2010-08-03sony-laptop: use platform_device_unregister in sony_pf_removeAxel Lin1-2/+1
platform_device_unregister calls platform_device_del and platform_device_put, thus this change is logically equivalent to original code.

2010-08-03x86 platform driver: intelligent power sharing driverJesse Barnes4-0/+1675
Intel Core i3/5 platforms with integrated graphics support both CPU and GPU turbo mode. CPU turbo mode is opportunistic: the CPU will use any available power to increase core frequencies if thermal headroom is available. The GPU side is more manual however; the graphics driver must monitor GPU power and temperature and coordinate with a core thermal driver to take advantage of available thermal and power headroom in the package. The intelligent power sharing (IPS) driver is intended to coordinate this activity by monitoring MCP (multi-chip package) temperature and power, allowing the CPU and/or GPU to increase their power consumption, and thus performance, when possible. The goal is to maximize performance within a given platform's TDP (thermal design point). Signed-off-by: Jesse Barnes <[email protected]> Signed-off-by: Matthew Garrett <[email protected]>

2010-08-03X86 platform: hp-wmi Better match the HP WMI query interfaceThomas Renninger1-30/+107
- Improve error handling, by explictly return zero for success, error otherwise - WMI query command can have arbitrary input sized params - WMI query command can have specific output sized params (0, 4, 128,..) byte I like to go on here, but this is a rather intrusive change that should be looked at first. I am sure the one or other thing can be done better or there might be typo/bug somewhere. This did not get any testing yet, only compile tested. Next steps could be: - Eventually introduce hp_wmi_perform_{read,write}_query macros - Introduce new wireless query interface (0x1B) - more Signed-off-by: Thomas Renninger <[email protected]> Signed-off-by: Matthew Garrett <[email protected]> CC: [email protected] CC: [email protected]
2010-08-03x86 platform drivers: hp-wmi fix buffer size depending on ACPI versionThomas Renninger1-7/+27
Depending on ACPI version (1.0 -> 32 bit) an integer could be 32 or 64 bit long. _WED internal concatenates two integers and the return value will be 8 byte (2* 32 bit) or 16 byte (2* 64 bit) long, depending on the ACPI version. Also the data send with the WMI event is defined to be splitted into: - Event ID -> 4 bytes - Event Data -> 4 bytes This gets messed up with new ACPI versions. But it's a HP BIOS bug that may get fixed in the future -> Support both, 16 and 8 byte _WED buffers. Also the wrong assumption that from the event data sent, only the first byte is relevant got cleaned up that it fits event_id/event_data as described above.

2010-07-30mm: fix ia64 crash when gcore reads gate areaHugh Dickins1-3/+13
Debian's ia64 autobuilders have been seeing kernel freeze or reboot when running the gdb testsuite (Debian bug 588574): dannf bisected to 2.6.32 62eede62dafb4a6633eae7ffbeb34c60dba5e7b1 "mm: ZERO_PAGE without PTE_SPECIAL"; and reproduced it with gdb's gcore on a simple target. I'd missed updating the gate_vma handling in __get_user_pages(): that happens to use vm_normal_page() (nowadays failing on the zero page), yet reported success even when it failed to get a page - boom when access_process_vm() tried to copy that to its intermediate buffer. Fix this, resisting cleanups: in particular, leave it for now reporting success when not asked to get any pages - very probably safe to change, but let's not risk it without testing exposure. Why did ia64 crash with 16kB pages, but succeed with 64kB pages? Because setup_gate() pads each 64kB of its gate area with zero pages.

2010-07-30ARM: 6279/1: highmem: fix SMP preemption bug in kmap_high_l1_viptGary King1-5/+8
smp_processor_id() must not be called from a preemptible context (this is checked by CONFIG_DEBUG_PREEMPT). kmap_high_l1_vipt() was doing so. This lead to a problem where the wrong per_cpu kmap_high_l1_vipt_depth could be incremented, causing a BUG_ON(*depth <= 0); in kunmap_high_l1_vipt(). The solution is to move the call to smp_processor_id() after the call to preempt_disable().
