2014-08-26arch/mips/net/bpf_jit.c: fix failure checkAndrey Utkin
static int pkt_type_offset(void) returned -1 in case of failure, and actual (positive) offset value in case of success. In the only instance of its usage, the result was saved to local "unsigned int off" variable, which is used in a lot of places in the same (large) function, so changing its type could cause many warnings. So new signed int variable was added.

2014-08-26MIPS: OCTEON: make get_system_type() thread-safeAaro Koskinen
get_system_type() is not thread-safe on OCTEON. It uses static data, also more dangerous issue is that it's calling cvmx_fuse_read_byte() every time without any synchronization. Currently it's possible to get processes stuck looping forever in kernel simply by launching multiple readers of /proc/cpuinfo: (while true; do cat /proc/cpuinfo > /dev/null; done) & (while true; do cat /proc/cpuinfo > /dev/null; done) & ...

Rename 'eva_entry' to 'platform_eva_init' as required by the new 'eva_init' macro in the eva.h header. Since this macro is now used in a platform dependent way, it must not depend on its caller so move the t1 register initialization inside this macro. Also set the .reorder assembler option in case the caller may have previously set .noreorder. This may allow a few assembler optimizations. Finally include missing headers and document the register usage for this macro.

Generic code may need to perform certain operations when EVA is enabled, for example, configure the segmentation registers during boot. In order to avoid using more CONFIG_EVA ifdefs in the arch code, such functions will be added in this header instead. Initially this header contains a macro which will be used by generic code later on during VPEs configuration on secondary cores. All it does is to call the platform specific EVA init code in case EVA is enabled.

2014-08-26MIPS: scall64-o32: Fix indirect syscall detectionMarkos Chandras
Commit 4c21b8fd8f14 (MIPS: seccomp: Handle indirect system calls (o32)) added indirect syscall detection for O32 processes running on MIPS64 but it did not work as expected. The reason is the the scall64-o32 implementation differs compared to scall32-o32. In the former, the v0 (syscall number) register contains the absolute syscall number (4000 + X) whereas in the latter it contains the relative syscall number (X). Fix the code to avoid doing an extra addition, and load the v0 register directly to the first argument for syscall_trace_enter. Moreover, set the .reorder assembler option in order to have better control on this part of the assembly code.

2014-08-26MIPS: Remove race window in page fault handlingLars Persson
Multicore MIPSes without I/D hardware coherency suffered from a race condition in the page fault handler. The page table entry was published before any pending lazy D-cache flush was committed, hence it allowed execution of stale page cache data by other VPEs in the system. To make the cache handling safe we need to perform flushing already in the set_pte_at function. MIPSes without coherent I-caches can get a small increase in flushes due to the unavailability of the execute flag in set_pte_at.

2014-08-26MIPS: Malta: Improve system memory detection for '{e, }memsize' >= 2GMarkos Chandras
Using kstrtol to parse the "{e,}memsize" variables was wrong because this parses signed long numbers. In case of '{e,}memsize' >= 2G, the top bit is set, resulting to -ERANGE errors and possibly random system memory boundaries. We fix this by replacing "kstrtol" with "kstrtoul". We also improve the code to check the kstrtoul return value and print a warning if an error was returned.

2014-08-16ideapad-laptop: Constify DMI table and other r/o variablesMathias Krause
Constify the rfkill_blacklist[] DMI table, the ideapad_rfk_data[] table and the ideapad_attribute_group attribute group. There's no need to have them writeable during runtime.

2014-08-16asus-nb-wmi.c: Rename x401u quirk to wapf4Hans de Goede
The actual x401u does not use the so named x401u quirk but the x55u quirk. All that the x401u quirk does it setting wapf to 4, so rename it to wapf4 to stop the confusion. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
2014-08-16compal-laptop: correct invalid hwmon nameRoald Frederickx
Change the name of the hwmon interface from "compal-laptop" to "compal". A dash is an invalid character for a hwmon name and caused the call to hwmon_device_register_with_groups() to fail.

2014-08-16toshiba_acpi: Add Qosmio X75-A to the alt keymap dmi listAzael Avalos
The Toshiba Qosmio X75-A series models also come with the new keymap layout. This patch adds this model to the alt_keymap_dmi list, along with an extra key found on these models. Signed-off-by: Azael Avalos <coproscefalo@gmail.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
2014-08-16toshiba_acpi: Add extra check to backlight codeAzael Avalos
Some Toshiba models (most notably Qosmios) come with an incomplete backlight method where the AML code doesn't check for write or read commands and always returns HCI_SUCCESS and the actual brightness (and in some cases the max brightness), thus allowing the backlight interface to be registered without write support. This patch changes the set_lcd_brightness function, checking the returned values for values greater than zero to avoid registering a broken backlight interface.

2014-08-16thinkpad_acpi: Mark volume_alsa_control_{vol,mute} as __initdataMathias Krause
Mark volume_alsa_control_vol and volume_alsa_control_mute as __initdata, as snd_ctl_new1() will copy the relevant parts, so there is no need to keep the master copies around after initialization.

2014-08-16fujitsu-laptop: Mark fujitsu_dmi_table[] DMI table as __initconstMathias Krause
The DMI table is only ever used during initialization. Mark it as __initconst so its memory can be released afterwards -- roughly 1.5 kB. In turn, the callback functions can be marked with __init, too.
