Stephen Boyd fcc16882ac lib: atomic64: Initialize locks statically to fix early users ... The atomic64 library uses a handful of static spin locks to implement atomic 64-bit operations on architectures without support for atomic 64-bit instructions. Unfortunately, the spinlocks are initialized in a pure initcall and that is too late for the vfs namespace code which wants to use atomic64 operations before the initcall is run. This became a problem as of commit 8823c079ba: "vfs: Add setns support for the mount namespace". This leads to BUG messages such as: BUG: spinlock bad magic on CPU#0, swapper/0/0 lock: atomic64_lock+0x240/0x400, .magic: 00000000, .owner: <none>/-1, .owner_cpu: 0 do_raw_spin_lock+0x158/0x198 _raw_spin_lock_irqsave+0x4c/0x58 atomic64_add_return+0x30/0x5c alloc_mnt_ns.clone.14+0x44/0xac create_mnt_ns+0xc/0x54 mnt_init+0x120/0x1d4 vfs_caches_init+0xe0/0x10c start_kernel+0x29c/0x300 coming out early on during boot when spinlock debugging is enabled. Fix this by initializing the spinlocks statically at compile time. Reported-and-tested-by: Vaibhav Bedia <vaibhav.bedia@ti.com> Tested-by: Tony Lindgren <tony@atomide.com> Cc: Eric W.
