docs: move x86 documentation into Documentation/arch/

2023-03-30T18:58:51+00:00

Move the x86 documentation under Documentation/arch/ as a way of cleaning up the top-level directory and making the structure of our docs more closely match the structure of the source directories it describes. All in-kernel references to the old paths have been updated.

Documentation: x86: Fix obsolete name of page fault handler

2022-04-05T16:28:36+00:00

Since commit 91eeafea1e4b ("x86/entry: Switch page fault exception to IDTENTRY_RAW"), the function name of the page fault handler is out of date. And because of commit aa37c51b9421 ("x86/mm: Break out user address space handling"), the description of search_exception_table is not correct anymore. It may mislead the user who wants to use the documentation to figure out the page fault handler. Also, fix typo and add the parentheses after function and macro name.

Documentation: x86: exception-tables: document CONFIG_BUILDTIME_TABLE_SORT

2020-03-27T16:50:01+00:00

Provide more information about __ex_table sorting post link. The exception tables and fixup tables use a commonly recurring pattern in the kernel of storing the address of labels as date in custom ELF sections, then finding these sections, iterating elements within them, and possibly revisiting them or modifying the data at these addresses. Sorting readonly arrays to minimize runtime penalties is quite clever. Suggested-by: H.
