  == Kernel header files ==
  
- This release of Fedora has been built using Linux kernel headers exported directly from the kernel, using the new {{{headers_install}}} feature of the 2.6.18 kernel. Thus, the {{{glibc-kernheaders}}} package has been removed and replaced with a subpackage of the kernel; {{{kernel-headers}}}.
+ This release of Fedora has been built using Linux kernel headers exported directly from the kernel, using the new `headers_install` feature of the 2.6.18 kernel. Thus, the `glibc-kernheaders` package has been removed and replaced with `kernel-headers`, a subpackage of `kernel`.
  
- Developers may notice some changes between these new kernel headers and what was present before, including but not limited to:
+ Developers may notice some changes between these new kernel headers and what was present before, including but not limited to the following:
  
-  * The {{{<linux/compiler.h>}}} header file has been removed, since it contains nothing of use to userspace.
+  * The `<linux/compiler.h>` header file has been removed, since it contains nothing of use to userspace.
  
-  * The {{{_syscallX()}}} macros are removed. Userspace should use {{{syscall()}}} from the C library instead.
+  * The `_syscallX()` macros are removed. Userspace should use `syscall()` from the C library instead.
  
-  * The {{{PAGE_SIZE}}} macro is removed from some architectures, since the page size is variable. Userspace should be using {{{sysconf(_SC_PAGE_SIZE)}}} or {{{getpagesize()}}} instead.
+  * The `PAGE_SIZE` macro is removed from some architectures, since the page size is variable. Userspace should be using `sysconf(_SC_PAGE_SIZE)` or `getpagesize()` instead.
  
-  * The {{{<asm/atomic.h>}}} and {{{<asm/bitops.h>}}} header files have been removed. These were not designed for use in userspace, and would fail to compile on some architectures while silently giving non-atomic behaviour on others. The C compiler provides its own [http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/Atomic-Builtins.html#Atomic-Builtins atomic builtin functions] which are suitable for use in userspace programs instead.

-  * Content which was previously protected with {{{#ifdef __KERNEL__}}} is now elided completely with the {{{unifdef}}} tool, so defining {{{__KERNEL___}}} in order to see parts which should not be visible to userspace is no longer effective.

  In addition, some other header files which are not suitable for use in userspace have been removed, and still more headers have been edited to remove unsuitable content.
