Hi,
This is v4 of "memblock: make memblock_find_in_range method private" patch
that essentially replaces memblock_find_in_range() + memblock_reserve()
calls with equivalent calls to memblock_phys_alloc() and prevents usage of
memblock_find_in_range() outside memblock itself.
The patch uncovered an issue with top down memory mapping on x86 and this
version has a preparation patch that addresses this issue.
Guenter, I didn't add your Tested-by because the patch that addresses the
crashes differs from the one you've tested.
v4:
* Add patch that prevents the crashes reported by Guenter Roeck on x86/i386
on QEMU with 256M or 512M of memory and EFI boot enabled.
* Add Acked-by and Reviewed-by, thanks everybidy!
v3: https://lore.kernel.org/lkml/20210803064218.6611-1-rppt@kernel.org
* simplify check for exact crash kerenl allocation on arm, per Rob
* make crash_max unsigned long long on arm64, per Rob
v2: https://lore.kernel.org/lkml/20210802063737.22733-1-rppt@kernel.org
* don't change error message in arm::reserve_crashkernel(), per Russell
v1: https://lore.kernel.org/lkml/20210730104039.7047-1-rppt@kernel.org
