2013-08-29spi: nuc900: Fix mode_bits settingAxel Lin
The code in nuc900_slave_select() supports handling SPI_CS_HIGH. Thus set SPI_CS_HIGH bit in master->mode_bits to make it work. Otherwise, spi_setup() will return unsupported mode bits error message if SPI_CS_HIGH is set in the mode field of struct spi_device.

2013-08-29spi: simplify devm_request_mem_region/devm_ioremapJulia Lawall
Convert the composition of devm_request_mem_region and devm_ioremap to a single call to devm_ioremap_resource. The associated call to platform_get_resource is also simplified and moved next to the new call to devm_ioremap_resource. This was done using a combination of the semantic patches devm_ioremap_resource.cocci and devm_request_and_ioremap.cocci, found in the scripts/coccinelle/api directory. This patch also removes the label exit_busy, to use the error code returned by the failing operation, rather than always -EBUSY.

2013-08-29regmap: rbtree: Make cache_present bitmap per nodeLars-Peter Clausen
With devices which have a dense and small register map but placed at a large offset the global cache_present bitmap imposes a huge memory overhead. Making the cache_present per rbtree node avoids the issue and easily reduces the memory footprint by a factor of ten. For devices with a more sparse map or without a large base register offset the memory usage might increase slightly by a few bytes, but not significantly. E.g. for a device which has ~50 registers at offset 0x4000 the memory footprint of the register cache goes down form 2496 bytes to 175 bytes. Moving the bitmap to a per node basis means that the handling of the bitmap is now cache implementation specific and can no longer be managed by the core. The regcache_sync_block() function is extended by a additional parameter so that the cache implementation can tell the core which registers in the block are set and which are not. The parameter is optional and if NULL the core assumes that all registers are set. The rbtree cache also needs to implement its own drop callback instead of relying on the core to handle this.

2013-08-29regmap: rbtree: Reduce number of nodes, take 2Lars-Peter Clausen
Support for reducing the number of nodes and memory consumption of the rbtree cache by allowing for small unused holes in the node's register cache block was initially added in commit 0c7ed856 ("regmap: Cut down on the average # of nodes in the rbtree cache"). But the commit had problems and so its effect was reverted again in commit 4e67fb5 ("regmap: rbtree: Fix overlapping rbnodes."). This patch brings the feature back of reducing the average number of nodes, which will speedup node look-up, while at the same time also reducing the memory usage of the rbtree cache. This patch takes a slightly different approach than the original patch though. It modifies the adjacent node look-up to not only consider nodes that are just one to the left or the right of the register but any node that falls in a certain range around the register. The range is calculated based on how much memory it would take to allocate a new node compared to how much memory it takes adding a set of unused registers to an existing node. E.g. if a node takes up 24 bytes and each register in a block uses 1 byte the range will be from the register address - 24 to the register address + 24. If we find a node that falls within this range it is cheaper or as expensive to add the register to the existing node and have a couple of unused registers in the node's cache compared to allocating a new node.

2013-08-29regmap: rbtree: Simplify adjacent node look-upLars-Peter Clausen
A register which is adjacent to a node will either be left to the first register or right to the last register. It will not be within the node's range, so there is no point in checking for each register cached by the node whether the new register is next to it. It is sufficient to check whether the register comes before the first register or after the last register of the node.

2013-08-28PCI: Support PCIe Capability Slot registers only for ports with slotsBjorn Helgaas
Previously we allowed callers to access Slot Capabilities, Status, and Control for Root Ports even if the Root Port did not implement a slot. This seems dubious because the spec only requires these registers if a slot is implemented. It's true that even Root Ports without slots must have *space* for these slot registers, because the Root Capabilities, Status, and Control registers are after the slot registers in the capability. However, for a v1 PCIe Capability, the *semantics* of the slot registers are undefined unless a slot is implemented.

2013-08-28PCI: Remove PCIe Capability version checksBjorn Helgaas
Previously we relied on the PCIe r3.0, sec 7.8, spec language that says "For Functions that do not implement the [Link, Slot, Root] registers, these spaces must be hardwired to 0b," which means that for v2 PCIe capabilities, we don't need to check the device type at all. But it's simpler if we don't need to check the capability version at all, and I think the spec is explicit enough about which registers are required for which types that we can remove the version checks.

2013-08-28drivers/base/memory.c: fix show_mem_removable() to handle missing sectionsRuss Anderson
"cat /sys/devices/system/memory/memory*/removable" crashed the system. The problem is that show_mem_removable() is passing a bad pfn to is_mem_section_removable(), which causes if (!node_online(page_to_nid(page))) to blow up. Why is it passing in a bad pfn? The reason is that show_mem_removable() will loop sections_per_block times. sections_per_block is 16, but mem->section_count is 8, indicating holes in this memory block. Checking that the memory section is present before checking to see if the memory section is removable fixes the problem. harp5-sys:~ # cat /sys/devices/system/memory/memory*/removable 0 1 1 1 1 1 1 1 1 1 1 1 1 1 BUG: unable to handle kernel paging request at ffffea00c3200000 IP: [<ffffffff81117ed1>] is_pageblock_removable_nolock+0x1/0x90 PGD 83ffd4067 PUD 37bdfce067 PMD 0 Oops: 0000 [#1] SMP Modules linked in: autofs4 binfmt_misc rdma_ucm rdma_cm iw_cm ib_addr ib_srp scsi_transport_srp scsi_tgt ib_ipoib ib_cm ib_uverbs ib_umad iw_cxgb3 cxgb3 mdio mlx4_en mlx4_ib ib_sa mlx4_core ib_mthca ib_mad ib_core fuse nls_iso8859_1 nls_cp437 vfat fat joydev loop hid_generic usbhid hid hwperf(O) numatools(O) dm_mod iTCO_wdt ipv6 iTCO_vendor_support igb i2c_i801 ioatdma i2c_algo_bit ehci_pci pcspkr lpc_ich i2c_core ehci_hcd ptp sg mfd_core dca rtc_cmos pps_core mperf button xhci_hcd sd_mod crc_t10dif usbcore usb_common scsi_dh_emc scsi_dh_hp_sw scsi_dh_alua scsi_dh_rdac scsi_dh gru(O) xvma(O) xfs crc32c libcrc32c thermal sata_nv processor piix mptsas mptscsih scsi_transport_sas mptbase megaraid_sas fan thermal_sys hwmon ext3 jbd ata_piix ahci libahci libata scsi_mod CPU: 4 PID: 5991 Comm: cat Tainted: G O 3.11.0-rc5-rja-uv+ #10 Hardware name: SGI UV2000/ROMLEY, BIOS SGI UV 2000/3000 series BIOS 01/15/2013 task: ffff88081f034580 ti: ffff880820022000 task.ti: ffff880820022000 RIP: 0010:[<ffffffff81117ed1>] [<ffffffff81117ed1>] is_pageblock_removable_nolock+0x1/0x90 RSP: 0018:ffff880820023df8 EFLAGS: 00010287 RAX: 0000000000040000 RBX: ffffea00c3200000 RCX: 0000000000000004 RDX: ffffea00c30b0000 RSI: 00000000001c0000 RDI: ffffea00c3200000 RBP: ffff880820023e38 R08: 0000000000000000 R09: 0000000000000001 R10: 0000000000000000 R11: 0000000000000001 R12: ffffea00c33c0000 R13: 0000160000000000 R14: 6db6db6db6db6db7 R15: 0000000000000001 FS: 00007ffff7fb2700(0000) GS:ffff88083fc80000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: ffffea00c3200000 CR3: 000000081b954000 CR4: 00000000000407e0 Call Trace: show_mem_removable+0x41/0x70 dev_attr_show+0x2a/0x60 sysfs_read_file+0xf7/0x1c0 vfs_read+0xc8/0x130 SyS_read+0x5d/0xa0 system_call_fastpath+0x16/0x1b Signed-off-by: Russ Anderson <rja@sgi.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: "Rafael J.

Add a new ar933x_uart_console_enabled() helper function which uses the config_enable(CONFIG_SERIAL_AR933X_CONSOLE) macro to decide if the console support is enabled or not. Remove the 'ifdef CONFIG_SERIAL_AR933X_CONSOLE' statements and use the new helper function to conditionally enable console support instead.

2013-08-28cpufreq: Fix timer/workqueue corruption due to double queueingStephen Boyd
When a CPU is hot removed we'll cancel all the delayed work items via gov_cancel_work(). Normally this will just cancels a delayed timer on each CPU that the policy is managing and the work won't run, but if the work is already running the workqueue code will wait for the work to finish before continuing to prevent the work items from re-queuing themselves like they normally do. This scheme will work most of the time, except for the case where the work function determines that it should adjust the delay for all other CPUs that the policy is managing. If this scenario occurs, the canceling CPU will cancel its own work but queue up the other CPUs works to run. For example: CPU0 CPU1 ---- ---- cpu_down() ... __cpufreq_remove_dev() cpufreq_governor_dbs() case CPUFREQ_GOV_STOP: gov_cancel_work(dbs_data, policy); cpu0 work is canceled timer is canceled cpu1 work is canceled <work runs> <waits for cpu1> od_dbs_timer() gov_queue_work(*, *, true); cpu0 work queued cpu1 work queued cpu2 work queued ... cpu1 work is canceled cpu2 work is canceled ... At the end of the GOV_STOP case cpu0 still has a work queued to run although the code is expecting all of the works to be canceled. __cpufreq_remove_dev() will then proceed to re-initialize all the other CPUs works except for the CPU that is going down. The CPUFREQ_GOV_START case in cpufreq_governor_dbs() will trample over the queued work and debugobjects will spit out a warning: WARNING: at lib/debugobjects.c:260 debug_print_object+0x94/0xbc() ODEBUG: init active (active state 0) object type: timer_list hint: delayed_work_timer_fn+0x0/0x10 Modules linked in: CPU: 0 PID: 1491 Comm: sh Tainted: G W 3.10.0 #19 [<c010c178>] (unwind_backtrace+0x0/0x11c) from [<c0109dec>] (show_stack+0x10/0x14) [<c0109dec>] (show_stack+0x10/0x14) from [<c01904cc>] (warn_slowpath_common+0x4c/0x6c) [<c01904cc>] (warn_slowpath_common+0x4c/0x6c) from [<c019056c>] (warn_slowpath_fmt+0x2c/0x3c) [<c019056c>] (warn_slowpath_fmt+0x2c/0x3c) from [<c0388a7c>] (debug_print_object+0x94/0xbc) [<c0388a7c>] (debug_print_object+0x94/0xbc) from [<c0388e34>] (__debug_object_init+0x2d0/0x340) [<c0388e34>] (__debug_object_init+0x2d0/0x340) from [<c019e3b0>] (init_timer_key+0x14/0xb0) [<c019e3b0>] (init_timer_key+0x14/0xb0) from [<c0635f78>] (cpufreq_governor_dbs+0x3e8/0x5f8) [<c0635f78>] (cpufreq_governor_dbs+0x3e8/0x5f8) from [<c06325a0>] (__cpufreq_governor+0xdc/0x1a4) [<c06325a0>] (__cpufreq_governor+0xdc/0x1a4) from [<c0633704>] (__cpufreq_remove_dev.isra.10+0x3b4/0x434) [<c0633704>] (__cpufreq_remove_dev.isra.10+0x3b4/0x434) from [<c08989f4>] (cpufreq_cpu_callback+0x60/0x80) [<c08989f4>] (cpufreq_cpu_callback+0x60/0x80) from [<c08a43c0>] (notifier_call_chain+0x38/0x68) [<c08a43c0>] (notifier_call_chain+0x38/0x68) from [<c01938e0>] (__cpu_notify+0x28/0x40) [<c01938e0>] (__cpu_notify+0x28/0x40) from [<c0892ad4>] (_cpu_down+0x7c/0x2c0) [<c0892ad4>] (_cpu_down+0x7c/0x2c0) from [<c0892d3c>] (cpu_down+0x24/0x40) [<c0892d3c>] (cpu_down+0x24/0x40) from [<c0893ea8>] (store_online+0x2c/0x74) [<c0893ea8>] (store_online+0x2c/0x74) from [<c04519d8>] (dev_attr_store+0x18/0x24) [<c04519d8>] (dev_attr_store+0x18/0x24) from [<c02a69d4>] (sysfs_write_file+0x100/0x148) [<c02a69d4>] (sysfs_write_file+0x100/0x148) from [<c0255c18>] (vfs_write+0xcc/0x174) [<c0255c18>] (vfs_write+0xcc/0x174) from [<c0255f70>] (SyS_write+0x38/0x64) [<c0255f70>] (SyS_write+0x38/0x64) from [<c0106120>] (ret_fast_syscall+0x0/0x30) Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J.

2013-08-28ACPI / EC: Add ASUSTEK L4R to quirk list in order to validate ECDTLan Tianyu
The ECDT of ASUSTEK L4R doesn't provide correct command and data I/O ports. The DSDT provides the correct information instead. For this reason, add this machine to quirk list for ECDT validation and use the EC information from the DSDT.
