Subject: [next] arm64: juno-r2: BUG: KASAN: use-after-free in __pci_enable_msi_range
While booting Linux next 20211215 and next 20211217 on arm64 juno-r2 device
the following kernel crash reported and several LTP syscalls test cases,
Only noticed on juno-r2 whereas dragonboard-410c and hikey-hi6220 tests pass.
Test case failure:
add_key05.c:207: TBROK: Failed to open FILE
'/proc/sys/kernel/keys/gc_delay' for writing: ENOENT (2)
tst_taint.c:15: TBROK: Failed to open FILE '/proc/sys/kernel/tainted'
for reading: ENOENT (2)
tst_pid.c:43: TBROK: Failed to open FILE '/proc/sys/kernel/pid_max'
for reading: ENOENT (2)
arm64 juno-r2 kernel crash log while booting.
