Because in i386 early boot stage, boot_cpu_data may be not available, which makes clflush_cach_range() into infinite loop, which is called by change_page_attr(). This patch fixes this by setting boot_cpu_data.x86_clflush_size in early_cpu_detect(). Signed-off-by: NHuang Ying <ying.huang@intel.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

This patch adds support for setting up a fixed IOMMU mapping on certain cell machines. For 64-bit devices this avoids the performance overhead of mapping and unmapping pages at runtime. 32-bit devices are unable to use the fixed mapping. The fixed mapping is established at boot, and maps all of physical memory 1:1 into device space at some offset. On machines with < 30 GB of memory we setup the fixed mapping immediately above the normal IOMMU window. For example a machine with 4GB of memory would end up with the normal IOMMU window from 0-2GB and the fixed mapping window from 2GB to 6GB. In this case a 64-bit device wishing to DMA to 1GB would be told to DMA to 3GB, plus any offset required by firmware. The firmware offset is encoded in the "dma-ranges" property. On machines with 30GB or more of memory, we are unable to place the fixed mapping above the normal IOMMU window as we would run out of address space. Instead we move the normal IOMMU window to coincide with the hash page table, this region does not need to be part of the fixed mapping as no device should ever be DMA'ing to it. We then setup the fixed mapping from 0 to 32GB. Signed-off-by: NMichael Ellerman <michael@ellerman.id.au> Acked-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NPaul Mackerras <paulus@samba.org>

Add support to cell_iommu_setup_page_tables() for handling two windows, the dynamic window and the fixed window. A fixed window size of 0 indicates that there is no fixed window at all. Currently there are no callers who pass a non-zero fixed window, but the upcoming fixed IOMMU mapping patch will change that.

In order to support the fixed IOMMU mapping (in a subsequent patch), we need the hash table to be inside the IOMMUs DMA window. This is usually 2G, but let's make sure the hash table is under 1G as that will satisfy the IOMMU requirements and also means the hash table will be on node 0.

Tony says: | The CONFIG_SMP=n path in ia64 makes quite radical changes ... rather | than putting all the per-cpu stuff into the top 64K of address space | and providing a per-cpu TLB mapping for that range to a different | physical address ... it just makes all the per-cpu stuff link as ordinary | variables in .data. the new generic percpu code got confused about this as PER_CPU_ATTRIBUTES was defined even on UP, so it picked up that small memory model - which was not possible to get linked. The right fix is to only define that on SMP. This resolved the build failures in my cross-compiling environment. also link these variables into the .percpu section even on UP - some assembly code has offset dependencies.

read_rom() obtained a fresh new fw_device.generation for each read transaction. Hence it was able to continue reading in the middle of the ROM even if a bus reset happened. However the device may have modified the ROM during the reset. We would end up with a corrupt fetched ROM image then. Although all of this is quite unlikely, it is not impossible. Therefore we now restart reading the ROM if the bus generation changed. Note, the memory barrier in read_rom() is still necessary according to tests by Jarod Wilson, despite of the ->generation access being moved up in the call chain.
