These two patches are upstream already. A third patch is also upstream, but it is not needed with the older RPM we have, so I didn't include it.

Subject: [PATCH 2/3] rpmrc: Convert uname.machine == "riscv" to
|
|
"riscv32"/"riscv64"/"riscv128".
|
|
|
|
On RISC-V, the kernel can return uname.machine == "riscv" (for all bit
|
|
sizes). I say "can" return, because that is the default, but it is
|
|
also possible to compile the kernel specially so it returns "riscv64"
|
|
etc.
|
|
|
|
GNU is using "riscv64".
|
|
|
|
This commit converts the kernel uname machine type "riscv" to a more
|
|
suitable value.
|
|
|
|
This conversion is supposed to be done by the arch_canon table.
|
|
However the arch_canon table is not populated until after the
|
|
defaultMachine function is called for the first time, making it a bit
|
|
useless. In any case, arch_canon cannot take into account the bit
|
|
size of the architecture, but the C code here can.
