[Crash-utility] arm64: doesn't work for kernel v5.4?

Hi Dave, I tried to use crash v7.2.7 with kernel v5.4-rc1 on arm64. 1. VA_BITS_ACTUAL is missing in vmcoreinfo. Does anyone work on fixing it on kernel side? (just adding one or two lines though) 2. With a tweak above, I still fail to run crash with vmcore seeing the following errors; (I didn't dig into details) crash-arm64: invalid kernel virtual address: ffff800010c689a8 type: "kernel_config_data" WARNING: cannot read kernel_config_data crash-arm64: invalid kernel virtual address: ffff80001177a160 type: "possible" WARNING: cannot read cpu_possible_map crash-arm64: invalid kernel virtual address: ffff80001177a140 type: "present" WARNING: cannot read cpu_present_map crash-arm64: invalid kernel virtual address: ffff80001177a120 type: "online" WARNING: cannot read cpu_online_map crash-arm64: invalid kernel virtual address: ffff80001177a188 type: "active" WARNING: cannot read cpu_active_map crash-arm64: invalid kernel virtual address: ffff80001196afe0 type: "shadow_timekeeper xtime_sec" crash-arm64: invalid kernel virtual address: ffff800011782b3c type: "init_uts_ns" WARNING: invalid linux_banner pointer: ffff800010c500e8 crash: vmlinux.1003 and vmcore.1003 do not match! Have you noticed this issue? Thanks, -Takahiro Akashi
