Xiaolong Ye reported the following failure on Broadwell D server:

  EDAC sbridge: Some needed devices are missing
  EDAC MC: Removed device 0 for sbridge_edac.c Broadwell SrcID#0_Ha#0: DEV 0000:ff:12.0
  EDAC sbridge: Couldn't find mci handler
  EDAC sbridge: Failed to register device with error -19.

Broadwell D (only IMC0 per socket) and Broadwell X (IMC0 and IMC1 per
socket) use the same PCI device IDs for IMC0 per socket, then they
share pci_dev_descr_broadwell_table (n_imcs_per_sock=2). In this case,
Broadwell D wrongly creates the nonexistent SOCK EDAC memory controller
and reports above error messages, since it has no IMC1 per socket.

Avoid creating the nonexistent SOCK memory controller.

EDAC assigns logical memory controller numbers in the order that we find
memory controllers, which depends on which PCI bus they are on. Some
systems end up with MC0 on socket0, others (e.g Haswell) have MC0 on
socket3.

All this is made more confusing for users because we use the string
"Socket" while generating names for memory controllers, but the number
that we attach there is the memory controller number. E.g.

  EDAC MC0: Giving out device to module sbridge_edac.c controller
    Haswell Socket#0: DEV 0000:ff:12.0 (INTERRUPT)

Change the names to say "SrcID#%d" (where the number we use is read from
the h/w associated with the memory controller instead of some logical
number internal to the EDAC driver). New message:

  EDAC MC0: Giving out device to module sbridge_edac.c controller

The code to fetch a 64-bit value from user space was entirely buggered,
and has been since the code was merged in early 2016 in commit
b2f68038 ("x86/mm/32: Add support for 64-bit __get_user() on 32-bit
kernels").

Happily the buggered routine is almost certainly entirely unused, since
the normal way to access user space memory is just with the non-inlined
"get_user()", and the inlined version didn't even historically exist.

The normal "get_user()" case is handled by external hand-written asm in
arch/x86/lib/getuser.S that doesn't have either of these issues.

There were two independent bugs in __get_user_asm_u64():

 - it still did the STAC/CLAC user space access marking, even though
   that is now done by the wrapper macros, see commit 11f1a4b9
   ("x86: reorganize SMAP handling in user space accesses").

   This didn't result in a semantic error, it just means that the
   inlined optimized version was hugely less efficient than the
   allegedly slower standard version, since the CLAC/STAC overhead is
   quite high on modern Intel CPU's.

 - the double register %eax/%edx was marked as an output, but the %eax
   part of it was touched early in the asm, and could thus clobber other
   inputs to the asm that gcc didn't expect it to touch.

   In particular, that meant that the generated code could look like
   this:

        mov    (%eax),%eax
        mov    0x4(%eax),%edx

   where the load of %edx obviously was _supposed_ to be from the 32-bit
   word that followed the source of %eax, but because %eax was
   overwritten by the first instruction, the source of %edx was
   basically random garbage.

The fixes are trivial: remove the extraneous STAC/CLAC entries, and mark
the 64-bit output as early-clobber to let gcc know that no inputs should
alias with the output register.

Al noticed that unsafe_put_user() had type problems, and fixed them in
commit a7cc722f ("fix unsafe_put_user()"), which made me look more
at those functions.

It turns out that unsafe_get_user() had a type issue too: it limited the
largest size of the type it could handle to "unsigned long".  Which is
fine with the current users, but doesn't match our existing normal
get_user() semantics, which can also handle "u64" even when that does
not fit in a long.

While at it, also clean up the type cast in unsafe_put_user().  We
actually want to just make it an assignment to the expected type of the
pointer, because we actually do want warnings from types that don't
convert silently.  And it makes the code more readable by not having
that one very long and complex line.

[ This patch might become stable material if we ever end up back-porting
  any new users of the unsafe uaccess code, but as things stand now this
  doesn't matter for any current existing uses. ]
