The data structure (i.e struct imc_mem_info) to hold the memory address
information for nest imc units is allocated based on the number of nodes
in the system.
nest_imc_event_init() traverse this struct array to calculate the memory

Thanks, patch applied to my kvm-ppc-next branch.

The dma_direct_supported() function intends to check the DMA mask against
specific values. However, the phys_to_dma() function includes the SME
encryption mask, which defeats the intended purpose of the check. This
results in drivers that support less than 48-bit DMA (SME encryption mask
is bit
If the device tree doesn't reside in the memory which is declared
inside it, it has to be moved as well as this memory will not be
mapped by the kernel.

Hi Darren,
I guess in general we'd like more of this to come from the device tree.
But I'll merge this series as-is, because I don't think it helps anyone
to have this code out-of-tree. We can always clean things up further in

System call table generation script must be run to gener-
ate unistd_32/64.h and syscall_table_32/64/c32/spu.h files.
This patch will have changes which will invokes the script.
This patch will generate unistd_32/64.h and syscall_table-
_32/64/c32/spu.h files by the syscall table generation
PowerPC uses a syscall table with native and compat calls
interleaved, which is a slightly simpler way to define two
matching tables.
As we move to having the tables generated, that advantage
is no longer important, but the interleaved table gets in
the way of using the same scripts as on the
The system call tables are in different format in all
architecture and it will be difficult to manually add or
modify the system calls in the respective files. To make
it easy by keeping a script and which will generate the
uapi header and syscall table file. This change will also
help to unify
Move the macro definition for compat_sys_sigsuspend from
asm/systbl.h to the file which it is getting included.
One of the patch in this patch series is generating uapi
header and syscall table files. In order to come up with
a common implimentation across all architecture, we need
to do this
NR_syscalls macro holds the number of system call exist
in powerpc architecture. We have to change the value of
NR_syscalls, if we add or delete a system call.
One of the patch in this patch series has a script which
will generate a uapi header based on syscall.tbl file.

The purpose of this patch series is, we can easily
add/modify/delete system call table support by cha-
nging entry in syscall.tbl file instead of manually
changing many files. The other goal is to unify the

Non-overlay dynamic devicetree node removal may leave the node in
the phandle cache. Subsequent calls to of_find_node_by_phandle()
will incorrectly find the stale entry. Remove the node from the
cache.
Add paranoia checks in of_find_node_by_phandle() as a second level
of
