2015-03-20staging: panel: remove initialization checkSudip Mukherjee
no need to monitor init_in_progress now as keypad_send_key() can only be called after the timer is initialized. and timer is initialized from keypad_init() which is in the attach section and can only execute after the module has initialized.

2015-03-20staging: panel: return register valueSudip Mukherjee

2015-03-20staging: panel: register rebootSudip Mukherjee
we donot need the reboot notifier in module init section, as the notifier is used after lcd is initialized. so lets register for the reboot notifier only after we have successfully attached to the parallel port. and similarly unregister at detach.

2015-03-20KVM: PPC: Book3S HV: Fix instruction emulationPaul Mackerras
Commit 4a157d61b48c ("KVM: PPC: Book3S HV: Fix endianness of instruction obtained from HEIR register") had the side effect that we no longer reset vcpu->arch.last_inst to -1 on guest exit in the cases where the instruction is not fetched from the guest. This means that if instruction emulation turns out to be required in those cases, the host will emulate the wrong instruction, since vcpu->arch.last_inst will contain the last instruction that was emulated. This fixes it by making sure that vcpu->arch.last_inst is reset to -1 in those cases. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2015-03-20KVM: PPC: Book3S HV: Endian fix for accessing VPA yield countPaul Mackerras
The VPA (virtual processor area) is defined by PAPR and is therefore big-endian, so we need a be32_to_cpu when reading it in kvmppc_get_yield_count(). Without this, H_CONFER always fails on a little-endian host, causing SMP guests to waste time spinning on spinlocks.

2015-03-20KVM: PPC: Book3S HV: Fix spinlock/mutex ordering issue in kvmppc_set_lpcr()Paul Mackerras
Currently, kvmppc_set_lpcr() has a spinlock around the whole function, and inside that does mutex_lock(&kvm->lock). It is not permitted to take a mutex while holding a spinlock, because the mutex_lock might call schedule(). In addition, this causes lockdep to warn about a lock ordering issue: ====================================================== [ INFO: possible circular locking dependency detected ] 3.18.0-kvm-04645-gdfea862-dirty #131 Not tainted ------------------------------------------------------- qemu-system-ppc/8179 is trying to acquire lock: (&kvm->lock){+.+.+.}, at: [<d00000000ecc1f54>] .kvmppc_set_lpcr+0xf4/0x1c0 [kvm_hv] but task is already holding lock: (&(&vcore->lock)->rlock){+.+...}, at: [<d00000000ecc1ea0>] .kvmppc_set_lpcr+0x40/0x1c0 [kvm_hv] which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (&(&vcore->lock)->rlock){+.+...}: [<c000000000b3c120>] .mutex_lock_nested+0x80/0x570 [<d00000000ecc7a14>] .kvmppc_vcpu_run_hv+0xc4/0xe40 [kvm_hv] [<d00000000eb9f5cc>] .kvmppc_vcpu_run+0x2c/0x40 [kvm] [<d00000000eb9cb24>] .kvm_arch_vcpu_ioctl_run+0x54/0x160 [kvm] [<d00000000eb94478>] .kvm_vcpu_ioctl+0x4a8/0x7b0 [kvm] [<c00000000026cbb4>] .do_vfs_ioctl+0x444/0x770 [<c00000000026cfa4>] .SyS_ioctl+0xc4/0xe0 [<c000000000009264>] syscall_exit+0x0/0x98 -> #0 (&kvm->lock){+.+.+.}: [<c0000000000ff28c>] .lock_acquire+0xcc/0x1a0 [<c000000000b3c120>] .mutex_lock_nested+0x80/0x570 [<d00000000ecc1f54>] .kvmppc_set_lpcr+0xf4/0x1c0 [kvm_hv] [<d00000000ecc510c>] .kvmppc_set_one_reg_hv+0x4dc/0x990 [kvm_hv] [<d00000000eb9f234>] .kvmppc_set_one_reg+0x44/0x330 [kvm] [<d00000000eb9c9dc>] .kvm_vcpu_ioctl_set_one_reg+0x5c/0x150 [kvm] [<d00000000eb9ced4>] .kvm_arch_vcpu_ioctl+0x214/0x2c0 [kvm] [<d00000000eb940b0>] .kvm_vcpu_ioctl+0xe0/0x7b0 [kvm] [<c00000000026cbb4>] .do_vfs_ioctl+0x444/0x770 [<c00000000026cfa4>] .SyS_ioctl+0xc4/0xe0 [<c000000000009264>] syscall_exit+0x0/0x98 other info that might help us debug this: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&(&vcore->lock)->rlock); lock(&kvm->lock); lock(&(&vcore->lock)->rlock); lock(&kvm->lock); *** DEADLOCK *** 2 locks held by qemu-system-ppc/8179: #0: (&vcpu->mutex){+.+.+.}, at: [<d00000000eb93f18>] .vcpu_load+0x28/0x90 [kvm] #1: (&(&vcore->lock)->rlock){+.+...}, at: [<d00000000ecc1ea0>] .kvmppc_set_lpcr+0x40/0x1c0 [kvm_hv] stack backtrace: CPU: 4 PID: 8179 Comm: qemu-system-ppc Not tainted 3.18.0-kvm-04645-gdfea862-dirty #131 Call Trace: [c000001a66c0f310] [c000000000b486ac] .dump_stack+0x88/0xb4 (unreliable) [c000001a66c0f390] [c0000000000f8bec] .print_circular_bug+0x27c/0x3d0 [c000001a66c0f440] [c0000000000fe9e8] .__lock_acquire+0x2028/0x2190 [c000001a66c0f5d0] [c0000000000ff28c] .lock_acquire+0xcc/0x1a0 [c000001a66c0f6a0] [c000000000b3c120] .mutex_lock_nested+0x80/0x570 [c000001a66c0f7c0] [d00000000ecc1f54] .kvmppc_set_lpcr+0xf4/0x1c0 [kvm_hv] [c000001a66c0f860] [d00000000ecc510c] .kvmppc_set_one_reg_hv+0x4dc/0x990 [kvm_hv] [c000001a66c0f8d0] [d00000000eb9f234] .kvmppc_set_one_reg+0x44/0x330 [kvm] [c000001a66c0f960] [d00000000eb9c9dc] .kvm_vcpu_ioctl_set_one_reg+0x5c/0x150 [kvm] [c000001a66c0f9f0] [d00000000eb9ced4] .kvm_arch_vcpu_ioctl+0x214/0x2c0 [kvm] [c000001a66c0faf0] [d00000000eb940b0] .kvm_vcpu_ioctl+0xe0/0x7b0 [kvm] [c000001a66c0fcb0] [c00000000026cbb4] .do_vfs_ioctl+0x444/0x770 [c000001a66c0fd90] [c00000000026cfa4] .SyS_ioctl+0xc4/0xe0 [c000001a66c0fe30] [c000000000009264] syscall_exit+0x0/0x98 This fixes it by moving the mutex_lock()/mutex_unlock() pair outside the spin-locked region.
