2013-01-30MIPS: AR71xx: Fix AR71XX_PCI_MEM_SIZEGabor Juhos
The base address of the PCI memory is 0x10000000 and the base address of the PCI configuration space is 0x17000000 on the AR71xx SoCs. The AR71XX_PCI_MEM_SIZE is defined as 0x08000000 which is wrong because that overlaps with the configuration space. This patch fixes the value of the AR71XX_PCI_MEM_SIZE constant, in order to avoid this resource conflicts.

2013-01-29x86: Don't panic if can not alloc buffer for swiotlbYinghai Lu
Normal boot path on system with iommu support: swiotlb buffer will be allocated early at first and then try to initialize iommu, if iommu for intel or AMD could setup properly, swiotlb buffer will be freed. The early allocating is with bootmem, and could panic when we try to use kdump with buffer above 4G only, or with memmap to limit mem under 4G. for example: memmap=4095M$1M to remove memory under 4G. According to Eric, add _nopanic version and no_iotlb_memory to fail map single later if swiotlb is still needed. -v2: don't pass nopanic, and use -ENOMEM return value according to Eric. panic early instead of using swiotlb_full to panic...according to Eric/Konrad. -v3: make swiotlb_init to be notpanic, but will affect: arm64, ia64, powerpc, tile, unicore32, x86. -v4: cleanup swiotlb_init by removing swiotlb_init_with_default_size.

2013-01-17sk-filter: Add ability to lock a socket filter programVincent Bernat
While a privileged program can open a raw socket, attach some restrictive filter and drop its privileges (or send the socket to an unprivileged program through some Unix socket), the filter can still be removed or modified by the unprivileged program. This commit adds a socket option to lock the filter (SO_LOCK_FILTER) preventing any modification of a socket filter program. This is similar to OpenBSD BIOCLOCK ioctl on bpf sockets, except even root is not allowed change/drop the filter. The state of the lock can be read with getsockopt(). No error is triggered if the state is not changed. -EPERM is returned when a user tries to remove the lock or to change/remove the filter while the lock is active. The check is done directly in sk_attach_filter() and sk_detach_filter() and does not affect only setsockopt() syscall. Signed-off-by: Vincent Bernat <bernat@luffy.cx> Signed-off-by: David S.

Besides that there are updates to the AMD IOMMU driver for refactor the IOMMU-Groups support and to make sure it does not trigger a hardware erratum. The OMAP changes (for which I pulled in a branch from Tony Lindgren's tree) have a conflict in linux-next with the arm-soc tree.
