Re: [RESEND PATCH v2 0/5] target/riscv: Support RISC-V privilege 1.13 spec

[Daniel Henrique Barboza]

Fea,

Please try to also add all RISC-V QEMU maintainers and reviewers when sending
patches. It will get your patches reviewed and queued faster. Otherwise the
maintainers can miss you your series due to high ML traffic.

You can fetch who you want to CC using the get_maintainer.pl script with the
patch files or any source file in particular, e.g.:

$ ./scripts/get_maintainer.pl -f target/riscv/cpu.c
Palmer Dabbelt <palmer@dabbelt.com> (supporter:RISC-V TCG CPUs)
Alistair Francis <alistair.francis@wdc.com> (supporter:RISC-V TCG CPUs)
Bin Meng <bmeng.cn@gmail.com> (supporter:RISC-V TCG CPUs)
Weiwei Li <liwei1518@gmail.com> (reviewer:RISC-V TCG CPUs)
Daniel Henrique Barboza <dbarboza@ventanamicro.com> (reviewer:RISC-V TCG CPUs)
Liu Zhiwei <zhiwei_liu@linux.alibaba.com> (reviewer:RISC-V TCG CPUs)
qemu-riscv@nongnu.org (open list:RISC-V TCG CPUs)
qemu-devel@nongnu.org (open list:All patches CC here)


I added the extra folk in the CC for this reply so don't worry about it.


Alistair, please queue this series. It's already fully acked and I would like 
to add
some bits on top of the priv_spec 1.13 support.


Thanks,


Daniel
