If dell_new_hk_type is true, dell_legacy_wmi_keymap will point to a memory allocated in setup_new_hk_map(). In this case, the memory is not freed in current implementation. This patch fixes the leak by kfree(dell_wmi_keymap) if dell_new_hk_type is true. Signed-off-by: NAxel Lin <axel.lin@gmail.com> Signed-off-by: NMatthew Garrett <mjg@redhat.com>

When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER, the caller must kfree the returned buffer if AE_OK is returned. The callers of wmi_get_event_data() pass ACPI_ALLOCATE_BUFFER, and thus must check its return value before accessing or kfree() on the buffer. This patch adds return value checking for wmi_get_event_data() and adds a missing kfree(obj) in the end of wmi_notify_debug Signed-off-by: NAxel Lin <axel.lin@gmail.com> Acked-by: NThomas Renninger <trenn@suse.de> Signed-off-by: NMatthew Garrett <mjg@redhat.com>

Stanse found that there are two NULL checks missing in ips_monitor. So check their value too and bail out appropriately if the allocation failed. While at it, add one more kfree to the fail path. It is not necessary now, but may be needed in the future when a new allocation is added. And for completeness. Also remove unneeded initialization of the variables. They are all set right after their declaration. Signed-off-by: NJiri Slaby <jslaby@suse.cz> Signed-off-by: NMatthew Garrett <mjg@redhat.com> Acked-by: NJesse Barnes <jbarnes@virtuousgeek.org>

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: NJesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: NMatthew Garrett <mjg@redhat.com>

Randy Dunlap has reported that building classmate-laptop fails when CONFIG_RFKILL=m and CONFIG_ACPI_CMPC=y. He suggested depending on RFKILL, but, then, it will not be possible to select classmate-laptop when RFKILL is off. There's no known problem with building and using classmate-laptop with RFKILL off.

- 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: NThomas Renninger <trenn@suse.de> Signed-off-by: NMatthew Garrett <mjg@redhat.com> CC: linux-acpi@vger.kernel.org CC: platform-driver-x86@vger.kernel.org

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.

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 62eede62 "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.
