kbuild: do not add $(bounds-file) and $(offsets-file) to targets

2015-04-02T14:33:27+00:00

$(always) is added to targets by scripts/Makefile.build.
Moreover, filechk does not need .*.cmd files.

Adding these two files to targets is redundant.

kbuild: Don't reset timestamps in include/generated if not needed

2015-03-24T16:37:25+00:00

Use filechk to generate asm-offsets.h and bounds.h. Based on a patch by
Valdis Kletnieks.

kbuild: remove redundant line from bounds.h/asm-offsets.h

2015-01-05T09:40:09+00:00

This line produces an extra comment line for bounds.h and
asm-offsets.h.

kbuild: merge bounds.h and asm-offsets.h rules

2015-01-05T09:40:09+00:00

The rules "cmd_bounds" and "cmd_offsets" are almost the same.
(The difference is only the include guards.)  They can be merged.

	x86, asm: Fix CFI macro invocations to deal with shortcomings in gas

This breaks MN10300 arch as this changes many instances of instructions
similar to the following:

	MOV	number,D0

which represents an immediate value load into:

	MOV	(number),D0

which the assembler then interprets as a load from absolute address.

x86, asm: Fix ancient-GAS workaround

2010-10-22T08:45:02+00:00

It turns out to generate something like this:

    printk ( ("<3>") "something");

The extra parentheses here break the UML compile.

Change the sed-program to add the parentheses only for numbers.

x86, asm: Fix CFI macro invocations to deal with shortcomings in gas

2010-10-19T21:28:02+00:00

gas prior to (perhaps) 2.16.90 has problems with passing non-
parenthesized expressions containing spaces to macros. Spaces, however,
get inserted by cpp between any macro expanding to a number and a
subsequent + or -. For the +, current x86 gas then removes the space
again (future gas may not do so), but for the - the space gets retained
and is then considered a separator between macro arguments.

Fix the respective definitions for both the - and + cases, so that they
neither contain spaces nor make cpp insert any (the latter by adding
seemingly redundant parentheses).
