Hi,
Greg or Sasha won't know what to do with this. Not sure who follows the stable list either. Quentin sent the patch, but is not the author. Given the patch in question is about consistency between EFI memory map boot and DT memory map boot, copying EFI knowledgeable folks would help (Ard B for starters).
Ok thanks for the tips. I add Ard in the loop.
Sigh. If it was only Ard I was suggesting I would have done that myself. Now everyone on the patch in question and relevant lists are Cc'ed.
Thanks for the cc.
Ard, let me know if other people have to be directly added or if I have to resend to another mailing list.
thanks alex
Since v5.4.102 I observe a regression on stm32mp1 platform: "no-map" reserved-memory regions are no more "reserved" and make part of the kernel System RAM. This causes allocation failure for devices which try to take a reserved-memory region.
It has been introduced by the following path:
"fdt: Properly handle "no-map" field in the memory region [ Upstream commit 86588296acbfb1591e92ba60221e95677ecadb43 ]" which replace memblock_remove by memblock_mark_nomap in no-map case.
Why was this backported? It doesn't look like a bugfix to me.
Probably because of commit 8a5a75e5e9e5 ("of/fdt: Make sure no-map does not remove already reserved regions") which was in the same series.
'Properly handle' implies before it was 'improperly handled', so sounds like a fix.
