* Enter long mode
* Add 64bit entry to GDT
* Use x86_64 SysV ABI calling conventions for C code entry
* Change smm_module_params' cpu to size_t as 'push' is native integer
* Drop to protected mode after c handler
NOTE: This commit does NOT introduce a new security model. It uses the
same page tables as the remaining firmware does.
This can be a security risk if someone is able to manipulate the
page tables stored in ROM at runtime. USE FOR TESTING ONLY!
Tested on Lenovo T410 with additional x86_64 patches.

Unlike Linux kernel which has a static shadow region layout, we have
multiple stages in coreboot and thus require a different shadow offset
address. Unfortunately, GCC currently only supports adding a static
shadow offset at compile time using -fasan-shadow-offset flag.
For this reason, we enable GCC to determine asan shadow offset address
at runtime using a callback function named __asan_shadow_offset().
This supersedes the need to specify this address at compile time. GCC
then makes use of this shadow offset to protect stack buffers by
inserting red zones around them.
Some other benefits of having this GCC patch are:
a. We can place the shadow region in a separate linker section with
all its advantages like automatic fit insurance. This ensures if
a platform doesn't have enough memory space to hold shadow region,
the build will fail. (However, if we use a fixed shadow offset on a
platform that actually doesn't have enough memory, it may still
build without any errors.)
b. We don't modify the memory layout compared to the current one, as
we are placing the shadow region at the end of the space already
occupied by the program.
c. We can be much more flexible later if needed (thinking of other
stages like bootblock).
d. Since we are appending the shadow buffer to the region already
occupied, we make efficient use of the limited memory available
which is highly beneficial when using cache as ram.
Further, we have made sure that if you compile you tree with ASan
enabled but missed this patch, it will end up in the following
compilation error:
"invalid --param name 'asan-use-shadow-offset-callback'"
So, you cannot accidentally enable the feature without having your
compiler patched.
