[jdk17u-dev] RFR: 8312394: [linux] SIGSEGV if kernel was built without hugepage support

Wed Aug 30 09:21:32 UTC 2023

Clean backport (based on https://github.com/openjdk/jdk17u-dev/pull/1694). Fixes a crash post-8310233 on obscure Linux kernels (compiled without huge page support, typically for SBCs). We saw it on arm32 on Raspian OS.
