if SWAP is disabled in kernel config, the following compile error will raise up
with this release
arch/x86/built-in.o: in function `max_swapfile_size': (.text+0x3bba1):
undefined reference to `generic_max_swapfile_size'
of course this is simple to fix. the function max_swapfile_size must be
excluded if CONFIG_SWAP is disabled
Fixed with upstream commit 792adb90fa72 ("x86/init: fix build with
CONFIG_SWAP=n").
Also needed in other stable branches (at least in 4.4).

This is the start of the stable review cycle for the 4.9.120 release.
There are 107 patches in this series, all will be posted as a response
to this one. If anyone has any issues with these being applied, please
let me know.
Responses should be made by Thu Aug 16 17:14:53 UTC 2018.
Anything received after that time might be too late.
The whole patch series can be found in one patch at:
https://www.kernel.org/pub/linux/kernel/v4.x/stable-review/patch-4.9.120-rc1.gz
or in the git tree and branch at:
