* Fix some broken code
* Add some ASSERTs
* Use ApicWriteIORedirectionEntry where appropriate
* Use KeQueryInterruptHandler/KeRegisterInterruptHandler to save/restore the old handler instead of saving the KIDTENTRY
* Move HalpProfileInterruptHandler to apictimer.c and implement it
* Use READ/WRITE_REGISTER macros
* Add some symbolic names
Lazy IRQL feature has issues with interrupt delivery on VirtualBox, so disable it for now.
For the feature description, see commit d28eae967a
Meanwhile, merge and clean up APIC headers a bit
- Rename UP -> PIC. The "up" folder in fact contains the code for
managing the Intel 8259 PIC chip
- Move amd64/processor.c -> apic/processor.c. The code is not tied to
amd64
- Remove platform from "halinit*" files. They already reside in the
corresponding folder
- Change INIT_FUNCTION and INIT_SECTION to CODE_SEG("INIT") and DATA_SEG("INIT") respectively
- Remove INIT_FUNCTION from function prototypes
- Remove alloc_text pragma calls as they are not needed anymore
* Add an NDK header to define INIT_FUNCTION/INIT_SECTION globally
* Use _declspec(allocate(x)) and _declspec(code_seg(x)) on MSVC versions that support it
* Use INIT_FUNCTION on functions only and INIT_SECTION on data only (required by MSVC)
* Place INIT_FUNCTION before the return type (required by MSVC)
* Make sure declarations and implementations share the same modifiers (required by MSVC)
* Add a global linker option to suppress warnings about defined but unused INIT section
* Merge INIT section into .text in freeldr
