Replace the indirection through struct stack_trace with an invocation of
the storage array based interface. This results in less storage space and
indirection.

According to eMMC specification v5.1 section 6.4.3, we should issue
CMD1 repeatedly in the idle state until the eMMC is ready even if
the mmc_attach_mmc() calls this function with ocr = 0. Otherwise
some eMMC devices seems to enter the inactive mode after
mmc_init_card() issued CMD0 when the eMMC device is busy.

The frequency calculation was based on the current(max) frequency of the
CPU. However for low frequency, the value used was already the parent
frequency divided by a factor of 2.
Instead of using this frequency, this fix directly get the frequency from
the parent clock.

The sccbs for init/read/sdias/early have to be located below 2 GB, and
they are currently defined as a static buffer.
With a relocatable kernel that could reside at any place in memory, this
will no longer guarantee the location below 2 GB, so use a dynamic
GFP_DMA allocation instead.
The sclp_early_sccb buffer needs special handling, as it can be used
very early, and by both the decompressor and also the decompressed
kernel. Therefore, a fixed 4 KB buffer is introduced at 0x11000, the
former PARMAREA_END. The new PARMAREA_END is now 0x12000, and it is
renamed to HEAD_END, as it is rather the end of head.S and not the end
of the parmarea.

The device's CPU accessible memory on host is managed in a dedicated
pool, except for 2 regions - Primary Queue (PQ) and Event Queue (EQ) -
which are allocated from generic DMA pools.
Due to address length limitations of the CPU, the addresses of all these
memory regions must have the same MSBs starting at bit 40.
This patch modifies the allocation of the PQ and EQ to be also from the
dedicated pool, to ensure compliance with the limitation.

This patch changes the ASIC interface function that changes the DRAM bar
window. The change is to return the old address that the DRAM bar pointed
to instead of an error code.
This simplifies the code that use this function (mainly in debugfs) to
restore the bar to the old setting.
This is also needed for easier support in future ASICs.

We don't check for the validity of the lengths in the packet received
from the firmware. If the MPDU length received in the rx descriptor
is too short to contain the header length and the crypt length
together, we may end up trying to copy a negative number of bytes
(headlen - hdrlen < 0) which will underflow and cause us to try to
copy a huge amount of data. This causes oopses such as this one:

The "comedi_isadma" module calls `dma_alloc_coherent()` and
`dma_free_coherent()` with a NULL device pointer which is no longer
allowed. If the `hw_dev` member of the `struct comedi_device` has been
set to a valid device, that can be used instead. Unfortunately, all the
current users of the "comedi_isadma" module leave the `hw_dev` member
set to NULL. In that case, fall back to using the comedi "class" device
pointed to by the `class_dev` member if that is non-NULL. In that case,
make it "DMA-capable" with a coherent DMA mask set to the ISA bus limit
of 16MB (24 bits).

This way, slhc_free() accepts what slhc_init() returns, whether that is
an error or not.
In particular, the pattern in sl_alloc_bufs() is
slcomp = slhc_init(16, 16);
...
slhc_free(slcomp);
for the error handling path, and rather than complicate that code, just
make it ok to always free what was returned by the init function.
That's what the code used to do before commit 4ab42d78e37a ("ppp, slip:
Validate VJ compression slot parameters completely") when slhc_init()
just returned NULL for the error case, with no actual indication of the
details of the error.

When scheduling work item to read page we need to pass down the proper
bvec struct which points to the page to read into. Before this patch it
uses a randomly initialized bvec (only if PAGE_SIZE != 4096) which is
wrong.
Note that without this patch on arch/kernel where PAGE_SIZE != 4096
userspace could read random memory through a zram block device (thought
userspace probably would have no control on the address being read).

marvell_get_sset_count() returns how many statistics counters there
are. If the PHY supports fibre, there are 3, otherwise two.
marvell_get_strings() does not make this distinction, and always
returns 3 strings. This then often results in writing past the end
of the buffer for the strings.

With git commit 1e941d39493f1820475d80729a03cd7ab8c3c86d
"s390: move ipl block to .boot.preserved.data section" the earl_ipl_block
got renamed to ipl_block and became publicly available via boot_data.h.
This might cause problems with zcore, which has it's own ipl_block
variable. Thus rename the ipl_block in zcore to prevent name collision
and highlight that it's only used locally.
