* [PATCH] m68knommu: improve syscall entry and fix stracePhilippe De Muyter2006-06-26
| | | | | | | | | | | | Here is a patch to the system call handling for 5307/5272/etc to: - fix the strace support (one tested the wrong bit) - make all system calls a little bit faster by inlining set_esp0 and supporting ENOSYS out of the critical path. - remove extraneous spaces Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] Fix kdump Crash Kernel boot memory reservation for NUMA machinesAmul Shah2006-06-25
| | | | | | | | | | | | | | | | | | | | This patch will fix a boot memory reservation bug that trashes memory on the ES7000 when loading the kdump crash kernel. The code in arch/x86_64/kernel/setup.c to reserve boot memory for the crash kernel uses the non-numa aware "reserve_bootmem" function instead of the NUMA aware "reserve_bootmem_generic". I checked to make sure that no other function was using "reserve_bootmem" and found none, except the ones that had NUMA ifdef'ed out. I have tested this patch only on an ES7000 with NUMA on and off (numa=off) in a single (non-NUMA) and multi-cell (NUMA) configurations.

* [PATCH] Make copy_from_user_inatomic NOT zero the tail on i386NeilBrown2006-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | As described in a previous patch and documented in mm/filemap.h, copy_from_user_inatomic* shouldn't zero out the tail of the buffer after an incomplete copy. This patch implements that change for i386. For the _nocache version, a new __copy_user_intel_nocache is defined similar to copy_user_zeroio_intel_nocache, and this is ultimately used for the copy. For the regular version, __copy_from_user_ll_nozero is defined which uses __copy_user and __copy_user_intel - the later needs casts to reposition the __user annotations. If copy_from_user_atomic is given a constant length of 1, 2, or 4, then we do still zero the destintion on failure. This didn't seem worth the effort of fixing as the places where it is used really don't care.

It is purely code-motion; there should be no functional changes at all. Several functions in arch/i386/kernel/setup.c needed to be made non-static so that they're visible to the code in mach-*/setup.c. asm-i386/setup.h is used to hold the prototypes for these functions.
