commit 207abdb38ee987e99385263e3e56b6c500d74cbc Author: Michal Orzel <michal.orzel@xxxxxxx> AuthorDate: Fri May 6 11:42:24 2022 +0200 Commit: Julien Grall <jgrall@xxxxxxxxxx> CommitDate: Thu May 12 18:33:27 2022 +0100 xen/arm: gnttab: use static inlines for gnttab_{release_}host_mapping* Function unmap_common_complete (common/grant_table.c) defines and sets a variable ld that is later on passed to a macro: gnttab_host_mapping_get_page_type(). On Arm this macro does not make use of any arguments causing a compiler to warn about unused-but-set variable (when -Wunused-but-set-variable is enabled). Fix it by converting this macro to a static inline helper and using the boolean return type. While there, also convert macro gnttab_release_host_mappings.
