The driver was checking for non-NULL address.
- adapter->napi[i]
This is pointless as these will be always non-NULL, since the
'dapter->napi' is allocated in init_napi().
It is safe to get rid of useless checks for addresses to fix the

The bamboo dts has a bug: it uses a non-naturally aligned range
for PCI memory space. This isnt' supported by the code, thus
causing PCI to break on this system.
This is due to the fact that while the chip memory map has 1G
re
BookE and 40x processors lack the MSR:RI bit. However, we have a
few common code places that rely on it.
This fixes it by not defining MSR_RI on those processor types and
using the appropriate ifdef's in those locations.

For this use case, completions and semaphores are equivalent,
but semaphores are an awkward interface that should generally

The PPC mobility code receives RTAS requests to delete nodes with
platform-/hardware-specific attributes when restarting the kernel
after a migration. My example is for migration between a P8 Alpine
and a P8 Brazos. Nodes to be deleted include 'ibm,random-v1',
'ibm,platform-facilities', 'ibm,sym

ibmvnic_reset can create and schedule a reset work item from

the reset work item mutex to a spin lock. Locking debugger generated

This patch set fixes issues with scheduling reset work items in
a tasklet context. Since ibmvnic_reset can called in an interrupt,
it should not use a mutex or allocate memory non-atomically.

Add debugfs interface to retrieve associativity information for lpar
vcpus (debugfs/vphn/lpar) and the hypervisor cpus (debugfs/vphn/hyp).
This information is useful to derive various metrics, including the vcpu
dispatch statistics in a SPLPAR environment.

arch/p
H_HOME_NODE_ASSOCIATIVITY hcall can take two different flags and return
different associativity information in each case. Generalize the
existing hcall_vphn() function to take flags as an argument and to
return the result. Update the only existing user to pass the proper
arguments.
Signed-off-by:
This is an alternate way to provide statistics around vcpu dispatches in
a SPLPAR environment. By obtaining access to the VPHN information, and
in concert with the existing debugfs dtl interface, we can derive
different statistics related to how vcpus are dispatched by the
hypervisor.

When the watchdog timer is set in interrupt mode, it causes a
machine check when it times out. The purpose of this mode is to

This patch implements a special handling for that, in order to not

It also warns about DMA on stack when CONFIG_HAVE_ARCH_VMAP_STACK is
selected. It will help locate them before activating CONFIG_VMAP_STACK
