kernel/x86_64: improve context switch implementation

The goal of this patch is to amortize the cost of context switch by making
the compiler aware that context switch clobbers all registers. Because all
register need to be saved anyway there is no additional cost of using
callee saved register in the function that does the context switch.


# bcb07a31 13-Jul-2012 Alex Smith <alex@alex-smith.me.uk>

Implemented the rest of the kernel debugger functions for x86_64.

Merged with the x86 implementations, mostly the same except for a
few differences. GDB stub is currently broken, will investigate
later.


# b5c9d24a 09-Jul-2012 Alex Smith <alex@alex-smith.me.uk>

Implemented threading for x86_64.

* Thread creation and switching is working fine, however threads do not yet
get interrupted because I've not implemented hardware interrupt handling
yet (I'll do that next).
* I've made some changes to struct iframe: I've removed the e/r prefixes
from the member names for both 32/64, so now they're just named ip, ax,
bp, etc. This makes it easier to write code that works with both 32/64
without having to deal with different iframe member names.


# 0897e314 02-Jul-2012 Alex Smith <alex@alex-smith.me.uk>

Merged x86_64 headers into x86 headers.

Not many changes seeing as there's not much x86_64 stuff done yet. Small
differences are handled with ifdefs, large differences (descriptors.h,
struct iframe) have separate headers under arch/x86/32 and arch/x86/64.


# 34b3b26b 10-Jan-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

Merged branch haiku/branches/developer/bonefish/optimization revision
23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
the assembly handler which now uses a jump table to call C functions
handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
rare events (signals, user debug enabling/disabling) on the
common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
common functions (currently memcpy() only). They are used in the
kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
member offsets in assembly code.

Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
(caused by refactoring and introduction of "call" debugger command).

# f94b06f9 02-Mar-2006 Axel Dörfler <axeld@pinc-software.de>

Implemented SSE2/3 support (tested with VLC).

# 35cf5155 20-Dec-2005 Axel Dörfler <axeld@pinc-software.de>

Replaced arch/thread_struct.h with arch/thread_types.h, and renamed
arch/*/thread_struct.h to arch_thread_types.h, so that it can directly
be included without having to specify the architecure.
