase

The x86 memcpy() implementation did not mention its implicit output
registers ESI, EDI and ECX which might make this code miscompile when
the compiler uses the value of EDI for the return value *after* the 'rep
movsb' has completed. That would break the API of memcpy as this would
return 'dst+len' instead of 'dst'.
Fix this possible bug by removing the wrong comment and listing all
output registers as such (using dummy stack variables that get optimized
away).
Also the leading 'cld' is superflous as the ABI mandates the direction
flag to be cleared all the time when we're in C (see
<http://gcc.gnu.org/gcc-4.3/changes.html>) and we have no ASM call sites
that might require it to be cleared explicitly (SMM might come to mind,
but it clears the DF itself before passing control to the C part of the
SMI handler).
Last but not least fix the prototype to match the one from <string.h>.

For a hyper-threading processor, enabling cache requires that both the
BSP and AP CPU clear CR0.CD (Cache Disable) bit. For a Cache-As-Ram
implementation, partial multi-processor initialisation precedes
raminit and AP CPUs' 16bit entry must be run from ROM.
The AP CPU can only start execute real-mode code at a 4kB aligned
address below 1MB. The protected mode entry code for AP is identical
with the BSP code, which is already located at the top of bootblock.
This patch takes the simplest approach and aligns the bootblock
16 bit entry at highest possible 4kB boundary below 1MB.
The symbol ap_sipi_vector is tested to match CONFIG_AP_SIPI_VECTOR
used by the CAR code in romstage. Adress is not expected to ever
