[TLDR: I'm adding the regression report below to regzbot, the Linux kernel regression tracking bot; all text you find below is compiled from a few templates paragraphs you might have encountered already already from similar mails.]
Hi, this is your Linux kernel regression tracker. Sending this just to the lists, as it's already handled.

To be sure below issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression tracking bot:
#regzbot ^introduced f5ff79fddf0e #regzbot title dma: "dma-mapping: remove CONFIG_DMA_REMAP" causes AMD SME boot fail #regzbot ignore-activity
If it turns out this isn't a regression, free free to remove it from the tracking by sending a reply to this thread containing a paragraph like "#regzbot invalid: reason why this is invalid" (without the quotes).
Ciao, Thorsten
