The variable debug_buffer is a global variable which is allocated
and free'd when open/close is called on debugfs file -
"/sys/kernel/debug/rmt_storage/info". The current code doesn't
have locks to handle concurrent accesses to the above file.
This results into use after free issue when debug_buffer is
accessed by two threads at the same time. Fix this by adding
a mutex lock to protect this global variable.

Bug: 33845464
commit 4d31a2588ae37a5d0f61f4d956454e9504846aeb upstream.
The variable i contains a total number of resources (including
IORESOURCE_IRQ). However, we want the dmem_region_start to point
after the last resource of type IORESOURCE_MEM. The original behaviour
leads (very likely) to skipping several UIO mapping regions and makes
them useless. Fix this by computing dmem_region_start from the uiomem
which points to the last used UIO mapping.

Uio's default mmap for physical memory uses
pgprot_noncached which is strongly ordered.
Using pgprot_writecombine would allow for
unalligned access.
Add a custom mmap function when registering uio
to allow unalligned access to the mmaped
region.

Add an addtional line to the debugfs info printed to indicate

The shared memory regions used for the UIO devices use physical
addresses that are hardcoded in the device tree which creates a
dependency on the memory map.
Add support to dynamically allocate uncached physically contiguous
memory for the shared buffer at device probe and allow clients (remote-
fs and rfsa) to request this shared buffer address through Kernel QMI
and remove this dependency.

The following commits have been reverted from this merge, as they are
known to introduce new bugs and are currently incompatible with our
audio implementation. Investigation of these commits is ongoing, and
they are expected to be brought in at a later time:
86e6de7 ALSA: compress: fix drain calls blocking other compress functions (v6)
16442d4 ALSA: compress: fix drain calls blocking other compress functions
This merge commit also includes a change in block, necessary for
compilation. Upstream has modified elevator_init_fn to prevent race
conditions, requring updates to row_init_queue and test_init_queue.

Add new device driver to provide a standard interface for its
clients (like RemoteFS and RFSA) to be able to memory map their
respective allotted shared memory address in the client's address space.
The shared memory (a transport buffer) address is unique for each
individual client and is made available to the driver via device tree.
This driver uses the existing UIO framework to facilitate the clients
mmap requirements. Each individual client will be able to use a unique
UIO device for this purpose.

Highbank has grown support for Calxeda's next generation of hardware,
ECX-2000.
clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also

The uio device should not fail on open just because one memory allocation
fails. The device might export several regions, the failure of some of
which may or may not be a problem for the user space driver. Failing
regions will remain unmapped, and successful regions will be mapped and
exported to user space. Also deals with the case where failing to map
a region after successfully allocating others would not unmap the
successfully allocated regions before dying.

This device extends the uio_pdrv_genirq driver to provide limited
dynamic memory allocation for UIO devices. This allows UIO devices
to use CMA and IOMMU allocated memory regions. This driver is based
on the uio_pdrv_genirq driver and provides the same generic interrupt
handling capabilities. Like uio_prdv_genirq,
a fixed number of memory regions, defined in the platform device's
.resources field are exported to userpace. This driver adds the ability
to export additional regions whose number and size are known at boot time,
but whose memory is not allocated until the uio device file is opened for
the first time. When the device file is closed, the allocated memory block
is freed. Physical (DMA) addresses for the dynamic regions are provided to
the userspace via /sys/class/uio/uioX/maps/mapY/addr in the same way as
static addresses are when the uio device file is open, when no processes
are holding the device file open, the address returned to userspace is
DMA_ERROR_CODE.

A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA,
currently it lost original meaning but still has some effects:
| effect | alternative flags
-+------------------------+---------------------------------------------
1| account as reserved_vm | VM_IO
2| skip in core dump | VM_IO, VM_DONTDUMP
3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
This patch removes reserved_vm counter from mm_struct. Seems like nobody
cares about it, it does not exported into userspace directly, it only
reduces total_vm showed in proc.
Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP.
remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP.
remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

pci_block_user_cfg_access was designed for the use case that a single
context, the IPR driver, temporarily delays user space accesses to the
config space via sysfs. This assumption became invalid by the time
pci_dev_reset was added as locking instance. Today, if you run two loops
in parallel that reset the same device via sysfs, you end up with a
kernel BUG as pci_block_user_cfg_access detect the broken assumption.
This reworks the pci_block_user_cfg_access to a sleeping service
pci_cfg_access_lock and an atomic-compatible variant called
pci_cfg_access_trylock. The former not only blocks user space access as
before but also waits if access was already locked. The latter service
just returns false in this case, allowing the caller to resolve the
conflict instead of raising a BUG.
Adaptions of the ipr driver were originally written by Brian King.

To support >32-bit physical addresses for UIO_MEM_PHYS type we need to
extend the width of 'addr' in struct uio_mem. Numerous platforms like
embedded PPC, ARM, and X86 have support for systems with larger physical
address than logical.
Since 'addr' may contain a physical, logical, or virtual address the
easiest solution is to just change the type to 'phys_addr_t' which
should always be greater than or equal to the sizeof(void *) such that
it can properly hold any of the address types.
For physical address we can support up to a 44-bit physical address on a
typical 32-bit system as we utilize remap_pfn_range() for the mapping of
the memory region and pfn's are represnted by shifting the address by
the page size (typically 4k).

Remove the __devinitconst to fix the section mismatch.
WARNING: drivers/uio/built-in.o(.data+0x2e8): Section mismatch in
reference from the variable uio_pdrv_genirq to the variable
.devinit.rodata:uio_of_genirq_match
The variable uio_pdrv_genirq references
the variable __devinitconst uio_of_genirq_match
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the
variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one,
*_console

The spin_lock in uio_pci_generic.c is only used in the interrupt
handler, which cannot be executed twice at the same time.
That makes the lock rather pointless. This patch removes it.

Adding OF binding to genirq.
Version string is setup to the "devicetree".
Compatible string is not setup for now but you can add your
custom compatible string to uio_of_genirq_match structure.
For example with "vendor,device" compatible string:
static const struct of_device_id __devinitconst uio_of_genirq_match[] = {
{ .compatible = "vendor,device", },
{ /* empty for now */ },
};

Several fixes as well where the +1 was missing.
Done via coccinelle scripts like:
@@
struct resource *ptr;
@@
- ptr->end - ptr->start + 1
+ resource_size(ptr)
and some grep and typing.
Mostly uncompiled, no cross-compilers.

This patch implements PRUSS (Programmable Real-time Unit Sub System)
UIO driver which exports SOC resources associated with PRUSS like
I/O, memories and IRQs to user space. PRUSS is dual 32-bit RISC
processors which is efficient in performing embedded tasks that
require manipulation of packed memory mapped data structures and
handling system events that have tight real time constraints. This
driver is currently supported on Texas Instruments DA850, AM18xx and
OMAP-L138 devices.
For example, PRUSS runs firmware for real-time critical industrial
communication data link layer and communicates with application stack
running in user space via shared memory and IRQs.
