Subject: [PATCH v1 0/6] Allow kexec reboot for GICv3 and device tree
Marc Zyngier added the support for kexec and GICv3 for EFI based systems.
However, it is still not possible todo on systems with device trees.
Here is EFI fixes from Marc:
https://lore.kernel.org/lkml/20180921195954.21574-1-marc.zyngier@arm.com
For Device Tree variant: lets allow reserve a memory region in interrupt
controller node, and use this property to allocate interrupt tables.
This way we are safe during kexec, as these page tables are going to stay
the same after kexec.
Pavel Tatashin (6):
rqchip/gic-v3-its: reset prop table outside of allocation
rqchip/gic-v3-its: use temporary va / pa variables
rqchip/gic-v3-its: add reset pending table function
rqchip/gic-v3-its: move reset pending table outside of allocator
rqchip/gic-v3-its: move reset pending table outside of allocator
dt-bindings: interrupt-controller: add optional memory-region
