The cli and sti instructions need to be replaced by paravirt hooks.
For the i386 architecture, this is already done. The code requirements
aren't much different from x86_64 POV, so this part is consolidated in
the common header

This patch consolidates the irqflags include files containing common
paravirt definitions. The native definition for interrupt handling, halt,
and such, are the same for 32 and 64 bit, and they are kept in irqflags.h.
the differences are split in the arch-specific files.
The syscall function, irq_enable_sysexit, has a very specific i386 naming,
and its name is then changed to a more general one.

This patch removes the extern struct resource declarations for
data_resource, code_resource and bss_resource on x86 and declares that
three structures as static as done on other architectures like IA64.
On i386, these structures are moved to setup_32.c (from e820_32.c) because
that's code that is not specific to e820 and also required on EFI systems.
That makes the "extern" reference superfluous.
On x86_64, data_resource, code_resource and bss_resource are passed to
e820_reserve_resources() as arguments just as done on i386 and IA64. That
also avoids the "extern" reference and it's possible to make it static.

This is a janitorish patch to 1) remove private TRUE/FALSE #def's in
favor of using the standard enum from linux/stddef.h and 2) switch the
variables holding those values to type 'bool' (from linux/types.h)
since it both seems more appropriate and allows for potentially better
optimization.
As a truly minor aside, I removed a couple of comments documenting
a 'do_safe' parameter that seems to no longer exist.

Prepare for merging <asm/alternative_{32,64}.h> by making the 32- and
64-bit versions textually identical. This involves:
- removing arbitrary header inclusion differences
- reorganizing the 32-bit version slightly to match the 64-bit version
- using <asm/asm.h> to unify the assembly code
- renaming struct paravirt_patch to struct paravirt_patch_site in the
64-bit version to match the 32-bit version; there are no references
to struct paravirt_patch elsewhere in the tree.
