2011-07-13xfs: reshuffle dir2 headersChristoph Hellwig
Replace the current mess of dir2 headers with just three that have a clear purpose: - xfs_dir2_format.h for all format definitions, including the inline helpers to access our variable size structures - xfs_dir2_priv.h for all prototypes that are internal to the dir2 code and not needed by anything outside of the directory code. For this purpose xfs_da_btree.c, and phase6.c in xfs_repair are considered part of the directory code. - xfs_dir2.h for the public interface to the directory code In addition to the reshuffle I have also update the comments to not only match the new file structure, but also to describe the directory format better.

2011-07-13xfs: start periodic workers laterChristoph Hellwig
Start the periodic sync workers only after we have finished xfs_mountfs and thus fully set up the filesystem structures. Without this we can call into xfs_qm_sync before the quotainfo strucute is set up if the mount takes unusually long, and probably hit other incomplete states as well. Also clean up the xfs_fs_fill_super error path by using consistent label names, and removing an impossible to reach case.

2011-07-13slip: remove dead code within the slip initializationMatvejchikov Ilya
This following code contains a dead "if (dev).." block: ... for (i = 0; i < slip_maxdev; i++) { dev = slip_devs[i]; if (dev == NULL) break; } /* Sorry, too many, all slots in use */ if (i >= slip_maxdev) return NULL; if (dev) { sl = netdev_priv(dev); if (test_bit(SLF_INUSE, &sl->flags)) { unregister_netdevice(dev); dev = NULL; slip_devs[i] = NULL; } } ... The reason is that the code starting with "if (dev).." is never called as when we found an empty slot (dev == NULL) we break the loop and "if (dev).." not works eiter the loop ends and we get out with "i >= slip_maxdev".

2011-07-12x86, numa: Implement pfn -> nid mapping granularity checkTejun Heo
SPARSEMEM w/o VMEMMAP and DISCONTIGMEM, both used only on 32bit, use sections array to map pfn to nid which is limited in granularity. If NUMA nodes are laid out such that the mapping cannot be accurate, boot will fail triggering BUG_ON() in mminit_verify_page_links(). On 32bit, it's 512MiB w/ PAE and SPARSEMEM. This seems to have been granular enough until commit 2706a0bf7b (x86, NUMA: Enable CONFIG_AMD_NUMA on 32bit too). Apparently, there is a machine which aligns NUMA nodes to 128MiB and has only AMD NUMA but not SRAT. This led to the following BUG_ON(). On node 0 totalpages: 2096615 DMA zone: 32 pages used for memmap DMA zone: 0 pages reserved DMA zone: 3927 pages, LIFO batch:0 Normal zone: 1740 pages used for memmap Normal zone: 220978 pages, LIFO batch:31 HighMem zone: 16405 pages used for memmap HighMem zone: 1853533 pages, LIFO batch:31 BUG: Int 6: CR2 (null) EDI (null) ESI 00000002 EBP 00000002 ESP c1543ecc EBX f2400000 EDX 00000006 ECX (null) EAX 00000001 err (null) EIP c16209aa CS 00000060 flg 00010002 Stack: f2400000 00220000 f7200800 c1620613 00220000 01000000 04400000 00238000 (null) f7200000 00000002 f7200b58 f7200800 c1620929 000375fe (null) f7200b80 c16395f0 00200a02 f7200a80 (null) 000375fe 00000002 (null) Pid: 0, comm: swapper Not tainted 2.6.39-rc5-00181-g2706a0b #17 Call Trace: [<c136b1e5>] ? early_fault+0x2e/0x2e [<c16209aa>] ? mminit_verify_page_links+0x12/0x42 [<c1620613>] ? memmap_init_zone+0xaf/0x10c [<c1620929>] ? free_area_init_node+0x2b9/0x2e3 [<c1607e99>] ? free_area_init_nodes+0x3f2/0x451 [<c1601d80>] ? paging_init+0x112/0x118 [<c15f578d>] ? setup_arch+0x791/0x82f [<c15f43d9>] ? start_kernel+0x6a/0x257 This patch implements node_map_pfn_alignment() which determines maximum internode alignment and update numa_register_memblks() to reject NUMA configuration if alignment exceeds the pfn -> nid mapping granularity of the memory model as determined by PAGES_PER_SECTION.

2011-07-12x86, mm: s/PAGES_PER_ELEMENT/PAGES_PER_SECTION/Tejun Heo
DISCONTIGMEM on x86-32 implements pfn -> nid mapping similarly to SPARSEMEM; however, it calls each mapping unit ELEMENT instead of SECTION. This patch renames it to SECTION so that PAGES_PER_SECTION is valid for both DISCONTIGMEM and SPARSEMEM. This will be used by the next patch to implement mapping granularity check.

Remove barriers.h from Tegra, and don't select ARCH_HAS_BARRIERS. Signed-off-by: Colin Cross <ccross@android.com> Acked-by: Olof Johansson <olof@lixom.net>
2011-07-12ARM: Tegra: Seaboard: Re-order sdhci device registrationStephen Warren
Ensure the built-in eMMC is always named mmcblk0. This is important because: * U-Boot statically assigns MMC device IDs based on controller ID. * U-Boot assumes that kernel MMC device ID numbering matches U-Boot numbering. * U-Boot provides a kernel cmdline option e.g. root=/dev/mmcblk0p3 based on that numbering. * The kernel dynamically assigns MMC device IDs based on enumeration order of the memory behind the host controller, rather than statically based on host controller ID like U-Boot. * By registering the SDHCI controller for the built-in eMMC first, the enumeration of the built-in eMMC is performed first, and hence eMMC gets assigned ID 0 just like U-Boot. If the SD slot is filled, it then gets assigned ID 1 just like U-Boot. * If the MMC IDs mismatch, and the system boots from SD card not eMMC, the kernel will access the eMMC instead of SD card when attempting to mount /dev/mmcblk1p3 as the root fs. If eMMC is not partitioned/formatted, the kernel will panic since the root fs can't be mounted. If eMMC is partitioned and formatted, the kernel will mount an unexpected filesystem as the root fs. This change relies on the SDHCI driver performing initial card detection synchronously during device registration. This is currently the case.

2011-07-12x86, ioapic: Print IRTE when IR is enabledNaga Chumbalkar
When "apic=debug" is used as a boot parameter, Linux prints the IOAPIC routing entries in "dmesg". Below is output from IOAPIC whose apic_id is 8: # dmesg | grep "routing entry" IOAPIC[8]: Set routing entry (8-1 -> 0x31 -> IRQ 1 Mode:0 Active:0 Dest:0) IOAPIC[8]: Set routing entry (8-2 -> 0x30 -> IRQ 0 Mode:0 Active:0 Dest:0) IOAPIC[8]: Set routing entry (8-3 -> 0x33 -> IRQ 3 Mode:0 Active:0 Dest:0) ... Similarly, when IR (interrupt remapping) is enabled, and the IRTE (interrupt remapping table entry) is set up we should display it. After the fix: # dmesg | grep IRTE IOAPIC[8]: Set IRTE entry (P:1 FPD:0 Dst_Mode:0 Redir_hint:1 Trig_Mode:0 Dlvry_Mode:0 Avail:0 Vector:31 Dest:00000000 SID:00F1 SQ:0 SVT:1) IOAPIC[8]: Set IRTE entry (P:1 FPD:0 Dst_Mode:0 Redir_hint:1 Trig_Mode:0 Dlvry_Mode:0 Avail:0 Vector:30 Dest:00000000 SID:00F1 SQ:0 SVT:1) IOAPIC[8]: Set IRTE entry (P:1 FPD:0 Dst_Mode:0 Redir_hint:1 Trig_Mode:0 Dlvry_Mode:0 Avail:0 Vector:33 Dest:00000000 SID:00F1 SQ:0 SVT:1) ...

2011-07-12dlm: improve rsb searchesDavid Teigland
By pre-allocating rsb structs before searching the hash table, they can be inserted immediately. This avoids always having to repeat the search when adding the struct to hash list. This also adds space to the rsb struct for a max resource name, so an rsb allocation can be used by any request. The constant size also allows us to finally use a slab for the rsb structs.

2011-07-12OMAP: PM: disable idle on suspend for GPIO and UARTKevin Hilman
Until these drivers are runtime PM converted, their device power states are managed by calling custom driver hooks late in the idle/suspend path. Therefore, do not let the suspend/resume core code automatically idle these devices since they will be managed manually by the OMAP PM core very late in the idle/suspend path.
