Because we only can isolate a active page via isolate_huge_page()
and hugetlbfs_fallocate() forget to mark it as active, we cannot
isolate and migrate those pages.
Only export set_page_huge_active, just leave clear_page_huge_active

The page_huge_active() can be called from scan_movable_pages() which

I would call out the problem more explicitly.
Hello John, Joel, Jae,
For this should be set LCLK to be CRITICAL it will fix LPC related
driver. (KCS/BT/SNOOP)
I have send the patch before.
https://patchwork.ozlabs.org/project/linux-aspeed/patch/20200928070108.14040-2-ryan_c...@aspeedtech.com/
Hello Joel,
Allow the overlays to have .dtbo extension instead of just .dtb. This
allows them to be identified easily by tools as well as humans.
Allow the dtbo outform in dtc.c for the same.

Hello,
syzbot found the following issue on:
HEAD commit:6207214a Merge tag 'afs-fixes-04012021' of git://git.kerne..

Just to note I have also reproduced this on a 5.10.0 kernel.

We will start building overlays for platforms soon in the kernel and
would need these tools going forward. Lets fetch and build these.
Note that a copy of fdtdump.c was already copied back in the year 2012,
but it was never updated or built for some reason.

Syzbot discovered that the probe error handling doesn't clean up the
resources allocated in zr364xx_board_init(). There are several
related bugs in this code so I have re-written the error handling.
1) Introduce a new function zr364xx_board_uninit() which cleans up
the resources in
