[PATCH] x86: allow i386 kexec to load x86_64 bzImage anywhere

2021-08-06 Thread Kevin Mitchell
In linux-5.2, the following commit allows the kdump kernel to be loaded at a higher address than 896M 9ca5c8e632ce ("x86/kdump: Have crashkernel=X reserve under 4G by default") While this limit does indeed seem unnecessary for x86_64 kernels, it still is required to boot to or from i386 kernels.
