ARM: 8716/1: pass endianness info to sparse

2017-11-01T19:14:49+00:00

ARM depends on the macros '__ARMEL__' & '__ARMEB__' being defined
or not to correctly select or define endian-specific macros,
structures or pieces of code.

These macros are predefined by the compiler but sparse knows
nothing about them and thus may pre-process files differently
from what gcc would.

Fix this by passing '-D__ARMEL__' or '-D__ARMEB__' to sparse,
depending on the endianness of the kernel, like defined by GCC.

Note: In most case it won't change anything since most ARMs use
      little-endian (but an allyesconfig would use big-endian!).

ARM: 8701/1: fix sparse flags for build on 64bit machines

2017-10-12T10:18:19+00:00

By default sparse uses the characteristics of the build
machine to infer things like the wordsize.
This is fine when doing native builds but for ARM it's,
I suspect, very rarely the case and if the build are done
on a 64bit machine we get a bunch of warnings like:
  'cast truncates bits from constant value (... becomes ...)'

Fix this by adding the -m32 flags for sparse.

arm: Use full path in KBUILD_IMAGE definition

2017-03-20T13:42:20+00:00

The KBUILD_IMAGE variable is used by the rpm and deb-pkg targets, which
expect it to point to the image file in the build directory. The
builddeb script has a workaround for architectures which only provide
the basename, but let's provide a clean interface for packaging tools.

ARM: convert to generated system call tables

2016-10-18T20:34:06+00:00

Convert ARM to use a similar mechanism to x86 to generate the unistd.h
system call numbers and the various kernel system call tables.  This
means that rather than having to edit three places (asm/unistd.h for
the total number of system calls, uapi/asm/unistd.h for the system call
numbers, and arch/arm/kernel/calls.S for the call table) we have only
one place to edit, making the process much more simple.

The scripts have knowledge of the table padding requirements, so there's
no need to worry about __NR_syscalls not fitting within the immediate
constant field of ALU instructions anymore.

ARM: remove indirection of asm/mach-types.h

2016-10-18T19:18:08+00:00

Arrange for mach-types.h to be directly generated in the relevant
path, so we don't need a one-liner file in arch/arm/include/asm/.

ARM: 8588/1: localise objcopy flags

2016-08-12T15:47:01+00:00

We currently define OBJCOPYFLAGS in the top-level arm Makefile, and thus
these flags will be passed to all uses of objcopy, kernel-wide, for
which they are not explicitly overridden. The flags we set are intended
for converting a few ELF files into raw binaries, and thus the flags
chosen are problematic for some other uses which do not expect a raw
binary result, e.g. the upcoming lkdtm rodata test:

  http://www.openwall.com/lists/kernel-hardening/2016/06/08/2

This patch localises the objcopy flags such that they are only used for
the cases we require them for today.
