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.

The intention is to return negative error codes. "pid" is already
negative but we accidentally negate it again back to positive.

Static checkers would urge us to add curly braces to this code, but
actually the code works correctly. It just isn't indented right.

When building a dynamic kernel image use relative symbols with MODVERSIONS.

Debian's gcc defaults to pie. The global Makefile already defines the -fno-pie option.
Link UML dynamic kernel image also with -no-pie to fix the build.

Explicitly export symbols so modpost doesn't complain.

Pull MIPS fixes from Ralf Baechle:
"The two indirect syscall fixes have sat in linux-next for a few days.
I did check back with a hardware designer to ensure a SYNC is really
what's required for the GIC fix and so the GIC fix didn't make it into
to linux-next in time for this final pull request.
It builds in local build tests and passes Imagination's test system"

irqchip: mips-gic: SYNC after enabling GIC region
MIPS: Remove pt_regs adjustments in indirect syscall handler
MIPS: seccomp: Fix indirect syscall args
Pull x86 fixes from Thomas Gleixner:
- Expand the space for uncompressing as the LZ4 worst case does not fit
into the currently reserved space
- Validate boot parameters more strictly to prevent out of bound access
in the decompressor/boot code
- Fix off by one errors in get_segment_base()
* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/boot: Prevent faulty bootparams.screeninfo from causing harm
x86/boot: Provide more slack space during decompression
x86/ldt: Fix off by one in get_segment_base()
A SYNC is required between enabling the GIC region and actually trying
to use it, even if the first access is a read, otherwise its possible
depending on the timing (and in my case depending on the precise
alignment of certain kernel code) to hit CM bus errors on that first
access.
Add the SYNC straight after setting the GIC base.
[paul.burton@imgtec.com:
Changes later in this series increase our likelihood of hitting this
by reducing the amount of code that runs between enabling the GIC &
accessing it.]
