brcmfmac: fix end of loop check (signedness bug)

The problem here is that we loop until "remained_buf_len" is less than
zero, but since it is unsigned, it never is.

"remained_buf_len" has to be large enough to hold the value from
"mgmt_ie_buf_len".  That variable is type u32, but it only holds small
values so I have changed to both variables to int.

Also I removed the bogus initialization from "mgmt_ie_buf_len" so that
GCC can detect if it is used unitialized.  I moved the declaration of
"remained_buf_len" closer to where it is used so it's easier to read.

assembly, with r4 set NULL and r5 set to kernel_init.  You can see
this in your oops dump register set - r5 is 0xc0344555, which is the
address of kernel_init plus 1 which marks the function as Thumb code.

Now, let's look at this code a little closer - this is what the
disassembly looks like:

  c000d180 <ret_from_fork>:
  c000d180:       f03a fe08       bl      c0047d94 <schedule_tail>
  c000d184:       2d00            cmp     r5, #0
  c000d186:       bf1e            ittt    ne

  c000d18a:       46fe            movne   lr, pc <-- XXXXXXX
  c000d18c:       46af            movne   pc, r5
  c000d18e:       46e9            mov     r9, sp
  c000d190:       ea4f 3959       mov.w   r9, r9, lsr #13
  c000d194:       ea4f 3949       mov.w   r9, r9, lsl #13
  c000d198:       e7c8            b.n     c000d12c <ret_to_user>
  c000d19a:       bf00            nop
  c000d19c:       f3af 8000       nop.w

This code was introduced in 9fff2fa0db911 (arm: switch to saner
kernel_execve() semantics).  I have marked one instruction, and it's
the significant one - I'll come back to that later.

Eventually, having had a successful call to kernel_execve(), kernel_init()
returns zero.

In returning, it uses the value in 'lr' which was set by the instruction
I marked above.  Unfortunately, this causes lr to contain 0xc000d18e -
an even address.  This switches the ISA to ARM on return but with a non
word aligned PC value.

So, what do we end up executing?  Well, not the instructions above - yes
the opcodes, but they don't mean the same thing in ARM mode.  In ARM mode,
it looks like this instead:

  c000d18c:       46e946af        strbtmi r4, [r9], pc, lsr #13
  c000d190:       3959ea4f        ldmdbcc r9, {r0, r1, r2, r3, r6, r9, fp, sp, lr, pc}^
  c000d194:       3949ea4f        stmdbcc r9, {r0, r1, r2, r3, r6, r9, fp, sp, lr, pc}^
  c000d198:       bf00e7c8        svclt   0x0000e7c8
  c000d19c:       8000f3af        andhi   pc, r0, pc, lsr #7
  c000d1a0:       e88db092        stm     sp, {r1, r4, r7, ip, sp, pc}
  c000d1a4:       46e81fff                        ; <UNDEFINED> instruction: 0x46e81fff
  c000d1a8:       8a00f3ef        bhi     0xc004a16c
  c000d1ac:       0a0cf08a        beq     0xc03493dc

I have included more above, because it's relevant.  The PSR flags which
we can see in the oops dump are nZCv, so Z and C are set.

All the above ARM instructions are not executed, except for two.
c000d1a0, which has no writeback, and writes below the current stack
pointer (and that data is lost when we take the next exception.) The
other instruction which is executed is c000d1ac, which takes us to...
0xc03493dc.  However, remember that bit 1 of the PC got set.  So that
makes the PC value 0xc03493de.

And that value is the value we find in the oops dump for PC.  What is
the instruction here when interpreted in ARM mode?

       0:       f71e150c                ; <UNDEFINED> instruction: 0xf71e150c

and there we have our undefined instruction (remember that the 'never'
condition code, 0xf, has been deprecated and is now always executed as
it is now being used for additional instructions.)

This path also nicely explains the state of the stack we see in the oops
dump too.

The above is a consistent and sane story for how we got to the oops
dump, which all stems from the instruction at 0xc000d18a being wrong.

the header include path sets and add uapi/ header directories") replaced
$(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the necessary

the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is
never compiled.

 (1) Remove kernel-only stuff in linux/ppp-comp.h from the UAPI.  I checked

     extra bits to unexport.

 (2) Remove linux/blk_types.h entirely from the UAPI as none of it is userspace
     applicable, and remove from the UAPI that part of linux/fs.h that was the
     reason for linux/blk_types.h being exported in the first place.  I
     discussed this with Jens Axboe before creating the patch.

 (3) The big patch of the series to disintegrate include/linux/*.h as a unit.
     This could be split up, though there would be collisions in moving stuff
     between the two Kbuild files when the parts are merged as that file is
     sorted alphabetically rather than being grouped by subsystem.

     Of this set of headers, 17 files have changed in the UAPI exported region
     since the 4th and only 8 since the 9th so there isn't much change in this
     area - as one might expect.

     It should be pretty obvious and straightforward if it does come to fixing
     up: stuff in __KERNEL__ guards stays where it is and stuff outside moves
     to the same file in the include/uapi/linux/ directory.

     If a new file appears then things get a bit more complicated as the
     "headers +=" line has to move to include/uapi/linux/Kbuild.  Only one new

  (header file inclusions, kconfig entries, array initalisers, etc) and
  someone wants to add a new item, they *always* go and stick it at the
  end of the list.

  Guys, don't do this.  Either put the new item into a randomly-chosen
  position or, probably better, alphanumerically sort the list.

lets sort all our select statements alphanumerically.  This commit was
created by the following perl:

while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {

} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
  /^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {

undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}

It found two duplicates:

Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry

and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.
