disable loading f2fs module on PAGE_SIZE > 4KB
[ Upstream commit 4071e67cffcc5c2a007116a02437471351f550eb ]
The following patch disables loading of f2fs module on architectures
which have PAGE_SIZE > 4096 , since it is impossible to mount f2fs on
such architectures , log messages are:
mount: /mnt: wrong fs type, bad option, bad superblock on
/dev/vdiskb1, missing codepage or helper program, or other error.
/dev/vdiskb1: F2FS filesystem,
UUID=1d8b9ca4-2389-4910-af3b-10998969f09c, volume name ""
May 15 18:03:13 ttip kernel: F2FS-fs (vdiskb1): Invalid
page_cache_size (8192), supports only 4KB

which was introduced by git commit 5c9b469295fb6b10d98923eab5e79c4edb80ed20
tested on git kernel 4.17.0-rc6-00309-gec30dcf7f425
with patch applied:
