Kindly ping.
Could anyone give some feedback? Thanks.

Dear team,
The following patch set is intended to support DPDK running on LoongArch
architecture.
LoongArch is the general processor architecture of Loongson Corporation
and is a new RISC ISA, which is a bit like MIPS or RISC-V.
The online documents of LoongArch architecture are here:
https://loongson.github.io/LoongArch-Documentation/README-EN.html
The latest build tools for LoongArch (binary) can be downloaded from:
https://github.com/loongson/build-tools
v6:
- place some blocks for LoongArch in a pseudo alphabetical order
- remove some macros not used
- update release notes in the correct format
- remove some headers for LoongArch, including msclock, pflock and
ticketlock, which are now non-arch specific
- rename some helpers to make them more readable
- remove some copied comments
- force-set RTE_FORCE_INTRINSICS in config and remove non-arch
specific implementations
- fix format errors in meson file reported by check-meson.py
- rebase the patchset on the main repository
v5:
- merge all patches for supporting LoongArch EAL into one patch
- add LoongArch cross compilation document and update some documents
related to architecture
- remove vector stubs added for LoongArch in net/i40e and net/ixgbe
- add LOONGARCH64 cross compilation job in github ci
v4:
- rebase the patchset on the main repository of version 22.07.0
v3:
- add URL for cross compile tool chain
- remove rte_lpm_lsx.h which was a dummy vector implementation
because there is already a scalar implementation, thanks to
Michal Mazurek
- modify the name of compiler for cross compiling
- remove useless variable in meson.build
v2:
- use standard atomics of toolchain to implement
atomic operations
- implement spinlock based on standard atomics
*** BLURB HERE ***

net/memif: set memfd syscall ID on LoongArch
net/tap: set BPF syscall ID for LoongArch
examples/l3fwd: enable LoongArch operation
test/cpuflags: add test for LoongArch cpu flag
