H. Peter Anvin e6e1ace990 x86 setup: sizeof() is unsigned, unbreak comparisons
We use signed values for limit checking since the values can go
negative under certain circumstances.  However, sizeof() is unsigned
and forces the comparison to be unsigned, so move the comparison into
the heap_free() macros so we can ensure it is a signed comparison.

H. Peter Anvin 6b6815c6d5 x86 setup: handle boot loaders which set up the stack incorrectly
Apparently some specific versions of LILO enter the kernel with a
stack pointer that doesn't match the rest of the segments.  Make our
best attempt at untangling the resulting mess.

H. Peter Anvin fa76dab935 x86: clean up setup.h and the boot code
Make <asm/setup.h> usable by the boot code.

Clean up vestiges of the old command-line protocol from setup.h and
head_32.S (it is still supported from the boot loader point of
view, since it is converted to the new command-line protocol by the
boot code.)
