Pull OLPC platform updates from Andres Salomon: "These move the OLPC Embedded Controller driver out of arch/x86/platform and into drivers/platform/olpc. OLPC machines are now ARM-based (which means lots of x86 and ARM changes), but are typically pretty self-contained.. so it makes more sense to go through a separate OLPC tree after getting the appropriate review/ACKs." * 'for-linus-3.6' of git://dev.laptop.org/users/dilinger/linux-olpc: x86: OLPC: move s/r-related EC cmds to EC driver Platform: OLPC: move global variables into priv struct Platform: OLPC: move debugfs support from x86 EC driver x86: OLPC: switch over to using new EC driver on x86 Platform: OLPC: add a suspended flag to the EC driver Platform: OLPC: turn EC driver into a platform_driver Platform: OLPC: allow EC cmd to be overridden, and create a workqueue to call it drivers: OLPC: update various drivers to include olpc-ec.h Platform: OLPC: add a stub to drivers/platform/ for the OLPC EC driver

2012-08-01netvm: propagate page->pfmemalloc from skb_alloc_page to skbMel Gorman
The skb->pfmemalloc flag gets set to true iff during the slab allocation of data in __alloc_skb that the the PFMEMALLOC reserves were used. If page splitting is used, it is possible that pages will be allocated from the PFMEMALLOC reserve without propagating this information to the skb. This patch propagates page->pfmemalloc from pages allocated for fragments to the skb. It works by reintroducing and expanding the skb_alloc_page() API to take an skb. If the page was allocated from pfmemalloc reserves, it is automatically copied. If the driver allocates the page before the skb, it should call skb_propagate_pfmemalloc() after the skb is allocated to ensure the flag is copied properly. Failure to do so is not critical. The resulting driver may perform slower if it is used for swap-over-NBD or swap-over-NFS but it should not result in failure.

2012-07-25mlx4: Add support for EEH error recoveryKleber Sacilotto de Souza
Currently the mlx4 drivers don't have the necessary callbacks to implement EEH errors detection and recovery, so the PCI layer uses the probe and remove callbacks to try to recover the device after an error on the bus. However, these callbacks have race conditions with the internal catastrophic error recovery functions, which will also detect the error and this can cause the system to crash if both EEH and catas functions try to reset the device. This patch adds the necessary error recovery callbacks and makes sure that the internal catastrophic error functions will not try to reset the device in such scenarios. It also adds some calls to pci_channel_offline() to suppress reads/writes on the bus when the slot cannot accept I/O operations so we prevent unnecessary accesses to the bus and speed up the device removal.
