2008-04-27KVM: align valid EFER bits with the features of the host systemJoerg Roedel
This patch aligns the bits the guest can set in the EFER register with the features in the host processor. Currently it lets EFER.NX disabled if the processor does not support it and enables EFER.LME and EFER.LMA only for KVM on 64 bit hosts.

2008-04-27KVM: MMU: Decouple mmio from shadow page tablesAvi Kivity
Currently an mmio guest pte is encoded in the shadow pagetable as a not-present trapping pte, with the SHADOW_IO_MARK bit set. However nothing is ever done with this information, so maintaining it is a useless complication. This patch moves the check for mmio to before shadow ptes are instantiated, so the shadow code is never invoked for ptes that reference mmio. The code is simpler, and with future work, can be made to handle mmio concurrently. Signed-off-by: Avi Kivity <avi@qumranet.com>

2008-04-27KVM: x86 emulator: add support for group decodingAvi Kivity
Certain x86 instructions use bits 3:5 of the byte following the opcode as an opcode extension, with the decode sometimes depending on bits 6:7 as well. Add support for this in the main decoding table rather than an ad-hock adaptation per opcode. Signed-off-by: Avi Kivity <avi@qumranet.com>

2008-04-27KVM: MMU: Update shadow ptes on partial guest pte writesDong, Eddie
A guest partial guest pte write will leave shadow_trap_nonpresent_pte in spte, which generates a vmexit at the next guest access through that pte. This patch improves this by reading the full guest pte in advance and thus being able to update the spte and eliminate the vmexit. This helps pae guests which use two 32-bit writes to set a single 64-bit pte.

2008-04-26x86_64: fix setup_node_bootmem to support big mem excluding with memmapYinghai Lu
typical case: four sockets system, every node has 4g ram, and we are using: memmap=10g$4g to mask out memory on node1 and node2 when numa is enabled, early_node_mem is used to get node_data and node_bootmap. if it can not get memory from the same node with find_e820_area(), it will use alloc_bootmem to get buff from previous nodes. so check it and print out some info about it. need to move early_res_to_bootmem into every setup_node_bootmem. and it takes range that node has. otherwise alloc_bootmem could return addr that reserved early. depends on "mm: make reserve_bootmem can crossed the nodes".

2008-04-26x86_64: make reserve_bootmem_generic() use new reserve_bootmem()Yinghai Lu
"mm: make reserve_bootmem can crossed the nodes" provides new reserve_bootmem(), let reserve_bootmem_generic() use that. reserve_bootmem_generic() is used to reserve initramdisk, so this way we can make sure even when bootloader or kexec load ranges cross the node memory boundaries, reserve_bootmem still works.

2008-04-26mm: allow reserve_bootmem() cross nodesYinghai Lu
split reserve_bootmem_core() into two functions, one which checks conflicts, and one which sets the bits. and make reserve_bootmem to loop bdata_list to cross the nodes. user could be crashkernel and ramdisk..., in case the range provided by those externalities crosses the nodes.

2008-04-26mm: offset align in alloc_bootmem()Yinghai Lu
need offset alignment when node_boot_start's alignment is less than the alignment required. use local node_boot_start to match alignment - so don't add extra operation in search loop. Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26mm: fix alloc_bootmem_core to use fast searching for all nodesYinghai Lu
Make the nodes other than node 0 use bdata->last_success for fast search too. We need to use __alloc_bootmem_core() for vmemmap allocation for other nodes when numa and sparsemem/vmemmap are enabled. Also, make fail_block path increase i with incr only after ALIGN to avoid extra increase when size is larger than align.

2008-04-26mm: make mem_map allocation continuousYinghai Lu
vmemmap allocation currently has this layout: [ffffe20000000000-ffffe200001fffff] PMD ->ffff810001400000 on node 0 [ffffe20000200000-ffffe200003fffff] PMD ->ffff810001800000 on node 0 [ffffe20000400000-ffffe200005fffff] PMD ->ffff810001c00000 on node 0 [ffffe20000600000-ffffe200007fffff] PMD ->ffff810002000000 on node 0 [ffffe20000800000-ffffe200009fffff] PMD ->ffff810002400000 on node 0 ... note that there is a 2M hole between them - not optimal. the root cause is that usemap (24 bytes) will be allocated after every 2M mem_map, and it will push next vmemmap (2M) to the next (2M) alignment. solution: try to allocate the mem_map continously. after the patch, we get: [ffffe20000000000-ffffe200001fffff] PMD ->ffff810001400000 on node 0 [ffffe20000200000-ffffe200003fffff] PMD ->ffff810001600000 on node 0 [ffffe20000400000-ffffe200005fffff] PMD ->ffff810001800000 on node 0 [ffffe20000600000-ffffe200007fffff] PMD ->ffff810001a00000 on node 0 [ffffe20000800000-ffffe200009fffff] PMD ->ffff810001c00000 on node 0 ... which is the ideal layout. and usemap will share a page because of they are allocated continuously too: sparse_early_usemap_alloc: usemap = ffff810024e00000 size = 24 sparse_early_usemap_alloc: usemap = ffff810024e00080 size = 24 sparse_early_usemap_alloc: usemap = ffff810024e00100 size = 24 sparse_early_usemap_alloc: usemap = ffff810024e00180 size = 24 ... so we make the bootmem allocation more compact and use less memory for usemap => mission accomplished ;-) Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-26alim15x3: skip DMA initialization completely on revs < 0x20Bartlomiej Zolnierkiewicz
Skip DMA initialization completely on revs < 0x20 by setting IDE_HFLAG_NO_DMA host flag and resetting DMA host masks in alim15x3_init_one() (currently ide_hwif_setup_dma() will try to obtain DMA base and setup PCI bus-mastering but init_dma_ali15x3() will fail).

2008-04-26pdc202xx_old: remove init_dma_pdc202xx()Bartlomiej Zolnierkiewicz
Do PDC202xx specific DMA initialization in init_chipset_pdc202xx() and remove no longer needed init_dma_pdc202xx(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-26ide: don't display "BIOS" settings in ide_setup_dma()Bartlomiej Zolnierkiewicz
Nowadays BIOS info is not very useful and only confuses users since: - IDE always tries to use DMA - BIOS info may not be accurate with modular IDE/libata Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-26ide: remove ->cds field from ide_hwif_t (take 2)Bartlomiej Zolnierkiewicz
* Use hwif->name instead of cds->name in ide_allocate_dma_engine(). * Use pci_name(dev) instead of cds->name in init_dma_pdc202xx(). * Remove no longer needed ->cds field from ide_hwif_t. v2: * scc_pata.c also needs to be updated now (noticed by Stephen Rothwell). There should be no functional changes caused by this patch.

2008-04-26ide: remove ide_dma_iobase()Bartlomiej Zolnierkiewicz
* ide_mapped_mmio_dma() and ide_iomio_dma() are called only by ide_dma_iobase() so inline them there. * ide_dma_iobase() is called only by ide_setup_dma() so inline it there. * Setup hwif->extra_base also if hwif->mmio flag is set.

2008-04-26ide: remove ->extra field from struct ide_port_infoBartlomiej Zolnierkiewicz
Always setup hwif->extra_base in ide_iomio_dma() and remove no longer needed ->extra field from struct ide_port_info. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
