Hi Laurent, What is your plan for this patch? Technically this is a bugfix.

I see the code was released for 6.0, so not a regression.

Linux Hexagon port doesn't define a specific 'struct stat' but uses the generic one (see Linux commit 6103ec56c65c [*] "asm-generic: add generic ABI headers" which predates the introduction of the Hexagon port). Remove the target specific target_stat (which in fact is the target_stat64 structure but uses incorrect target_long and ABI unsafe long long types) and use the generic target_stat64 instead.
