The patch titled Subject: hugetlb: fix hugepages= entry in kernel-parameters.txt has been removed from the -mm tree. Its filename was hugetlb-fix-hugepages=-entry-in-kernel-parameterstxt.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Luiz Capitulino <lcapitulino@xxxxxxxxxx> Subject: hugetlb: fix hugepages= entry in kernel-parameters.txt The hugepages= entry in kernel-parameters.txt states that 1GB pages can only be allocated at boot time and not freed afterwards. This is not true since commit 944d9fec8d7aee, at least for x86_64. Instead of adding arch-specifc observations to the hugepages= entry, this commit just drops the out of date information. Further information about arch-specific support and available features can be obtained in the hugetlb documentation.
