Core architecture changes include: - Syscall tables & definitions for unistd.h are now generated by scripts, providing greater consistency with other architectures & making it easier to add new syscalls. - Support for building kernels with no floating point support, upon which any userland attempting to use floating point instructions will receive a SIGILL. Mostly useful to shrink the kernel & as preparation for nanoMIPS support which does not yet include FP. - MIPS SIMD Architecture (MSA) vector register context is now exposed by ptrace via a new NT_MIPS_MSA regset. - ASIDs are now stored as 64b values even for MIPS32 kernels, expanding the ASID version field sufficiently that we don't need to worry about overflow & avoiding rare issues with reused ASIDs that have been observed in the wild. - The branch delay slot "emulation" page is now mapped without write permission for the user, preventing its use as a nice location for attacks to execute malicious code from. - Support for ioremap_prot(), primarily to allow gdb or other ptrace users the ability to view their tracee's memory using the same cache coherency attribute. - Optimizations to more cpu_has_* macros, allowing more to be compile-time constant where possible. - Enable building the whole kernel with UBSAN instrumentation. - Enable building the kernel with link-time dead code & data elimination. Platform specific changes include: - The Boston board gains a workaround for DMA prefetching issues with the EG20T Platform Controller Hub that it uses. - Cleanups to Cavium Octeon code removing about 20k lines of redundant code, mostly unused or duplicate register definitions in headers. - defconfig updates for the DECstation machines, including new defconfigs for r4k & 64b machines. - Further work on Loongson 3 support. - DMA fixes for SiByte machines" * tag 'mips_4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (95 commits) MIPS: math-emu: Write-protect delay slot emulation pages MIPS: Remove struct mm_context_t fp_mode_switching field mips: generate uapi header and system call table files mips: add system call table generation support mips: remove syscall table entries mips: add +1 to __NR_syscalls in uapi header mips: rename scall64-64.S to scall64-n64.S mips: remove unused macros mips: add __NR_syscalls along with __NR_Linux_syscalls MIPS: Expand MIPS32 ASIDs to 64 bits MIPS: OCTEON: delete redundant register definitions MIPS: OCTEON: cvmx_gmxx_inf_mode: use oldest forward compatible definition MIPS: OCTEON: cvmx_mio_fus_dat3: use oldest forward compatible definition MIPS: OCTEON: cvmx_pko_mem_debug8: use oldest forward compatible definition MIPS: OCTEON: octeon-usb: use common gpio_bit definition MIPS: OCTEON: enable all OCTEON drivers in defconfig mips: annotate implicit fall throughs MIPS: Hardcode cpu_has_mips* where target ISA allows MIPS: MT: Remove norps command line parameter MIPS: Only include mmzone.h when CONFIG_NEED_MULTIPLE_NODES=y ...

| * MIPS: ranchu: Add Ranchu as a new generic-based boardMiodrag Dinic2018-01-221-0/+30

The Ranchu board is intended to be used by Android emulator. The name "Ranchu" originates from Android development community. "Goldfish" and "Ranchu" are terms used for two generations of virtual boards used by Android emulator. The name "Ranchu" is a newer one among the two, and this patch deals with Ranchu. However, for historical reasons, some devices/drivers still contain the name "Goldfish". MIPS Ranchu machine includes a number of Goldfish devices. The support for Virtio devices is also included. Ranchu board supports up to 16 Virtio devices which can be attached using Virtio MMIO Bus. This is summarized in the following picture: ABUS ||----MIPS CPU || | IRQs ||----Goldfish PIC------------(32)-------- || | | | | | | | | | ||----Goldfish TTY------ | | | | | | | | || | | | | | | | | ||----Goldfish RTC-------- | | | | | | | || | | | | | | | ||----Goldfish FB----------- | | | | | | || | | | | | | ||----Goldfish Events--------- | | | | | || | | | | | ||----Goldfish Audio------------ | | | | || | | | | ||----Goldfish Battery------------ | | | || | | | ||----Android PIPE------------------ | | || | | ||----Virtio MMIO Bus | | || | | | | | || | | (virtio-block)--------- | || (16) | | || | (virtio-net)------------------ Device Tree is created on the QEMU side based on the information about devices IO map and IRQ numbers.

| * MIPS: Make CONFIG_MIPS_MT_SMP default yPaul Burton2017-08-305-4/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On systems that support MT ASE multithreading (ie. VPEs) we are very likely to want to include that support as default. Rather than setting it in various defconfigs, simply make CONFIG_MIPS_MT_SMP default y such that systems which select CONFIG_SYS_SUPPORTS_MULTITHREADING get it by default. As well as allowing us to remove the selection of CONFIG_MIPS_MT_SMP from various defconfigs, this also allows the generated generic defconfigs which derive from generic_defconfig to automatically gain support for MT ASE SMP when building for a suitable (pre-MIPSr6) ISA. For malta_kvm_guest_defconfig CONFIG_MIPS_MT_SMP is explicitly disabled since enabling SMP implicitly disables CONFIG_KVM_GUEST, which depends on CONFIG_BROKEN_ON_SMP.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NI 169445 board uses a little endian MIPS32r2 CPU, and therefore including board support in kernels that are unable to run on such a CPU is pointless. Specify requirements in the board config fragment that cause the NI 169445 board support to only be included in generic kernels that target little endian MIPS32r2 CPUs. For example, NI 169445 support will be included when configuring using 32r2el_defconfig but not when using 64r6_defconfig.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MIPS SEAD-3 development board has only ever been used with 32 bit CPUs, so including support for it in 64 bit kernels is wasteful since those kernels will never run on a SEAD-3. Specify a requirement in the SEAD-3 board config fragment that ensures the board support is only included in 32 bit kernels, by checking that CONFIG_32BIT=y.
