intel-ixp42x-welltech-epbx100 no longer boot due to 463dbba4d189 ("ARM: 9104/2: Fix Keystone 2 kernel mapping regression")

Hello

I am working on puting my ixp4xx board on kernelCI.
But it no longer boot since 4.14.
It only prints "Starting kernelUncompressing Linux... done, booting the kernel." then nothing.

I bisected the break to 463dbba4d189 ("ARM: 9104/2: Fix Keystone 2 kernel mapping regression")

With this patch reverted on top of 4.14, 5.15-rc3 and next-20210927, the board boot successfully.

Regards
