2008-01-30x86: irqflags consolidationGlauber de Oliveira Costa
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.

2008-01-30x86: clean up nmi_32/64.cHiroshi Shimamoto
clean up and make nmi_32/64.c more similar. - white space and coding style clean up. - nmi_cpu_busy is available on CONFIG_SMP. - move functions __acpi_nmi_enable, acpi_nmi_enable, __acpi_nmi_disable and acpi_nmi_disable. - make variables name more similar.

2008-01-30x86: remove extern declarations for code, data, bss resourcesBernhard Walle
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.

2008-01-30x86: mtrr use type bool [RESEND AGAIN]Paul Jimenez
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.

2008-01-30x86: make i8259_64 more _32-likePaul Jimenez
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 after commas and >80 character lines) exist intentionally to match i8259_32.c.
