nft_cmp_fast is used for equality comparisions of size <= 4. For
comparisions of size < 4 byte a mask is calculated that is applied to
both the data from userspace (during initialization) and the register
value (during runtime). Both values are stored using (in effect) memcpy
to a memory area that is then interpreted as u32 by nft_cmp_fast.
This works fine on little endian since smaller types have the same base
address, however on big endian this is not true and the smaller types
are interpreted as a big number with trailing zero bytes.
The mask therefore must not include the lower bytes, but the higher bytes
on big endian. Add a helper function that does a cpu_to_le32 to switch
the bytes on big endian. Since we're dealing with a mask of just consequitive
bits, this works out fine.

Dan Carpenter's static code checker reports:
The patch 473ed7be0d: "gpio / ACPI: Add support for ACPI GPIO
operation regions" from Mar 14, 2014, leads to the following static
checker warning:
drivers/gpio/gpiolib-acpi.c:454 acpi_gpio_adr_space_handler()
warn: should 'gpiod_get_raw_value(desc) << i' be a 64 bit type?
This is due the fact that *value is of type u64 and gpiod_get_raw_value()
returns int. Since i can be larger than 31, it is possible that the value
returned gets wrapped.
Fix this by casting the return of gpiod_get_raw_value() to u64 first before
shift.

When we are zeroing space andit is covered by a delalloc range, we
need to punch the delalloc range out before we truncate the page
cache. Failing to do so leaves and inconsistency between the page

Similar to the write_begin problem, xfs-vm_write_end will truncate

If we fail a write beyond EOF and have to handle it in
xfs_vm_write_begin(), we truncate the inode back to the current inode
size. This doesn't take into account the fact that we may have
already made successful writes to the same page (in the case of block
size < page size) and hence we can truncate the page cache away from
blocks with valid data in them. If these blocks are delayed
allocation blocks, we now have a mismatch between the page cache and
the extent tree, and this will trigger - at minimum - a delayed
block count mismatch assert when the inode is evicted from the cache.
We can also trip over it when block mapping for direct IO - this is
the most common symptom seen from fsx and fsstress when run from
xfstests.
Fix it by only truncating away the exact range we are updating state
for in this write_begin call.

When a write fails, if we don't clear the delalloc flags from the
buffers over the failed range, they can persist beyond EOF and cause
problems. writeback will see the pages in the page cache, see they
are dirty and continually retry the write, assuming that the page
beyond EOF is just racing with a truncate. The page will eventually
be released due to some other operation (e.g. direct IO), and it
will not pass through invalidation because it is dirty. Hence it
will be released with buffer_delay set on it, and trigger warnings
in xfs_vm_releasepage() and assert fail in xfs_file_aio_write_direct
because invalidation failed and we didn't write the corect amount.
This causes failures on block size < page size filesystems in fsx
and fsstress workloads run by xfstests.
Fix it by completely trashing any state on the buffer that could be
used to imply that it contains valid data when the delalloc range
over the buffer is punched out during the failed write handling.

- add boundry and buffer overflow checks as suggested
- use kmemdup instead of kmalloc and memcpy

The correct value of .mux_offset for rk3188 seems to be 0x60
instead of 0x68.
Heiko adds:
GPIO0 only has the second two IOMUX registers:
- GRF_GPIO0C_IOMUX at 0x68
- GRF_GPIO0D_IOMUX at 0x6c
which I guess is where my mistake comes from.
It looks like there does no iomux register exist at all
for the first 16 pins.
In any case, the current number is wrong, and the 0x60
offset is the correct one, but I guess we need to
determine what the affected pins do - do they always have a
gpio mux or such?

Have the KB(),MB(),GB() macros produce unsigned longs to avoid
unintended sign extension issues with the gen2 memory size
detection.
What happens is first the uint8_t returned by
read_pci_config_byte() gets promoted to an int which gets
multiplied by another int from the MB() macro, and finally the
result gets sign extended to size_t.
Although this shouldn't be a problem in practice as all affected
gen2 platforms are 32bit AFAIK, so size_t will be 32 bits.

The code to handle any length SG lists calls edma_resume()
even before edma_start() is called. This is incorrect
because edma_resume() enables edma events on the channel
after which CPU (in edma_start) cannot clear posted
events by writing to ECR (per the EDMA user's guide).
Because of this EDMA transfers fail to start if due
to some reason there is a pending EDMA event registered
even before EDMA transfers are started. This can happen if
an EDMA event is a byproduct of device initialization.
Fix this by calling edma_resume() only if it is not the
first batch of MAX_NR_SG elements.
