* m68k: Use conventional function parameters for do_sigreturnGreg Ungerer2016-02-292-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create conventional stack parameters for the calls to do_sigreturn and do_rt_sigreturn. The current C code for do_sigreturn and do_rt_sigreturn dig into the stack to create local pointers to the saved switch stack and the pt_regs structs. The motivation for this change is a problem with non-MMU targets that have broken signal return paths on newer versions of gcc. It appears as though gcc has determined that the pointers into the saved stack structs, and the saved structs themselves, are function parameters and updates to them will be lost on function return, so they are optimized away. This results in large parts of restore_sigcontext() and mangle_kernel_stack() functions being removed. Of course this results in non-functional code causing kernel oops. This problem has been observed with gcc version 5.2 and 5.3, and probably exists in earlier versions as well. Using conventional stack parameter pointers passed to these functions has the advantage of the code here not needing to know the exact details of how the underlying entry handler layed these structs out on the stack. So the rather ugly pointer setup casting and arg referencing can be removed. The resulting code after this change is a few bytes larger (due to the overhead of creating the stack args and their tear down). Not being hot paths I don't think this is too much of a problem here. An alternative solution is to put a barrier() in the do_sigreturn() code, but this doesn't feel quite as clean as this solution. This change has been compile tested on all defconfigs, and run tested on Atari (through aranym), ColdFire with MMU (M5407EVB) and ColdFire with no-MMU (QEMU and M5208EVB).

As all the device drivers are missing this is still of limited use. - Some Loongson3 cleanups. - The unavoidable whitespace polishing. - Reduce clock skew when synchronizing the CPU cycle counters on CPU startup. - Add MIPS R6 fixes. - Lots of cleanups across arch/mips as fallout from KVM. - Lots of minor fixes and changes for IEEE 754-2008 support to the FPU emulator / fp-assist software. - Minor Ralink, BCM47xx and bcm963xx platform support improvments. - Support SMP on BCM63168" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (84 commits) MIPS: zboot: Add support for serial debug using the PROM MIPS: zboot: Avoid useless rebuilds MIPS: BMIPS: Enable ARCH_WANT_OPTIONAL_GPIOLIB MIPS: bcm63xx: nvram: Remove unused bcm63xx_nvram_get_psi_size() function MIPS: bcm963xx: Update bcm_tag field image_sequence MIPS: bcm963xx: Move extended flash address to bcm_tag header file MIPS: bcm963xx: Move Broadcom BCM963xx image tag data structure MIPS: bcm63xx: nvram: Use nvram structure definition from header file MIPS: bcm963xx: Add Broadcom BCM963xx board nvram data structure MAINTAINERS: Add KVM for MIPS entry MIPS: KVM: Add missing newline to kvm_err() MIPS: Move KVM specific opcodes into asm/inst.h MIPS: KVM: Use cacheops.h definitions MIPS: Break down cacheops.h definitions MIPS: Use EXCCODE_ constants with set_except_vector() MIPS: Update trap codes MIPS: Move Cause.ExcCode trap codes to mipsregs.h MIPS: KVM: Make kvm_mips_{init,exit}() static MIPS: KVM: Refactor added offsetof()s MIPS: KVM: Convert EXPORT_SYMBOL to _GPL ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel currently assumes that a core will start up in legacy mode using the exception base provided through the CM GCR registers.

| * | MIPS: Add support for PIC32MZDA platformJoshua Henderson2016-01-2422-0/+1476
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the Microchip PIC32 MIPS microcontroller with the specific variant PIC32MZDA. PIC32MZDA is based on the MIPS m14KEc core and boots using device tree. This includes an early pin setup and early clock setup needed prior to device tree being initialized. In additon, an interface is provided to synchronize access to registers shared across several peripherals.

It handles all internal and external interrupts. This controller exists outside of the CPU core and is the arbitrator of all interrupts (including interrupts from the CPU itself) before they are presented to the CPU. The following features are supported: - DT properties for EVIC and for devices/peripherals that use interrupt lines - Persistent and non-persistent interrupt handling - irqdomain and generic chip support - Configuration of external interrupt edge polarity Signed-off-by: Cristian Birsan <[email protected]> Signed-off-by: Joshua Henderson <[email protected]> Acked-by: Thomas Gleixner <[email protected]> Cc: Jason Cooper <[email protected]> Cc: Marc Zyngier <[email protected]> Cc: [email protected] Cc: [email protected] Patchwork: https://patchwork.linux-mips.org/patch/12092/ Signed-off-by: Ralf Baechle <[email protected]>

This is 0x0c00 and represents the microMIPS `MOVE16 $0, $0' operation, whereas MIPS16 NOP is encoded as 0x6500, representing `MOVE $0, $16'. Also fix a typo in `mm_fp0_format' description.
