When Block Device Layer is disabled, BLK_MAX_SEGMENT_SIZE is undefined.
The rtrs is a transport library and should compile independently of the
block layer. The desired max segment size should be passed down by the
user.
Introduce max_segment_size parameter for the rtrs_clt_open() call.

The problem is that "req->sg_cnt" is an unsigned int so if "nr" is
negative, it gets type promoted to a high positive value and the condition
is false. This patch fixes it by handling negatives separately.

Introduce public header which provides set of API functions to establish
RDMA connections from client to server machine using RTRS protocol, which
manages RDMA connections for each session, does multipathing and load
balancing.
Main functions for client (active) side:
rtrs_clt_open() - Creates set of RDMA connections incapsulated
in IBTRS session and returns pointer on RTRS
session object.
rtrs_clt_close() - Closes RDMA connections associated with RTRS
session.
rtrs_clt_request() - Requests zero-copy RDMA transfer to/from
server.
Main functions for server (passive) side:
rtrs_srv_open() - Starts listening for RTRS clients on specified
port and invokes RTRS callbacks for incoming
RDMA requests or link events.
rtrs_srv_close() - Closes RTRS server context.

I goofed when I added mm->user_ns support to would_dump. I missed the
fact that in the case of binfmt_loader, binfmt_em86, binfmt_misc, and
binfmt_script bprm->file is reassigned. Which made the move of
would_dump from setup_new_exec to __do_execve_file before exec_binprm
incorrect as it can result in would_dump running on the script instead
of the interpreter of the script.
The net result is that the code stopped making unreadable interpreters
undumpable. Which allows them to be ptraced and written to disk
without special permissions. Oops.
The move was necessary because the call in set_new_exec was after
bprm->mm was no longer valid.
To correct this mistake move the misplaced would_dump from
__do_execve_file into flos_old_exec, before exec_mmap is called.
I tested and confirmed that without this fix I can attach with gdb to
a script with an unreadable interpreter, and with this fix I can not.

Pull powerpc fixes from Michael Ellerman:
- A fix for unrecoverable SLB faults in the interrupt exit path,
introduced by the recent rewrite of interrupt exit in C.
- Four fixes for our KUAP (Kernel Userspace Access Prevention) support
on 64-bit. These are all fairly minor with the exception of the
change to evaluate the get/put_user() arguments before we enable user
access, which reduces the amount of code we run with user access
enabled.
- A fix for our secure boot IMA rules, if enforcement of module
signatures is enabled at runtime rather than build time.
- A fix to our 32-bit VDSO clock_getres() which wasn't falling back to
the syscall for unknown clocks.
- A build fix for CONFIG_PPC_KUAP_DEBUG on 32-bit BookS, and another
for 40x.
Thanks to: Christophe Leroy, Hugh Dickins, Nicholas Piggin, Aurelien
Jarno, Mimi Zohar, Nayna Jain.
