## Overview

In the Linux kernel, the following vulnerability has been resolved:

scsi: smartpqi: Use is_kdump_kernel() to check for kdump

The smartpqi driver checks the reset_devices variable to determine
whether special adjustments need to be made for kdump. This has the
effect that after a regular kexec reboot, some driver parameters such as
max_transfer_size are much lower than usual. More importantly, kexec
reboot tests have revealed memory corruption caused by the driver log
being written to system memory after a kexec.

Fix this by testing is_kdump_kernel() rather than reset_devices where
appropriate.

## Affected

- `Linux >= 058311b72f54890de824b063feb603942269b732 < 7cc670e8ebaa5241dd99c0ad75eceb8f8f64f607`
- `Linux >= 058311b72f54890de824b063feb603942269b732 < ebf673c76ce91e612a882dfaa9a3824962994aae`
- `Linux >= 058311b72f54890de824b063feb603942269b732 < a2d5a0072235a69749ceb04c1a26dc75df66a31a`
- `Linux 6.12`
