Subject: [PATCH V6 00/22] arch: Add basic LoongArch support
LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V.
LoongArch includes a reduced 32-bit version (LA32R), a standard 32-bit
version (LA32S) and a 64-bit version (LA64). LoongArch use ACPI as its
boot protocol LoongArch-specific interrupt controllers (similar to APIC)
are already added in the next revision of ACPI Specification (current
revision is 6.4).
This patchset is adding basic LoongArch support in mainline kernel, we
can see a complete snapshot here:
https://github.com/loongson/linux/tree/loongarch-next
Cross-compile tool chain to build kernel:
https://github.com/loongson/build-tools/releases/latest/download/loongarch64-clfs-20211202-cross-tools.tar.xz
A CLFS-based Linux distro:
https://github.com/loongson/build-tools/releases/latest/download/loongarch64-clfs-system-2021-12-02.tar.bz2
Open-source tool chain which is under review (Binutils is already upstream):
https://github.com/loongson/binutils-gdb/tree/loongarch-2_37
https://github.com/loongson/gcc/tree/loongarch-12
https://github.com/loongson/glibc/tree/loongarch_2_34_dev
Loongson and LoongArch documentations:
https://github.com/loongson/LoongArch-Documentation
LoongArch-specific interrupt controllers:
https://mantis.uefi.org/mantis/view.php?id=2203
V1 -> V2:
1, Add documentation patches;
2, Restore copyright statements;
3, Split the big header patch;
4, Cleanup signal-related headers;
5, Cleanup incomplete 32-bit support;

11, Simplify the VDSO/VSYSCALL implementation;
12, Use generic I/O access macros and functions;
13, Remove unaligned access emulation at present;
14, Keep clocksource code in arch since it is the "native clocksource";
15, Some other minor fixes and improvements.
V2 -> V3:
1, Rebased on 5.15-rc1;
2, Cleanup PCI code on V2;
3, Support multiple msi domain;
4, Support cacheable ioremap();
5, Use irq stack for interrupt handling;
6, Adjust struct ucontext and rt_sigframe;
7, Some other minor fixes and improvements.
V3 -> V4:
1, Rebased on 5.15-rc3;
2, Rework SMP support and remove legacy IPI;
3, Rework signal support and remove loongarch_abi;
4, Simplify phys_to_dma() and dma_to_phys();
5, Remove unused sys_mmap2() implementation;
6, Remove unused strncpy_user.S and strnlen_user.S;
7, Some other minor fixes and improvements.
V4 -> V5:
1, Rebased on 5.15-rc4;
2, Fix a _PAGE_CHG_MASK bug;
3, Fix vdso_base() calculation;
4, Adjust syscall and ptrace code;
5, Use generic bitops implementation;
6, Avoid syscall restart handling in sys_rt_sigreturn();
7, Update commit messages.
V5 -> V6:
1, Rebased on 5.16-rc2;
2, Use GENERIC_IRQ_MIGRATION;
3, Improve sigcontext definition;
4, Improve numa_default_distance();
5, Increse MINSIGSTKSZ and SIGSTKSZ;
6, Restruct pt_regs and user_pt_regs;
7, Fix a corner case of protection_map;
8, Fix some corner cases of system calls;
9, Separate module region and vmalloc region;
10, Rename registers to match official documents.
