[ Upstream commit 6b995f4eec34745f6cb20d66d5277611f0b3c3fa ]
In _scif_prog_signal(), the boolean variable 'x100' is used to indicate
whether the MIC Coprocessor is X100. If 'x100' is true, the status
descriptor will be used to write the value to the destination. Otherwise, a
DMA pool will be allocated for this purpose. Specifically, if the DMA pool
is allocated successfully, two memory addresses will be returned. One is
for the CPU and the other is for the device to access the DMA pool. The
former is stored to the variable 'status' and the latter is stored to the
variable 'src'. After the allocation, the address in 'src' is saved to
'status->src_dma_addr', which is actually in the DMA pool, and 'src' is
then modified.
Later on, if an error occurs, the execution flow will transfer to the label
'dma_fail', which will check 'x100' and free up the allocated DMA pool if
'x100' is false. The point here is that 'status->src_dma_addr' is used for
freeing up the DMA pool. As mentioned before, 'status->src_dma_addr' is in
the DMA pool. And thus, the device is able to modify this data. This can
potentially cause failures when freeing up the DMA pool because of the
modified device address.
This patch avoids the above issue by using the variable 'src' (with
necessary calculation) to free up the DMA pool.

The sysfs handler should return the number of bytes consumed, which in the
case of a successful write is the entire buffer. Also fix a bug where
param.data_len was being set to (count - (2 * sizeof(u32))) instead of just
(count - sizeof(u32)). The latter is correct because we skip over the
leading u32 which is our param.type, but we were also incorrectly
subtracting sizeof(u32) on the line where we were actually setting
param.data_len:
param.data_len = count - sizeof(u32);
This meant that for our example event.kernel_software_watchdog with total
length 10 bytes, param.data_len was just 2 prior to this change.
To test, successfully append an event to the log with gsmi sysfs.
This sample event is for a "Kernel Software Watchdog"

ath10k_pci_diag_write_mem may allocate big size of the dma memory
based on the parameter nbytes. Take firmware diag download as
example, the biggest size is about 500K. In some systems, the
allocation is likely to fail because it can't acquire such a large
contiguous dma memory.
The fix is to allocate a small size dma memory. In the loop,
driver copies the data to the allocated dma memory and writes to
the destination until all the data is written.

However, rather than clearing it from the correct field, remove it.
Inspection of the code shows that it can't ever have had any effect

field is never tested after it is cleared by the statement in
question.

integer:
int free;
free = __LOG_BUF_LEN - log_next_idx;
pr_info("early log buf free: %u(%u%%)\n",
free, (free * 100) / __LOG_BUF_LEN);
We support LOG_BUF_LEN of up to 1<<25 bytes. Since setup_log_buf() is
called during early init, logbuf is mostly empty, so
__LOG_BUF_LEN - log_next_idx
is close to 1<<25. Thus when we multiply it by 100, we overflow signed
integer value range: 100 is 2^6 + 2^5 + 2^2.
Example, booting with LOG_BUF_LEN 1<<25 and log_buf_len=2G

[ 0.075319] early log buf free: 33549896(-28%)

set_page_dirty says:
For pages with a mapping this should be done under the page lock
for the benefit of asynchronous memory errors who prefer a
consistent dirty state. This rule can be broken in some special
cases, but should be better not to.
Under those rules, it is only safe for us to use the plain set_page_dirty
calls for shmemfs/anonymous memory. Userptr may be used with real
mappings and so needs to use the locked version (set_page_dirty_lock).
However, following a try_to_unmap() we may want to remove the userptr and
so call put_pages(). However, try_to_unmap() acquires the page lock and
so we must avoid recursively locking the pages ourselves -- which means
that we cannot safely acquire the lock around set_page_dirty(). Since we
can't be sure of the lock, we have to risk skip dirtying the page, or
else risk calling set_page_dirty() without a lock and so risk fs
corruption.

kernel error:
virtio-ports vport2p2: Error allocating inbufs
qemu error:
virtio-serial-bus: Guest failure in adding port 2 for device \
virtio-serial0.0
This happens because buffers for the in_vq are allocated when the port is
added but are not released when the port is unplugged.
They are only released when virtconsole is removed (see a7a69ec0d8e4)
To avoid the problem and to be symmetric, we could allocate all the buffers
in init_vqs() as they are released in remove_vqs(), but it sounds like
a waste of memory.
Rather than that, this patch changes add_port() logic to ignore ENOSPC
error in fill_queue(), which means queue has already been filled.

When converting milliseconds to microseconds in commit fffa6af94894
("gpio: max77620: Use correct unit for debounce times") some ~1 ms gaps
were introduced between the various ranges supported by the controller.
Fix this by changing the start of each range to the value immediately
following the end of the previous range. This way a debounce time of,
say 8250 us will translate into 16 ms instead of returning an -EINVAL
error.
Typically the debounce delay is only ever set through device tree and
specified in milliseconds, so we can never really hit this issue because
debounce times are always a multiple of 1000 us.
The only notable exception for this is drivers/mmc/host/mmc-spi.c where
the CD GPIO is requested, which passes a 1 us debounce time. According
to a comment preceeding that code this should actually be 1 ms (i.e.
1000 us).

If the packets to sent to the guest are bigger than the buffer
available, we can split them, using multiple buffers and fixing
the length in the packet header.
This is safe since virtio-vsock supports only stream sockets.

If an SCC error occurs during a read/write command execution, a false
positive CRC error message is output.
mmcblk0: response CRC error sending r/w cmd command, card status 0x900
check_scc_error() checks SCC_RVSREQ.RVSERR bit. RVSERR detects a
correction error in the next (up or down) delay tap position. However,
since the command is successful, only retuning needs to be executed.
This has been confirmed by HW engineers.
Thus, on SCC error, set retuning flag instead of setting an error code.

In the recent commit 8b78fdb045de ("powerpc/time: Use
clockevents_register_device(), fixing an issue with large
decrementer") we changed the way we initialise the decrementer
clockevent(s).
We no longer initialise the mult & shift values of
decrementer_clockevent itself.
This has the effect of breaking PR KVM, because it uses those values
in kvmppc_emulate_dec(). The symptom is guest kernels spin forever
mid-way through boot.
For now fix it by assigning back to decrementer_clockevent the mult
and shift values.

Long/short preamble selection cannot be sampled separately, since it
depends on the BSS state. Because of that, sampling attempts to
currently not used preamble modes are not counted in the statistics,
which leads to CCK rates being sampled too often.
Fix statistics accounting for long/short preamble by increasing the
index where necessary.
Fix excessive CCK rate sampling by dropping unsupported sample attempts.
