Ard Biesheuvel 8a5b403d71 arm64, mm, efi: Account for GICv3 LPI tables in static memblock reserve table ... In the irqchip and EFI code, we have what basically amounts to a quirk to work around a peculiarity in the GICv3 architecture, which permits the system memory address of LPI tables to be programmable only once after a CPU reset. This means kexec kernels must use the same memory as the first kernel, and thus ensure that this memory has not been given out for other purposes by the time the ITS init code runs, which is not very early for secondary CPUs. On systems with many CPUs, these reservations could overflow the memblock reservation table, and this was addressed in commit: eff8962888 ("efi/arm: Defer persistent reservations until after paging_init()") However, this turns out to have made things worse, since the allocation of page tables and heap space for the resized memblock reservation table itself may overwrite the regions we are attempting to reserve, which may cause all kinds of corruption, also considering that the ITS will still be poking bits into that memory in response to incoming MSIs. So instead, let's grow the static memblock reservation table on such systems so it can accommodate these reservations at an earlier time. This will permit us to revert the above commit in a subsequent patch.
