All Arch: remove linkage for sys_nfsservctl system call

2011-08-26T22:09:58+00:00

The nfsservctl system call is now gone, so we should remove all
linkage for it.

m68k, exec: remove redundant set_fs(USER_DS)

2011-07-26T03:57:12+00:00

The address limit is already set in flush_old_exec() so those calls to
set_fs(USER_DS) are redundant.

m68k: Revive reporting of spurious interrupts

2011-07-25T01:20:41+00:00

commit 2502b667ea835ee16685c74b2a0d89ba8afe117a ("Change the m68knommu irq
handling to use the generic irq framework.") removed the reporting of spurious
interrupts on nommu (68328 and 68360).

Bring it back in a generic way, using "atomic_t irq_err_count", as that's what
most of the other architectures are using.

m68knommu: correctly use trap_init

2011-07-25T01:20:41+00:00

Currently trap_init() is an empty function for m68knommu. Instead
the vectors are being setup as part of the IRQ initialization.
This is inconsistent with m68k and other architectures.

Change the local init_vectors() to be trap_init(), and init the
vectors at the correct time during startup. This will help merge of
m68k and m68knommu trap code in the furture.

m68k: merge the non-mmu and mmu versions of module.c

2011-07-25T01:20:40+00:00

The non-mmu and mmu versions of the module loader module.c are
nearly identical. Merge them back to a single module.c. There is
a little bit of re-ordering of the struct and enum definitions in
module.h to keep the ifdefery to a minimum.

modules: make arch's use default loader hooks

2011-07-24T12:36:04+00:00

This patch removes all the module loader hook implementations in the
architecture specific code where the functionality is the same as that
now provided by the recently added default hooks.

m68k: use kernel processor defines for conditional optimizations

2011-06-14T01:42:29+00:00

Older m68k-linux compilers will include pre-defined symbols that
confuse what processor it is being targeted for. For example gcc-4.1.2
will pre-define __mc68020__ even if you specify the target processor
as -m68000 on the gcc command line. Newer versions of gcc have this
corrected.

In a few places the m68k code uses defined(__mc68020__) for optimizations
that include instructions that are specific to the CPU 68020 and above.
When compiling with older compilers this will be true even when we have
selected to compile for the older 68000 processors.

Switch to using the kernel processor defines, CONFIG_M68020 and friends.
