Subject: [PATCH] x86/tsc: Prevent NULL pointer deref in
|
||||
calibrate_delay_is_known()
|
||||
|
||||
The topology_core_cpumask is used to find a neighbour cpu in
|
||||
calibrate_delay_is_known(). It might not be allocated at the first invocation
|
||||
of that function on the boot cpu, when CONFIG_CPUMASK_OFFSTACK is set.
|
||||
|
||||
The mask is allocated later in native_smp_prepare_cpus. As a consequence the
|
||||
underlying find_next_bit() call dereferences a NULL pointer.
|
||||
|
||||
Add a proper check to prevent this.

||||

||||
