* backlight: lp855x: move backlight mode platform dataKim, Milo2013-04-301-6/+15
| | | | | | | | | | | | | | | | | | The brightness of LP855x devices is controlled by I2C register or PWM input . This mode was selected through the platform data, but it can be chosen by the driver internally without platform data configuration. How to decide the control mode: If the PWM period has specific value, the mode is PWM input. On the other hand, the mode is register-based. This mode selection is done on the _probe(). Move 'mode' from a header file to the driver private data structure, 'lp855 x'. And correlated code was replaced.

* drivers/video/backlight/platform_lcd.c: introduce probe callbackAndrew Bresticker2013-04-301-0/+6
| | | | | | | | | | | | | | | | Platform LCD devices may need to do some device-specific initialization before they can be used (regulator or GPIO setup, for example), but currently the driver does not support any way of doing this. This patch adds a probe() callback to plat_lcd_data which platform LCD devices can set to indicate that device-specific initialization is needed.

* misc: generic on-chip SRAM allocation driverPhilipp Zabel2013-04-303-0/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver requests and remaps a memory region as configured in the device tree. It serves memory from this region via the genalloc API. It optionally enables the SRAM clock. Other drivers can retrieve the genalloc pool from a phandle pointing to this drivers' device node in the device tree. The allocation granularity is hard-coded to 32 bytes for now, to make the SRAM driver useful for the 6502 remoteproc driver. There is overhead for bigger SRAMs, where only a much coarser allocation granularity is needed: At 32 bytes minimum allocation size, a 256 KiB SRAM needs a 1 KiB bitmap to track allocations.

In my system, node numbers of cpu#30-44 and 75-89 were changed from 2 to 0 as follows: $ numactl --hardware available: 2 nodes (0-1) node 0 cpus: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 node 0 size: 32394 MB node 0 free: 27898 MB node 1 cpus: 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 node 1 size: 32768 MB node 1 free: 30335 MB If we hot add memory to memoryless node and offine/online all CPUs on the node, node numbers of these CPUs are changed to correct node numbers by srat_detect_node() because the node become online. In this case, node numbers of cpu#30-44 and 75-89 were changed from 0 to 2 in my system as follows: $ numactl --hardware available: 3 nodes (0-2) node 0 cpus: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 node 0 size: 32394 MB node 0 free: 27218 MB node 1 cpus: 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 node 1 size: 32768 MB node 1 free: 30014 MB node 2 cpus: 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 node 2 size: 16384 MB node 2 free: 16384 MB But "cpu to node" and "node to cpu" links were not changed as follows: $ ls /sys/devices/system/cpu/cpu30/|grep node node0 $ ls /sys/devices/system/node/node0/|grep cpu30 cpu30 "numactl --hardware" shows that cpu30 belongs to node 2. But sysfs links does not change. This patch changes "cpu to node" and "node to cpu" links when node number changed by onlining CPU.

* firmware, memmap: fix firmware_map_entry leakYasuaki Ishimatsu2013-04-301-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When hot removing memory, a firmware_map_entry which has memory range of the memory is released by release_firmware_map_entry(). If the entry is allocated by bootmem, release_firmware_map_entry() adds the entry to map_entires_bootmem list when firmware_map_find_entry() finds the entry from map_entries list. But firmware_map_find_entry never find the entry sicne map_entires list does not have the entry. So the entry just leaks. Here are steps of leaking firmware_map_entry: firmware_map_remove() -> firmware_map_find_entry() Find released entry from map_entries list -> firmware_map_remove_entry() Delete the entry from map_entries list -> remove_sysfs_fw_map_entry() ... -> release_firmware_map_entry() -> firmware_map_find_entry() Find the entry from map_entries list but the entry has been deleted from map_entries list. So the entry is not added to map_entries_bootmem. Thus the entry leaks release_firmware_map_entry() should not call firmware_map_find_entry() since releaed entry has been deleted from map_entries list. So the patch delete firmware_map_find_entry() from releae_firmware_map_entry() Signed-off-by: Yasuaki Ishimatsu <isimatu.yasuaki@jp.fujitsu.com> Reviewed-by: Wanpeng Li <liwanp@linux.vnet.ibm.com> Reviewed-by: Tang Chen <tangchen@cn.fujitsu.com> Acked-by: Toshi Kani <toshi.kani@hp.com> Cc: Wen Congyang <wency@cn.fujitsu.com> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* mm, hotplug: avoid compiling memory hotremove functions when disabledDavid Rientjes2013-04-301-21/+23
| | | | | | | | | | | | | | | | | | | | | | | | | __remove_pages() is only necessary for CONFIG_MEMORY_HOTREMOVE. PowerPC pseries will return -EOPNOTSUPP if unsupported. Adding an #ifdef causes several other functions it depends on to also become unnecessary, which saves in .text when disabled (it's disabled in most defconfigs besides powerpc, including x86). remove_memory_block() becomes static since it is not referenced outside of drivers/base/memory.c. Build tested on x86 and powerpc with CONFIG_MEMORY_HOTREMOVE both enabled and disabled.
