Subject: [PATCH v2 1/4] Documentation: riscv: uabi: Clarify ISA spec
 version for canonical order

Specify that chapter 27 refers to version 20191213 of the RISC-V ISA
Unprivileged Architecture. The chapter numbering differs across
specification versions - for example, in version 20250508, the ISA
Extension Naming Conventions is chapter 36, not chapter 27.

Historical versions of the RISC-V specification can be found via Link [1].

 ------------------------------------
 
 The canonical order of ISA extension names in the ISA string is defined in
-chapter 27 of the unprivileged specification.
+Chapter 27 of the RISC-V Instruction Set Manual Volume I Unprivileged ISA
+(Document Version 20191213).

 The specification uses vague wording, such as should, when it comes to ordering,
 so for our purposes the following rules apply:
