6f34152f54 x86, boot: Move intcall() to the .inittext section
The .inittext section tries to aggregate all functions which are
needed to get a message out in the case of a load failure.  However,
putchar() uses intcall(), so intcall() should be in the .inittext
section.

e24df921af x86, boot: Use .code16 instead of .code16gcc
This reverts commit 28b48688 ("x86, boot: use .code16gcc instead
of .code16").

Versions of binutils older than 2.16 are already not working, so this
workaround is no longer necessary either.  At the same time, some of
the transformations that .code16gcc does can be *extremely*
counterintuitive to a human programmer.

[ hpa: folded ret -> retl and call -> calll fixes from followup patch ]

28b4868820 x86, boot: use .code16gcc instead of .code16
Use .code16gcc to compile arch/x86/boot/bioscall.S rather than
.code16, since some older versions of binutils can't generate 32-bit
addressing expressions (67 prefixes) in .code16 mode, only in
.code16gcc mode.

cf9972a921 x86, setup: fix comment in the "glove box" code
Impact: Comment change only

The glove box is about avoiding problems with *registers* being
touched, not *memory*.

7a734e7dd9 x86, setup: "glove box" BIOS calls -- infrastructure
Impact: new interfaces (not yet used)

For all the platforms out there, there is an infinite number of buggy
BIOSes.  This adds infrastructure to treat BIOS interrupts more like
toxic waste and "glove box" them -- we switch out the register set,
perform the BIOS interrupt, and then restore the previous state.
