memset on xtensa is capable of accessing user memory, but KASAN checks if memset function is actually used for that and reports it as an error: ================================================================== BUG: KASAN: user-memory-access in padzero+0x4d/0x58 Write of size 519 at addr 0049ddf9 by task init/1 Call Trace: [<b0189978>] kasan_report+0x160/0x238 [<b0188818>] check_memory_region+0xf8/0x100 [<b018891c>] memset+0x20/0x34 [<b0238b71>] padzero+0x4d/0x58 ================================================================== Use __memset in __xtensa_clear_user to avoid that.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
