Merge the rest functions together, with proper preprocessing directives.
Finally remove module_{32|64}.c.

x86 module: merge the same functions in module_32.c and module_64.c2009-06-12T12:17:00+00:00Amerigo Wangamwang@redhat.com2009-06-04T01:46:09+00:00urn:sha1:2d5bf28fb9e3c178db4f5536e2fe38d3a5ed7f40
Merge the same functions both in module_32.c and module_64.c into
module.c.
This is the first step to merge both of them finally.

PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architectures2008-07-24T17:47:21+00:00Andrea Righirighi.andrea@gmail.com2008-07-24T04:28:13+00:00urn:sha1:27ac792ca0b0a1e7e65f20342260650516c95864
On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit
boundary. For example:
u64 val = PAGE_ALIGN(size);
always returns a value < 4GB even if size is greater than 4GB.
The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for
example):
#define PAGE_SHIFT 12
#define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT)
#define PAGE_MASK (~(PAGE_SIZE-1))
...
#define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK)
The "~" is performed on a 32-bit value, so everything in "and" with
PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary.
Using the ALIGN() macro seems to be the right way, because it uses
typeof(addr) for the mask.
Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in
include/linux/mm.h.

x86, 64-bit: patch paravirt inline replacements when loading modules2008-06-30T10:12:43+00:00Anders H Kaseorgandersk@MIT.EDU2008-06-28T22:25:41+00:00urn:sha1:5e5a29bf2624a5984e1c36c3a2481ee91249ec9c
small speedup.
Paravirt replacements were added to the i386 module loader by commit
139ec7c416248b9ea227d21839235344edfee1e0. This adds the same code to
the x86_64 module loader.
