This driver depends on the CONFIG_DMV182 symbol which is not defined anywhere,
and this means that this driver is dead.

In case the driver is not probed - due to config mismatches or errors
in the DTS files - dev_get_drvdata() returns NULL, leading to an Ooops
during boot.
Make elm_config() return an error in such cases to propagate the error
up to the user, so it can fall back to software mode.

This device was reported over a year ago on OpenWrt mailing list in the
thread [OpenWrt-Devel] RedBoot partition table with winbond m25q128vb
(unfortunately, I can't find message id). Macpaul seemed to have
problems with partition driver, but it seems the device was working OK.

Not all SST devices implement the SST byte programming command.
Some devices (like SST25VF064C) implement only standard m25p80 page
write command.
Now SPI flash devices that need sst_write() are explicitly marked
with new SST_WRITE flag and the decision to use sst_write() is based
on this flag instead of manufacturer id.

Previously, partitions were limited to less than 4 GiB in size because

Up until now we identified NAND chips by the 'device ID' part of the full chip
ID array, which is the second full ID array byte. However, the newest flashes
use the same device ID for chips with identical page and eraseblock sizes, but
different OOB sizes. And unfortunately, it is not clear if there is a
"standard" way to fetch the OOB size from chip's full ID array. Here is an
example:
Toshiba TC58NVG2S0F: 0x98, 0xdc, 0x90, 0x26, 0x76, 0x15, 0x01, 0x08
Toshiba TC58NVG3S0F: 0x98, 0xd3, 0x90, 0x26, 0x76, 0x15, 0x02, 0x08
The first one is a 512MiB NAND chip with 4KiB NAND pages, 256KiB eraseblock
size and 224 bytes OOB. The second one is a 1GiB NAND chip with the same page
and eraseblock sizes, but with 232 bytes OOB.
This means that we have to store full ID in our NAND flashes table in order to
distinguish between these 2.
This patch adds the 'id[8]' field to the 'struct nand_flash_dev' structure, and
it makes it to be a part of anonymous union, where the second member is a
structure containing the 'mfr_id' and 'dev_id' bytes. The union makes sure that
'mfr_id' refers the same RAM address as 'id[0]' and 'dev_id' refers the same
RAM address as 'id[1]'. The only motivation for the union is an assumption that
'type->dev_id' is more readable than 'type->id[1]'.

Introduce helper macros for defining NAND chips. These macros do not really add
much value in the current code-base. However, we are going to add full ID
support which adds some more complexity to the table, and helper macros become

The 'id' is a bit confusing name because NAND IDs are multi-byte. Re-name
it to 'dev_id' to make it clear that this is the "device ID" part (the second
byte).

We have only one AG-AND driver and it was not touched since 2005. It looks
like AG-AND was not really make it to mass-production and can be considered
a dead technology.
Along with the AG-AND support, this patch removes the BBT_AUTO_REFRESH feature,
because the only user of this feature is AG-AND. And even though it is
implemented as a generic feature, I prefer to remove it because NAND flashes do
not really need it in this form.

The MTD subsystem has its own small museum of ancient NANDs in a form of the
CONFIG_MTD_NAND_MUSEUM_IDS configuration option. The museum contains stone age
NANDs with 256 bytes pages, as well as iron age NANDs with 512 bytes per page
and up to 8MiB page size.
It is with great sorrow that I inform you that the museum is being
decommissioned. The MTD subsystem is out of budget for Kconfig options and
already has too many of them, and there is a general kernel trend to simplify
the configuration menu.
We remove the stone age exhibits along with closing the museum, but some of the
iron age ones are transferred to the regular NAND depot. Namely, only those
which have unique device IDs are transferred, and the ones which have
conflicting device IDs are removed.

Commit 1d9d8639c063 ("perf,x86: fix kernel crash with PEBS/BTS after
suspend/resume") fixed a crash when doing PEBS performance profiling
after resuming, but in using init_debug_store_on_cpu() to restore the
DS_AREA mtrr it also resulted in a new WARN_ON() triggering.
init_debug_store_on_cpu() uses "wrmsr_on_cpu()", which in turn uses CPU
cross-calls to do the MSR update. Which is not really valid at the
early resume stage, and the warning is quite reasonable. Now, it all
happens to _work_, for the simple reason that smp_call_function_single()
ends up just doing the call directly on the CPU when the CPU number
matches, but we really should just do the wrmsr() directly instead.
This duplicates the wrmsr() logic, but hopefully we can just remove the
wrmsr_on_cpu() version eventually.

This patch change the kernel VSID range so that we limit VSID_BITS to 37.
This enables us to support 64TB with 65 bit VA (37+28). Without this patch
we have boot hangs on platforms that only support 65 bit VA.
With this patch we now have proto vsid generated as below:
We first generate a 37-bit "proto-VSID". Proto-VSIDs are generated
from mmu context id and effective segment id of the address.
For user processes max context id is limited to ((1ul << 19) - 5)
for kernel space, we use the top 4 context ids to map address as below
0x7fffc - [ 0xc000000000000000 - 0xc0003fffffffffff ]
0x7fffd - [ 0xd000000000000000 - 0xd0003fffffffffff ]

Users report that an extent map's list is still linked when it's actually
going to be freed from cache.
The story is that
a) when we're going to drop an extent map and may split this large one into
smaller ems, and if this large one is flagged as EXTENT_FLAG_LOGGING which means
that it's on the list to be logged, then the smaller ems split from it will also
be flagged as EXTENT_FLAG_LOGGING, and this is _not_ expected.
b) we'll keep ems from unlinking the list and freeing when they are flagged with
EXTENT_FLAG_LOGGING, because the log code holds one reference.
The end result is the warning, but the truth is that we set the flag
EXTENT_FLAG_LOGGING only during fsync.
So clear flag EXTENT_FLAG_LOGGING for extent maps split from a large one.

The patch here moves two defines from asm-generic/atomic.h to
asm-generic/cmpxchg.h to make things work as they should.
- The VIRT_TO_BUS selector was added for OpenRISC, but OpenRISC does
not have the virt_to_bus methods, so there's a patch to remove it
again.
