This commit introduces the idea of a 'kpptr', which is simply an
address that is a kernel symbol. This allows for, in the future, to
have two different translations (between pointers and physical addresses)
one for kernel symbols, and one for other memory
* commit 'e74123c37b51ada05be30749edf9ad96fa6b3ab0':
x86: Remove underscores from symbols as they are in violation of the C standard
x86: Move cpus to boot_state to avoid taking address of a local variable
x86: Do not use string literals as they violate the CParser
x86: Fix compile assert
x86: Correct loop for verification
x86: Add user_data_t. Needed for verification
There is no measureable benefit from using the fastcall calling convention
and in all but one usage location the compiler should be inlining all the
functions calls, making the calling convention completely irrelevant
Note that the default is for ANSI colours to be enabled, so behaviour will be
unchanged for projects that update to this commit and make no build
configuration changes.
Guarding code with #ifdef's makes even cursor testing of 'does this code compile'
difficult due to code being hidden by the pre-processor. Using config_set in
regular C if statements is performant as the compiler can trivially detect
dead code at compile time, and at -O1 and above will not even link in symbols
referenced by dead code in these blocks, so this will not bloat image size

* commit '4413fd1be516baeac30f77da8b23c3a9fef0ec07':
x86: Make some vspace code and definitions non-static that get used by the PAE vspace code
libsel4: Define different lookup levels for PAE
* commit 'fc27f47f0cbaa72734f820160db768cbaac3a898':
x86: Move general x86 functions to common header
x86: Rename constants and functions to have X86 prefix instead of IA32 prefix
x86: Make parts of what have become 32-bit specific headers common
This definition is different to BASE_OFFSET in that it is only meant to
apply to the kernel image portion of the kernel window, and doesn't
assume that the entire window can be translated by a single offset
The reason these were not made common to begin with is so that there
was a commit that was just a rename of these files to make any merges
with other branches that might exist easier
* commit '64aed5370af89e1e1ba751941582125adfca971c':
x86: Move APIC frequency calculation to APIC init, instead of doing it before we initialize paging
