expr_eliminate_dups2() in scripts/kconfig/expr.c applies two invalid
inference rules:
(FOO || BAR) && (!FOO && !BAR) -> n
(FOO && BAR) || (!FOO || !BAR) -> y
They would be correct in propositional logic, but this is a three-valued
logic, and here it is wrong in that it changes semantics. It becomes
immediately visible when assigning the value 1 to both, FOO and BAR:
(FOO || BAR) && (!FOO && !BAR)
-> min(max(1, 1), min(2-1, 2-1)) = min(1, 1) = 1
while n evaluates to 0 and
(FOO && BAR) || (!FOO || !BAR)
-> max(min(1, 1), max(2-1, 2-1)) = max(1, 1) = 1
with y evaluating to 2.
Fix it by removing expr_eliminate_dups2() and the functions that have no
use anywhere else: expr_extract_eq_and(), expr_extract_eq_or(),
and expr_extract_eq() from scripts/kconfig/expr.c
Currently the bug is not triggered in mainline, so this patch does not
modify the configuration space there. To observe the bug consider this
example:
config MODULES
def_bool y
option modules
config FOO
def_tristate m
config BAR
def_tristate m
config TEST1
def_tristate y
depends on (FOO || BAR) && (!FOO && !BAR)
if TEST1 = n
comment "TEST1 broken"
endif
config TEST2
def_tristate y
depends on (FOO && BAR) || (!FOO || !BAR)
if TEST2 = y
comment "TEST2 broken"
endif
config TEST3
def_tristate y
depends on m && !m
if TEST3 = n
comment "TEST3 broken"
endif
TEST1, TEST2 and TEST3 should all evaluate to m, but without the patch,
none of them does. It is probably not obvious that TEST3 is the same bug,
but it becomes clear when considering what happens internally to the
expression
m && !m":
First it expands to
(m && MODULES) && !(m && MODULES),
then it is transformed into
(m && MODULES) && (!m || !MODULES),
and finally due to the bug it is replaced with n.
As a side effect, this patch reduces code size in expr.c by roughly 10%
and slightly improves startup time for all configuration frontends.

On most configs task-struct is cache line aligned, which makes
the XSAVE area's 64-byte required alignment work out fine.
But on some .config's task_struct is aligned only to 16 bytes
(enforced by ARCH_MIN_TASKALIGN), which makes things like
fpu__copy() (that XSAVEOPT uses) not work so well.
I broke this in:
7366ed771f ("x86/fpu: Simplify FPU handling by embedding the fpstate in task_struct (again)")
which embedded the fpstate in the task_struct.
The alignment requirements of the FPU code were originally present
in ARCH_MIN_TASKALIGN, which still has a value of 16, which was the
alignment requirement of the FPU state area prior XSAVE. But this
link was not documented (and not required) and the link got lost
when the FPU state area was made dynamic years ago.
With XSAVEOPT the minimum alignment requirment went up to 64 bytes,
and the embedding of the FPU state area in task_struct exposed it
again - and '16' was not increased to '64'.
So fix this bug, but also try to address the underlying lost link
of information that made it easier to happen:
- document ARCH_MIN_TASKALIGN a bit better
- use alignof() to recover the current alignment requirements.
This would work in the future as well, should the alignment
requirements go up to 128 bytes with things like AVX512.
( We should probably also use the vSMP alignment rules for all
of x86, but that's for another patch. )

x86 has variable length encoding. x86 JIT compiler is trying
to pick the shortest encoding for given bpf instruction.
While doing so the jump targets are changing, so JIT is doing
multiple passes over the program. Typical program needs 3 passes.
Some very short programs converge with 2 passes. Large programs
may need 4 or 5. But specially crafted bpf programs may hit the
pass limit and if the program converges on the last iteration
the JIT compiler will be producing an image full of 'int 3' insns.

mlx4: Enable single ported VFs over IB ports
This series further enhances the support for mlx4 single ported VFs
introduced in 3.15 to work over IB ports too.
Just as quick reminder, the ConnectX3 device family exposes one PCI device
which serves both ports.
This can be non-optimal under virtualization schemes where the admin
would like the VF to expose one interface to the VM, etc.
Since all the VF interaction with the firmware passes through the PF
driver, we can emulate to the VF they have one port, and further create
a set of the VFs which act on port1 of the device and another set which
acts on port2.

As part of enabling single ported VFs over IB ports we need to handle
some of the flows for generting EQ events for VFs which don't come
into play under Eth ports.
This mainly includes port management events derived from changes of the
phyiscal port (lid change, client re-register, down/up, etc), VF pkey table
changes and VF guid changes initiated by the IB driver.
(1) make sure that events are generated only for VFs sitting on
the relevant physical port (under the ALL_SLAVES flow).
(2) before generating the event, convert from physical (one or two)
to VF port (always equals one).

When multiplexling a MAD sent from VF, we should convert the port used
by the guest to send the packet to the actual physical port which will be
used to transmit the packet, before building the relevant address-handle (AH).
This is needed under VPI for single ported VFs, since the code that builds
the AH (mlx4_ib_query_ah()) makes decisions based on the input port. If we
use the port number provided by the guest, it might have different protocol
vs. the one this packat has to go from, and hence the result could be wrong.
So far, the conversion was done after the AH was built and it worked for
single ported Eth VFs which were not enabled under VPI. When adding support
for single ported IB VFs and VPI, we hit that.

Single port VFs always provide port = 1 (even if the actual physical
port used is port 2). As such, we need to convert the port provided
by the VF to the physical port before calling into the firmware.
It turns out that the Linux mlx4 VF RoCE driver maintains a copy of
the GID table and hence this change became critical only for single
ported IB VFs, but it could be needed for other RoCE VF drivers too.

if we load the module, unload and then again try to load the module, we
will get a stackdump. In the module_exit function we are unregistering
the device and releasing the parport. So when we reach the detach
function parport is already null and the unregister_reboot_notifier()
is never called. When we again try to load the module it again tries
register_reboot_notifier() and gives us a stackdump as its earlier
registration is still not removed. It was caused by the
commit bb046fef96 ('staging: panel: register reboot')
Fix this by moving all the unregistering and releasing in the detach
function, which should be the ideal case as the detach will be called if
we try to unregister the driver or if the parport is removed.

The same area used for ioremap() is used for the MTRR area.
Convert the driver from using the x86 specific MTRR code to
the architecture agnostic arch_phys_wc_add(). arch_phys_wc_add()
will avoid MTRR if write-combining is available, in order to
take advantage of that also ensure the ioremap'd area is requested
as write-combining.
There are a few motivations for this:
a) Take advantage of PAT when available
b) Help bury MTRR code away, MTRR is architecture specific and on
x86 its replaced by PAT
c) Help with the goal of eventually using _PAGE_CACHE_UC over
_PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
de33c442e titled "x86 PAT: fix performance drop for glx,
use UC minus for ioremap(), ioremap_nocache() and
pci_mmap_page_range()")
The conversion done is expressed by the following Coccinelle
SmPL patch, it additionally required manual intervention to
address all the #ifdery and removal of redundant things which
arch_phys_wc_add() already addresses such as verbose message
about when MTRR fails and doing nothing when we didn't get

Commit 53490b545c ("staging: unisys: move periodic_work.c into the
visorbus directory") removed the Kconfig option UNISYS_VISORUTIL, but
left one reference in a Kconfig select. Remove this last reference.

Most device functions pass bus_no and dev_no around and then do a lookup
inside each function to find the dev_info struct. Instead just pass the
pointer.
This prepares us for a later conversion to using visor device.
No real technical changes. Just function header changes and little
cleanups as a result.

Convert the device attribute files to properly use visor_device.
This removes a whole bunch of checks and assumptions and simplifies
the code. Everything is straightforward.
No testing down as I can't mimic channel info correctl.
