2011-07-18xen/multicalls: disable MC_DEBUGJeremy Fitzhardinge
It's useful - and probably should be a config - but its very heavyweight, especially with the tracing stuff to help sort out problems. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
2011-07-18xen/mmu: tune pgtable alloc/releaseJeremy Fitzhardinge
Make sure the fastpath code is inlined. Batch the page permission change and the pin/unpin, and make sure that it can be batched with any adjacent set_pte/pmd/etc operations. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

2011-07-18ARM: change ARM_DMA_ZONE_SIZE into a variableNicolas Pitre
Having this value defined at compile time prevents multiple machines with conflicting definitions to coexist. Move it to a variable in preparation for having a per machine value selected at run time. This is relevant only when CONFIG_ZONE_DMA is selected. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>

2011-07-18ARM: mach-loki: deleteNicolas Pitre
This was introduced more than 3 years ago, and since then only generic janitorial changes were made without further addition of actual support for "real" devices. This is therefore a cost with no benefits to keep in the tree. If someone wishes to revive this code, it is always possible to retrieve it from the Git repository.

Commit bcae8aeb32 "[ARM] S3C24A0: Initial architecture support files" brought in a bunch of files while explicitly leaving out the corresponding Kconfig entry, stating that the series is not complete. More than 2.5 years later, the support for this has not seen any progress. This is therefore dead code.

2011-07-16PM / MIPS: Convert i8259.c to using syscore_opsRafael J. Wysocki
The code in arch/mips/kernel/i8259.c still hasn't been converted to using struct syscore_ops instead of a sysdev for resume and shutdown. As a result, this code doesn't build any more after suspend, resume and shutdown callbacks have been removed from struct sysdev_class. Fix this problem by converting i8259.c to using syscore_ops.

2011-07-15nfsd: Remove deprecated nfsctl system call and related code.NeilBrown
As promised in feature-removal-schedule.txt it is time to remove the nfsctl system call. Userspace has perferred to not use this call throughout 2.6 and it has been excluded in the default configuration since 2.6.36 (9 months ago). So this patch removes all the code that was being compiled out. There are still references to sys_nfsctl in various arch systemcall tables and related code. These should be cleaned out too, probably in the next merge window. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
