This patch series enables kdump support for kexec_file_load system
call (kexec -s -p) on PPC64. The changes are inspired from kexec-tools
code but heavily modified for kernel consumption. There is scope to
expand purgatory to verify sha256 digest along with other improvements
in purgatory code. Wil

Some architectures may have special memory regions, within the given
memory range, which can't be used for the buffer in a kexec segment.
Implement weak arch_kexec_locate_mem_hole() definition which arch code
may override, to take care of special regions, while trying to locate
a memory hole.
Also
Some of the kexec_file_load code isn't PPC64 specific. Move PPC64
specific code from kexec/file_load.c to kexec/file_load_64.c. Also,
rename purgatory/trampoline.S to purgatory/trampoline_64.S in the
same spirit.

In kexec case, the kernel to be loaded uses the same memory layout as
the running kernel. So, passing on the DT of the running kernel would
be good enough.
But in case of kdump, different memory ranges are needed to manage
loading the kdump kernel, booting into it and exporting the elfcore
of the
Currently, numa & prom are the users of drmem lmb walk code. Loading
kdump with kexec_file also needs to walk the drmem LMBs to setup the
usable memory ranges for kdump kernel. But there are couple of issues
in using the code as is. One, walk_drmem_lmb() code is built into the
.init section current
Kdump kernel, used for capturing the kernel core image, is supposed
to use only specific memory regions to avoid corrupting the image to
be captured. The regions are crashkernel range - the memory reserved
explicitly for kdump kernel, memory used for the tce-table, the OPAL
region and RTAS region a
crashkernel region could have an overlap with special memory regions
like opal, rtas, tce-table & such. These regions are referred to as
exclude memory ranges. Setup this ranges during image probe in order
to avoid them while finding the buffer for different kdump segments.
Override arch_kexec_loc
Right now purgatory implementation is only minimal. But if purgatory
code is to be enhanced to copy memory to the backup region and verify
sha256 digest, relocations may have to be applied to the purgatory.
So, add support to relocate purgatory in kexec_file_load system call
by setting up TOC point
To avoid any weird errors, the purgatory should run with its own
stack. Set one up by adding the stack buffer to .data section of
the purgatory. Also, setup opal base & entry values in r8 & r9
registers to help early OPAL debugging.

Though kdump kernel boots from loaded address, the first 64K bytes

Prepare elf headers for the crashing kernel's core file using
crash_prepare_elf64_headers() and pass on this info to kdump
kernel by updating its command line with elfcorehdr parameter.
Also, add elfcorehdr location to reserve map to avoid it from
being stomped on while booting.

The kexec purgatory has to run in real mode. Only the first memory
block maybe accessible in real mode. And, unlike the case with panic
kernel, no memory is set aside for regular kexec load. Another thing
to note is, the memory for crashkernel is reserved at an offset of
128MB. So, when crashkernel
While initrd, elfcorehdr and backup regions are already added to the
reserve map, there are a few missing regions that need to be added to
the memory reserve map. Add them here. And now that all the changes
to load panic kernel are in place, claim likewise.

Hi Bartosz,
I love your patch! Yet something to improve:
[auto build test ERROR on iio/togreg]

[cannot apply to xlnx/master]
[If your patch is applied to the wrong git tree, kindly drop us a note.
