| * | MIPS: pm-cps: Use MIPS standard completion barrierMatt Redfearn2016-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SYNC type 0 is defined in the MIPS architecture as a completion barrier where all loads/stores in the pipeline before the sync instruction must complete before any loads/stores subsequent to the sync instruction. In places where we require loads / stores be globally completed, use the standard completion sync stype.

| * | MIPS: pm-cps: Use MIPS standard lightweight ordering barrierMatt Redfearn2016-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since R2 of the MIPS architecture, SYNC(0x10) has been an optional but architecturally defined ordering barrier. If a CPU does not implement it, the arch specifies that it must fall back to SYNC(0). In places where we require that the instruction stream not be reordered, but do not require that loads / stores are gloablly completed, use the defined standard sync stype.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the definitions of sync stype 0 (global completion barrier) and sync stype 0x10 (local ordering barrier) to barrier.h for use with the sync instruction. These types are defined by the MIPS Instruction Set since R2 of the architecture and are documented in document MD00087 table 6.5.

| * | MIPS: pm-cps: Change FSB workaround to CPU blacklistMatt Redfearn2016-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The check for whether a CPU required the FSB flush workaround previously required every CPU not requiring it to be whitelisted. That approach does not scale well as new CPUs are introduced so change the default from a WARN and returning an error to just returning 0. Any CPUs requiring the workaround can then be added to the blacklist.

| * | MIPS: CPC: Avoid lock when MIPS CM >= 3 is presentMatt Redfearn2016-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MIPS CM version 3 removed the CPC_CL_OTHER register and instead the CM_CL_OTHER register is used to redirect the CPC_OTHER region. As such, we should not write the unimplmented register and can avoid the spinlock as well. These lock functions should aleady be called within the context of a mips_cm_{lock,unlock}_other pair ensuring the correct CPC_OTHER region will be accessed.

| * | MIPS: Don't specify STACKPROTECTOR in defconfigsPaul Gortmaker2016-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only one defconfig has a STACKPROTECTOR value. And it asks for the strong variant, which isn't supported by older toolchains. Due to the nature of MIPS having more platform specific code than say x86, the allyesconfig and allmodconfig aren't as effective for build coverage. So, in addition, I like to use a trivial script to walk all the defconfigs and build each one. However I will get false positives on unsupported stackprotector values with an older toolchain like gcc-4.6.3. As in this instance I am just using the compiler as a glorified syntax checker on a machine where I build a bunch of other arch for the same reason, there is no real motivation to get a newer toolchain for improved optimization etc. Since there is only one of them, and there is nothing about these settings that are board/platform specific, I propose we just eliminate the existing instance and take the default.

* | | mips/panic: replace smp_send_stop() with kdump friendly version in panic pathHidehiro Kawai2016-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Daniel Walker reported problems which happens when crash_kexec_post_notifiers kernel option is enabled (https://lkml.org/lkml/2015/6/24/44). In that case, smp_send_stop() is called before entering kdump routines which assume other CPUs are still online. As the result, kdump routines fail to save other CPUs' registers. Additionally for MIPS OCTEON, it misses to stop the watchdog timer. To fix this problem, call a new kdump friendly function, crash_smp_send_stop(), instead of the smp_send_stop() when crash_kexec_post_notifiers is enabled. crash_smp_send_stop() is a weak function, and it just call smp_send_stop(). Architecture codes should override it so that kdump can work appropriately. This patch provides MIPS version.
