Problem Description :
PowerPC systems running Ubuntu18.04 have Transparent Huge Pages (THP)
always set to "madvise". It should be by default set to "always".
Reproducible Step:
1- Install Ubuntu 18.04 on PowerPC box
2- cat /sys/kernel/mm/transparent_hugepage/enabled
3- grep "TRANSPARENT" /boot/config-$(uname -r)
it is set to madvise
LOG:
root@system:~# grep "TRANSPARENT" /boot/config-$(uname -r)
CONFIG_HAVE_ARCH_TRANSPARENT_HUGEPAGE=y
CONFIG_TRANSPARENT_HUGEPAGE=y
# CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS is not set
CONFIG_TRANSPARENT_HUGEPAGE_MADVISE=y
CONFIG_TRANSPARENT_HUGE_PAGECACHE=y
