2009-09-16m68knommu: remove per device interrupt mask setting for ColdFire 520xGreg Ungerer
With general interrupt controller code in place we don't need specific unmasking code for the internal ColdFire 520x UARTs or ethernet (FEC). Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2009-09-16m68knommu: use general interrupt controller for ColdFire 520x familyGreg Ungerer
Create general interrupt controller code for the ColdFire 520x family, that does proper masking and unmasking of interrupts. With this in place some of the driver hacks in place to support ColdFire interrupts can finally go away. Within the ColdFire family there is a variety of different interrupt controllers in use. Some are used on multiple parts, some on only one. There is quite some differences in some varients, so much so that common code for all ColdFire parts would be impossible. This commit introduces code to support one of the newer interrupt controllers in the ColdFire 5208 and 5207 parts. It has very simple mask and unmask operations, so is one of the easiest to support.

2009-07-09linker script: unify usage of discard definitionTejun Heo
Discarded sections in different archs share some commonality but have considerable differences. This led to linker script for each arch implementing its own /DISCARD/ definition, which makes maintaining tedious and adding new entries error-prone. This patch makes all linker scripts to move discard definitions to the end of the linker script and use the common DISCARDS macro. As ld uses the first matching section definition, archs can include default discarded sections by including them earlier in the linker script. ia64 is notable because it first throws away some ia64 specific subsections and then include the rest of the sections into the final image, so those sections must be discarded before the inclusion. defconfig compile tested for x86, x86-64, powerpc, powerpc64, ia64, alpha, sparc, sparc64 and s390. Michal Simek tested microblaze.

2009-06-24linker script: throw away .discard sectionTejun Heo
x86 throws away .discard section but no other archs do. Also, .discard is not thrown away while linking modules. Make every arch and module linking throw it away. This will be used to define dummy variables for percpu declarations and definitions. This patch is based on Ivan Kokshaysky's alpha percpu patch.
