From 51b563fc93c8cb5bff1d67a0a71c374e4a4ea049 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sun, 20 Sep 2009 12:28:22 +0200 Subject: arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0 Albin Tonnerre reported: Bash 4 filters out variables which contain a dot in them. This happends to be the case of CPPFLAGS_vmlinux.lds. This is rather unfortunate, as it now causes build failures when using SHELL=/bin/bash to compile, or when bash happens to be used by make (eg when it's /bin/sh) Remove the common definition of CPPFLAGS_vmlinux.lds by pushing relevant stuff to either Makefile.build or the arch specific kernel/Makefile where we build the linker script. This is also nice cleanup as we move the information out where it is used. Notes for the different architectures touched: arm - we use an already exported symbol cris - we use a config symbol aleady available [Not build tested] mips - the jiffies complexity has moved to vmlinux.lds.S where we need it. Added a few variables to CPPFLAGS - they are only used by the linker script. [Not build tested] powerpc - removed assignment that is not needed [not build tested] sparc - simplified it using $(BITS) um - introduced a few new exported variables to deal with this xtensa - added options to CPP invocation [not build tested] Cc: Albin Tonnerre Cc: Russell King Cc: Mikael Starvik Cc: Jesper Nilsson Cc: Benjamin Herrenschmidt Cc: Paul Mackerras Cc: "David S.
