x86: remove -maccumulate-outgoing-args on 32-bit

Contrary to the comment "newer gccs do it by default", newer gcc versions
default to -maccumulate-outgoing-args only with CONFIG_CC_OPTIMIZE_FOR_SIZE=n,
and then only with some CPU settings.

Measured with an i386 defconfig, gcc 4.2.1 and kernel 2.6.23-rc1 ("orig" is
the plain kernel, "changed is with -maccumulate-outgoing-args removed):

$ ls -la vmlinux*
-rwxrwxr-x 1 bunk bunk 6269713 2007-07-24 22:19 vmlinux.changed
-rwxrwxr-x 1 bunk bunk 6425361 2007-07-24 22:19 vmlinux.orig
$ size vmlinux.*
   text    data     bss     dec     hex filename
4493465  504108  614400 5611973  55a1c5 vmlinux.changed
4646160  504108  614400 5764668  57f63c vmlinux.orig
$

That's a 2.5% size increase that does for sure hurt small systems.

If the stack unwinder ever comes back and needs this as indicated in the
comment, adding it to the cflags when the user enabled the unwinder should be
a better option.

x86: clear IO_APIC before enabing apic error vector.

4 socket quad core, 8 socket quad core will do apic ID lifting for BSP.

But io-apic regs for ExtINT still use 0 as dest.

so when we enable apic error vector in BSP, we will get one APIC error.

x86: remove extern declarations for code, data, bss resources

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.

x86: make i8259_64 more _32-like

Howdy! Here's a simple janitorish patch for you:

This patch mainly hinges around two includes and their ramifications:

#include <i8259.h> which provides cached_{slave,master}_mask
#include <io_ports.h> which provides PIC_{MASTER,SLAVE}_{IMR,CMD}

Adding these two includes and using those half dozen or so definitions
removed 140+ lines of diffs between i8259_32.c and i8259_64.c, thus
making it easier for the real substantitive differences between them to
show up, and hopefully therefore making it easier to eventually merge
the two.  All the warnings that checkpatch.pl throws (missing spaces

x86: unify mc146818rtc.h - prepare for sharing rtc code

Unify mc146818rtc.h by adding the rtc_cmos_read/write functions to
time_64.c. This is a preparatory patch to finaly share the rtc code,
which is unsurprisingly similar.

code quality - it's just much easier for us to maintain it if every file
in arch/x86 is supposed to be clean.

NOTE: it is a known problem of lindent that it causes some style damage
of its own, but it's a safe tool (well, except for the gcc array range
initializers extension), so we did the bulk of the changes via lindent,
and did the manual fixups in a followup patch.
