7e99a6ba69 target: disable CONFIG_PROC_PAGE_MONITOR on most targets
Disable CONFIG_PROC_PAGE_MONITOR in most places and only keep it enabled
for virtual targets such as malta or potent ones like x86.

This saves up to 4KB of uncompressed kernel size and significantly
decreases CPU load under certain workloads.

110c9e9034 layerscape: update config-4.9
Some new options were introduced by kernel patches.
And some options should be removed/added.
The config-4.9 should be updated accordingly.

c08293893a kernel: add support for limiting 4K erase sector support based on flash chip size
Some targets need 4K sectors for small flash chips (e.g. some
routerboards, where the entire chip is just one "erase block"), whereas
on other devices 4K sectors lead to horrible flash erase/write
performance.

Set the default limit in the generic kernel configuration to 4 MiB to
ensure that all new platforms don't use 4K sectors for bigger flash
chips. On all existing targets use 16 MiB for now to avoid regressions.
They will be changed individually in follow-up commits.

cf17e034bc kernel: Add some more generic config options
These options are deactivating some kernel modules for IP blocks not
uses on this SoC. I saw the same when working with the ARM64 Marvell
board so it is better to move them to generic.
