commit a2e8d64c803371b84b2bbb18a7b1c0a8b9d8142b Author: Federico Serafini <federico.serafini@xxxxxxxxxxx> AuthorDate: Fri Nov 10 09:50:13 2023 +0100 Commit: Stefano Stabellini <stefano.stabellini@xxxxxxx> CommitDate: Fri Nov 17 18:07:26 2023 -0800 xen/string: address violations of MISRA C:2012 Rules 8.2 and 8.3 Add missing parameter names to address violations of MISRA C:2012 Rule 8.2. Resolve mismatches between parameter name "count" used in "xen/lib/mem{cpy,move,set}.c" and parameter name "n" used in "xen/arch/x86/string.c" to address violations of MISRA C:2012 Rule 8.3. No functional change.
