commit e966eae72762ecfdbdb82627e2cda48845b9dd66 upstream.

For non-registered buffer, fastrpc driver copies the buffer and
pass it to the remote subsystem. There is a problem with current
implementation of page size calculation which is not considering
the offset in the calculation. This might lead to passing of
improper and out-of-bounds page size which could result in
memory issue. Calculate page start and page end using the offset
adjusted address instead of absolute address.

commit 6ca4ea1f88a06a04ed7b2c9c6bf9f00833b68214 upstream.

For registered  buffers, fastrpc driver sends the buffer information
to remote subsystem. There is a problem with current implementation
where the page address is being sent with an offset leading to
improper buffer address on DSP. This is leads to functional failures
as DSP expects base address in page information and extracts offset
information from remote arguments. Mask the offset and pass the base
page address to DSP.

This issue is observed is a corner case when some buffer which is registered
with fastrpc framework is passed with some offset by user and then the DSP
implementation tried to read the data. As DSP expects base address and takes
care of offsetting with remote arguments, passing an offsetted address will
result in some unexpected data read in DSP.

All generic usecases usually pass the buffer as it is hence is problem is
not usually observed. If someone tries to pass offsetted buffer and then
tries to compare data at HLOS and DSP end, then the ambiguity will be observed.

During fastrpc_rpmsg_probe, if secure device node registration
succeeds but non-secure device node registration fails, the secure
device node deregister is not called during error cleanup. Add proper
exit paths to ensure proper cleanup in case of error.

commit 235b630eda072d7e7b102ab346d6b8a2c028a772 upstream.

This commit reintroduces interrupt-based card detection previously
used in the rts5139 driver. This functionality was removed in commit
00d8521dcd23 ("staging: remove rts5139 driver code").

Reintroducing this mechanism fixes presence detection for certain card
readers, which with the current driver, will taken approximately 20
seconds to enter S3 as `mmc_rescan` has to be frozen.

[ Upstream commit 7738a7ab9d12c5371ed97114ee2132d4512e9fd5 ]

Add a quirk similar to eeprom_93xx46 to add an extra clock cycle before
reading data from the EEPROM.

The 93Cx6 family of EEPROMs output a "dummy 0 bit" between the writing
of the op-code/address from the host to the EEPROM and the reading of
the actual data from the EEPROM.

More info can be found on page 6 of the AT93C46 datasheet (linked below).
Similar notes are found in other 93xx6 datasheets.

In summary the read operation for a 93Cx6 EEPROM is:
Write to EEPROM:	110[A5-A0]	(9 bits)
Read from EEPROM:	0[D15-D0]	(17 bits)

Where:
	110 is the start bit and READ OpCode
	[A5-A0] is the address to read from
	0 is a "dummy bit" preceding the actual data
	[D15-D0] is the actual data.

Looking at the READ timing diagrams in the 93Cx6 datasheets the dummy
bit should be clocked out on the last address bit clock cycle meaning it
should be discarded naturally.

However, depending on the hardware configuration sometimes this dummy
bit is not discarded. This is the case with Exar PCI UARTs which require
an extra clock cycle between sending the address and reading the data.

commit f06e108a3dc53c0f5234d18de0bd224753db5019 upstream.

This patch disables __counted_by for clang versions &lt; 19.1.3 because
of the two issues listed below. It does this by introducing
CONFIG_CC_HAS_COUNTED_BY.

1. clang &lt; 19.1.2 has a bug that can lead to __bdos returning 0:
https://github.com/llvm/llvm-project/pull/110497

2. clang &lt; 19.1.3 has a bug that can lead to __bdos being off by 4:
https://github.com/llvm/llvm-project/pull/112636

commit f06e108a3dc53c0f5234d18de0bd224753db5019 upstream.

This patch disables __counted_by for clang versions &lt; 19.1.3 because
of the two issues listed below. It does this by introducing
CONFIG_CC_HAS_COUNTED_BY.

1. clang &lt; 19.1.2 has a bug that can lead to __bdos returning 0:
https://github.com/llvm/llvm-project/pull/110497

2. clang &lt; 19.1.3 has a bug that can lead to __bdos being off by 4:
https://github.com/llvm/llvm-project/pull/112636

so add it to fix it.

[ Upstream commit 4adf613e01bf99e1739f6ff3e162ad5b7d578d1a ]

Read buffer is allocated according to max message size, reported by
the firmware and may reach 64K in systems with pxp client.
Contiguous 64k allocation may fail under memory pressure.
Read buffer is used as in-driver message storage and not required
to be contiguous.
Use kvmalloc to allow kernel to allocate non-contiguous memory.
