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
root@system:~# cat /sys/kernel/mm/transparent_hugepage/enabled
always [madvise] never
root@system:~#
