Commit 4b65a5db3627 ("arm64: Introduce uaccess_{disable,enable}
functionality based on TTBR0_EL1") added conditional user access
enable/disable. Unfortunately, a typo prevents the PAN bit from being
cleared for user access functions.
Restore the PAN functionality by adding the missing '!'.

Once upon a time it made sense to keep the mmc block device driver and its
related code, in its own directory called card. Over time, more an more
functions/structures have become shared through generic mmc header files,
between the core and the card directory. In other words, the relationship
between them has become closer.
By sharing functions/structures via generic header files, it becomes easy
for outside users to abuse them. In a way to avoid that from happen, let's
move the files from card directory into the core directory, as it enables
us to move definitions of functions/structures into mmc core specific
header files.
Note, this is only the first step in providing a cleaner mmc interface for
outside users. Following changes will do the actual cleanup, as that is not
part of this change.

/proc/xen/xenbus does not work correctly. A read blocked waiting for
a xenstore message holds the mutex needed for atomic file position
updates. This blocks any writes on the same file handle, which can
deadlock if the write is needed to unblock the read.

During page fault handling we check the last instruction to understand
if the fault was for a read or for a write. By default we fall back to
read. New instructions were added to the openrisc 1.1 spec for an
atomic load/store pair (l.lwa/l.swa).
This patch adds the opcode for l.swa (0x33) allowing it to be treated as
a write operation.

The of_platform_populate call in the openrisc arch code is now redundant
as the DT core provides a default call. Openrisc has a NULL match table
which means only top level nodes with compatible strings will have
devices creates. The default version will also descend nodes in the
match table such as "simple-bus" which should be fine as openrisc
doesn't have any of these (though it is preferred that memory-mapped
peripherals be grouped under a bus node(s)).

Fix signal handling for when signals are handled as the result of timers
or exceptions, previous code assumed syscalls. This was noticeable with X
crashing where it uses SIGALRM.
This patch restores all regs before returning to userspace via
_resume_userspace instead of via syscall return path.
The rt_sigreturn syscall is more like a context switch than a function
call; it entails a return from one context (the signal handler) to another
(the process in question). For a context switch like this there are
effectively no call-saved regs that remain constant across the transition.

On OpenRISC, with its 8k pages, PAGE_SHIFT is defined to be 13.
That makes the expression (1UL << (PAGE_SHIFT-2)) evaluate
to 2048.
The correct value for PTRS_PER_PGD should be 256.
Correcting the PTRS_PER_PGD define unveiled a bug in map_ram(),
where PTRS_PER_PGD was used when the intent was to iterate
over a set of page table entries.
This patch corrects that issue as well.

Provide an s390 specific memmove implementation which is faster than
the generic implementation which copies byte-wise.
For non-destructive (as defined by the mvc instruction) memmove
operations the following table compares the old default implementation
versus the new s390 specific implementation:
size old new
1 1ns 8ns
2 2ns 8ns
4 4ns 8ns
8 7ns 8ns
16 17ns 8ns
32 35ns 8ns
64 65ns 9ns
128 146ns 10ns
256 298ns 11ns
512 537ns 11ns
1024 1193ns 19ns
2048 2405ns 36ns
So only for very small sizes the old implementation is faster. For
overlapping memmoves, where the mvc instruction can't be used, the new
implementation is as slow as the old one.

The early C code within arch/s390/kernel/early.c saves ipl parameters
before the bss section is cleared. When doing that it jumps to code
that is potentially gcov/kcov instrumented. That code in turn will
corrupt an initrd that potentially may reside in the not yet ready to
be used bss section.
Instead of excluding more and more code from gcov/kcov instrumentation
provide an early memmove function which will be used to save ipl
parameters. The verification if these parameters are actually valid
will be done later.

Early C code must be excluded from gcov profiling since it may write
to the bss section before
- a potential initrd that resides there is rescued
- the bss section is initialized (zeroed)
This patch only addresses the problem that early code is instrumented
for profiling, but not the problem that it jumps into other code that
is still instrumented. That problem will be fixed with a follow-on
patch.

With this feature, the DASD device driver more robustly handles DASDs
that are attached via multiple channel paths and are subject to
constant Interface-Control-Checks (IFCCs) and Channel-Control-Checks
(CCCs) or loss of High-Performance-FICON (HPF) functionality on one or
more of these paths.
If a channel path does not work correctly, it is removed from normal
operation as long as other channel paths are available. All extended
error recovery states can be queried and reset via user space
interfaces.

The HID report buffers that are initially allocated on i2c_hid_probe()
might not be big enough to hold the HID reports from a specific device,
in which case they will be freed and new ones will be allocated in
i2c_hid_start(), at point which the device's report size is known. But
at this point ihid->irq is already running, and may call
i2c_hid_get_input() which passes ihid->inbuf to i2c_master_recv(). Since
this handler runs in a separate thread, ihid->inbuf may be freed at this
very moment, and i2c_master_recv() will write on memory which may be
already owned by a different part of the kernel, corrupting its data.
This problem has been observed on an Asus UX360UA laptop which has an
I2C touchpad, and results in a complete system freeze or an unusable
slowness with a lof of "BUG: unable to handle kernel paging request at
<address>" warnings. Enabling SLUB debugging shows a use-after-free
warning on memory allocated in i2c_hid_alloc_buffers() and freed in
i2c_hid_free_buffers():
