[PATCH 0/6] mm: some config cleanups

[Anshuman Khandual]

This series contains config cleanup patches which reduces code duplication
across platforms and also improves maintainability. There is no functional
change intended with this series. This has been boot tested on arm64 but
only build tested on some other platforms.

This applies on 5.12-rc2

[PATCH 3/6] mm: Generalize ARCH_ENABLE_MEMORY_[HOTPLUG|HOTREMOVE]

[Anshuman Khandual]

ARCH_ENABLE_MEMORY_[HOTPLUG|HOTREMOVE] configs have duplicate definitions
on platforms that subscribe them. Instead, just make them generic options
which can be selected on applicable platforms.

Again the same thing happened.

From past experiences, this problem might be just related to many
entries on the CC list. But this time even dropped the --cc-cover
parameter which would have expanded the CC list on each individual
patches further, like last time.

If it helps, have hosted these six patches on v5.12-rc2

Seems like there was a problem during the email because some patches
might not have hit the mailing list. Although git send-email never
really reported any problem. Not sure what happened here.

https://patchwork.kernel.org/project/linux-mm/list/?series=443619
https://lore.kernel.org/linux-mm/1615185706-24342-1-git-send-email-anshuman.khandual@arm.com/

Will probably resend the series.

[PATCH 0/6] mm: some config cleanups

[Anshuman Khandual]

This series contains config cleanup patches which reduces code duplication
across platforms and also improves maintainability. There is no functional
change intended with this series. This has been boot tested on arm64 but
only build tested on some other platforms.

This applies on 5.12-rc2
