No need to BUG_ON() on the cache maintainance ops - they are no-ops
by default, and there is nothing in the DMA API contract that prohibits
calling them on sbus devices (even if such drivers are unlikely to
ever appear).
Similarly a dma_supported method that always returns 0 is rather
pointless. The only thing that indicates is that no one ever calls
the method on sbus devices.

Several conflicts, seemingly all over the place.
I used Stephen Rothwell's sample resolutions for many of these, if not
just to double check my own work, so definitely the credit largely
goes to him.
The NFP conflict consisted of a bug fix (moving operations
past the rhashtable operation) while chaning the initial
argument in the function call in the moved code.
The net/dsa/master.c conflict had to do with a bug fix intermixing of
making dsa_master_set_mtu() static with the fixing of the tagging
attribute location.
cls_flower had a conflict because the dup reject fix from Or
overlapped with the addition of port range classifiction.
__set_phy_supported()'s conflict was relatively easy to resolve
because Andrew fixed it in both trees, so it was just a matter
of taking the net-next copy. Or at least I think it was :-)
Joe Stringer's fix to the handling of netns id 0 in bpf_sk_lookup()
intermixed with changes on how the sdif and caller_net are calculated
in these code paths in net-next.
The remaining BPF conflicts were largely about the addition of the
__bpf_md_ptr stuff in 'net' overlapping with adjustments and additions
to the relevant data structure where the MD pointer macros are used.

fixed. The original fix, fixed time reporting of the function graph tracer
when doing a max_depth of one. This was code that can test how much the
kernel interferes with userspace. But in doing so, it could corrupt the time
keeping of the function profiler.
The issue is that the curr_ret_stack variable was being used for two
different meanings. One was to keep track of the stack pointer on the
ret_stack (shadow stack used by the function graph tracer), and the other
use case was the graph call depth. Although, the two may be closely
related, where they got updated was the issue that lead to the two different
bugs that required the two use cases to be updated differently.
The big issue with this fix is that it requires changing each architecture.
The good news is, I was able to remove a lot of code that was duplicated
within the architectures and place it into a single location. Then I could
make the fix in one place.
I pushed this code into linux-next to let it settle over a week, and before

On T4 and later sparc64 cpus we can use the fused compare and branch
instruction.
However, it can only be used if the branch destination is in the range
of a signed 10-bit immediate offset. This amounts to 1024
instructions forwards or backwards.
After the commit referenced in the Fixes: tag, the largest possible
size program seen by the JIT explodes by a significant factor.
As a result of this convergance takes many more passes since the
expanded "BPF_LDX | BPF_MSH | BPF_B" code sequence, for example,
contains several embedded branch on condition instructions.
On each pass, as suddenly new fused compare and branch instances
become valid, this makes thousands more in range for the next pass.
And so on and so forth.
This is most greatly exemplified by "BPF_MAXINSNS: exec all MSH" which
takes 35 passes to converge, and shrinks the image by about 64K.
To decrease the cost of this number of convergance passes, do the
convergance pass before we have the program image allocated, just like
other JITs (such as x86) do.

Some algorithms initialize their .cra_list prior to registration.
But this is unnecessary since crypto_register_alg() will overwrite

Apparently the useless assignment has just been copy+pasted around.
So, remove the useless assignments.
Exception: paes_s390.c uses cra_list to check whether the algorithm is

The system call tables are in different format in all
architecture and it will be difficult to manually add,
modify or delete the syscall table entries in the res-
pective 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 the implemen-
tation across all architectures.
The system call table generation script is added in
kernel/syscalls directory which contain the scripts to
generate both uapi header file and system call table
files. The syscall.tbl will be input for the scripts.
syscall.tbl contains the list of available system calls
along with system call number and corresponding entry
point. Add a new system call in this architecture will
be possible by adding new entry in the syscall.tbl file.
Adding a new table entry consisting of:
- System call number.
- ABI.
- System call name.
- Entry point name.
- Compat entry name, if required.
syscallhdr.sh and syscalltbl.sh will generate uapi header
unistd_32/64.h and syscall_table_32/64/c32.h files respect-
ively. Both .sh files will parse the content syscall.tbl
to generate the header and table files. unistd_32/64.h will
be included by uapi/asm/unistd.h and syscall_table_32/64/-
c32.h is included by kernel/syscall.S - the real system
call table.

NR_syscalls macro holds the number of system call exist
in sparc 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 syscall.tbl file contains the total number of system
calls information. So we have two option to update NR_sy-
scalls value.
1. Update NR_syscalls in asm/unistd.h manually by count-
ing the no.of system calls. No need to update NR_sys-
calls until we either add a new system call or delete
existing system call.
2. We can keep this feature it above mentioned script,
that will count the number of syscalls and keep it in
a generated file. In this case we don't need to expli-
citly update NR_syscalls in asm/unistd.h file.
The 2nd option will be the recommended one. For that, I
added the __NR_syscalls macro in uapi/asm/unistd.h along
with NR_syscalls asm/unistd.h. The macro __NR_syscalls
also added for making the name convention same across all
architecture. While __NR_syscalls isn't strictly part of
the uapi, having it as part of the generated header to
simplifies the implementation. We also need to enclose
this macro with #ifdef __KERNEL__ to avoid side effects.

returning virtual address, which is done in the following patches.

Prefer _THIS_IP_ defined in linux/kernel.h.
Most definitions of current_text_addr were the same as _THIS_IP_, but
a few archs had inline assembly instead.
This patch removes the final call site of current_text_addr, making all
of the definitions dead code.

Here is the big tty and serial pull request for 4.20-rc1
Lots of little things here, including a merge from the SPI tree in order
to keep things simpler for everyone to sync around for one platform.
Major stuff is:
- tty buffer clearing after use
- atmel_serial fixes and additions
- xilinx uart driver updates
and of course, lots of tiny fixes and additions to individual serial
drivers.
All of these have been in linux-next with no reported issues for a
while.
