2fca11bb46 docs/zh_CN: add back the missing part in the English version 
The zh_CN kasan document misses the code change in commit eefe68280c
("kasan: Add documentation for CONFIG_KASAN_EXTRA_INFO").

Fix this by adding the translation of the missing part.

d831091484 kasan: docs: update descriptions about test file and module 
After commit f7e01ab828 ("kasan: move tests to mm/kasan/"), the test
file is renamed to mm/kasan/kasan_test.c and the test module is renamed to
kasan_test.ko, so update the descriptions in the document.

While at it, update the line number and testcase number when the tests
kmalloc_large_oob_right and kmalloc_double_kzfree failed to sync with the
current code in mm/kasan/kasan_test.c.

5aa4ac64e6 LoongArch: Add KASAN (Kernel Address Sanitizer) support 
1/8 of kernel addresses reserved for shadow memory. But for LoongArch,
There are a lot of holes between different segments and valid address
space (256T available) is insufficient to map all these segments to kasan
shadow memory with the common formula provided by kasan core, saying
(addr >> KASAN_SHADOW_SCALE_SHIFT) + KASAN_SHADOW_OFFSET

So LoongArch has a arch-specific mapping formula, different segments are
mapped individually, and only limited space lengths of these specific
segments are mapped to shadow.

At early boot stage the whole shadow region populated with just one
physical page (kasan_early_shadow_page). Later, this page is reused as
readonly zero shadow for some memory that kasan currently don't track.
After mapping the physical memory, pages for shadow memory are allocated
and mapped.

Functions like memset()/memcpy()/memmove() do a lot of memory accesses.
If bad pointer passed to one of these function it is important to be
caught. Compiler's instrumentation cannot do this since these functions
are written in assembly.

KASan replaces memory functions with manually instrumented variants.
Original functions declared as weak symbols so strong definitions in
mm/kasan/kasan.c could replace them. Original functions have aliases
with '__' prefix in names, so we could call non-instrumented variant
if needed.
