+Boot parameters
+~~~~~~~~~~~~~~~
+
+KASAN is affected by the generic ``panic_on_warn`` command line parameter.
+When it is enabled, KASAN panics the kernel after printing a bug report.
+
+By default, KASAN prints a bug report only for the first invalid memory access.
+With ``kasan_multi_shot``, KASAN prints a report on every invalid access. This
+effectively disables ``panic_on_warn`` for KASAN reports.
+
+Alternatively, independent of ``panic_on_warn``, the ``kasan.fault=`` boot
+parameter can be used to control panic and reporting behaviour:
+
+- ``kasan.fault=report`` or ``=panic`` controls whether to only print a KASAN
+  report or also panic the kernel (default: ``report``). The panic happens even
+  if ``kasan_multi_shot`` is enabled.
+
+Hardware Tag-Based KASAN mode (see the section about various modes below) is
+intended for use in production as a security mitigation. Therefore, it supports
+additional boot parameters that allow disabling KASAN or controlling features:
+
+- ``kasan=off`` or ``=on`` controls whether KASAN is enabled (default: ``on``).
+
+- ``kasan.mode=sync``, ``=async`` or ``=asymm`` controls whether KASAN
+  is configured in synchronous, asynchronous or asymmetric mode of
+  execution (default: ``sync``).
+  Synchronous mode: a bad access is detected immediately when a tag
+  check fault occurs.
+  Asynchronous mode: a bad access detection is delayed. When a tag check
+  fault occurs, the information is stored in hardware (in the TFSR_EL1
+  register for arm64). The kernel periodically checks the hardware and
+  only reports tag faults during these checks.
+  Asymmetric mode: a bad access is detected synchronously on reads and
+  asynchronously on writes.
+
+- ``kasan.vmalloc=off`` or ``=on`` disables or enables tagging of vmalloc
+  allocations (default: ``on``).
