2006-09-26[PATCH] x86: add a bootparameter to reserve high linear address spaceZachary Amsden
Add a boot parameter to reserve high linear address space for hypervisors. This is necessary to allow dynamically loaded hypervisor modules, which might not happen until userspace is already running, and also provides a useful tool to benchmark the performance impact of reduced lowmem address space.

2006-09-26[PATCH] zone_reclaim: dynamic slab reclaimChristoph Lameter
Currently one can enable slab reclaim by setting an explicit option in /proc/sys/vm/zone_reclaim_mode. Slab reclaim is then used as a final option if the freeing of unmapped file backed pages is not enough to free enough pages to allow a local allocation. However, that means that the slab can grow excessively and that most memory of a node may be used by slabs. We have had a case where a machine with 46GB of memory was using 40-42GB for slab. Zone reclaim was effective in dealing with pagecache pages. However, slab reclaim was only done during global reclaim (which is a bit rare on NUMA systems). This patch implements slab reclaim during zone reclaim. Zone reclaim occurs if there is a danger of an off node allocation. At that point we 1. Shrink the per node page cache if the number of pagecache pages is more than min_unmapped_ratio percent of pages in a zone. 2. Shrink the slab cache if the number of the nodes reclaimable slab pages (patch depends on earlier one that implements that counter) are more than min_slab_ratio (a new /proc/sys/vm tunable). The shrinking of the slab cache is a bit problematic since it is not node specific. So we simply calculate what point in the slab we want to reach (current per node slab use minus the number of pages that neeed to be allocated) and then repeately run the global reclaim until that is unsuccessful or we have reached the limit. I hope we will have zone based slab reclaim at some point which will make that easier. The default for the min_slab_ratio is 5% Also remove the slab option from /proc/sys/vm/zone_reclaim_mode.

2006-09-26[PATCH] x86: Allow disabling early pci scans with pci=noearly or disallowing ↵Andi Kleen
conf1 Some buggy systems can machine check when config space accesses happen for some non existent devices. i386/x86-64 do some early device scans that might trigger this. Allow pci=noearly to disable this. Also when type 1 is disabling also don't do any early accesses which are always type1. This moves the pci= configuration parsing to be a early parameter. I don't think this can break anything because it only changes a single global that is only used by PCI.

This is useful to prevent compilation errors when users select CONFIG_STACK_UNWIND on old binutils and also allows to use CFI in the future for non kernel debugging applications.

Adds a new /proc/sys/kernel/nmi_watchdog call that will enable/disable the nmi watchdog. By entering a non-zero value here, a user can enable the nmi watchdog to monitor the online cpus in the system. By entering a zero value here, a user can disable the nmi watchdog and free up a performance counter which could then be utilized by the oprofile subsystem, otherwise oprofile may be short a counter when in use.

2006-09-25[PATCH] bonding: Validate probe replies in ARP monitorJay Vosburgh
Add logic to check ARP request / reply packets used for ARP monitor link integrity checking. The current method simply examines the slave device to see if it has sent and received traffic; this can be fooled by extraneous traffic. For example, if multiple hosts running bonding are behind a common switch, the probe traffic from the multiple instances of bonding will update the tx/rx times on each other's slave devices.
