The patch titled

This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Jérémy Lefaure <jeremy.lefaure@xxxxxxxxxxxx>
Subject: shmem: fix compilation warnings on unused functions
Compiling shmem.c with CONFIG_SHMEM and CONFIG_TRANSAPRENT_HUGE_PAGECACHE
enabled raises warnings on two unused functions when CONFIG_TMPFS and
CONFIG_SYSFS are both disabled:
mm/shmem.c:390:20: warning: `shmem_format_huge' defined but not used
[-Wunused-function]
static const char *shmem_format_huge(int huge)
^~~~~~~~~~~~~~~~~
mm/shmem.c:373:12: warning: `shmem_parse_huge' defined but not used
[-Wunused-function]
static int shmem_parse_huge(const char *str)
^~~~~~~~~~~~~~~~
A conditional compilation on tmpfs or sysfs removes the warnings.
