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). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23370 a95241bf-73f2-0310-859d-f6bbb57e9c96

#include <image.h>
* Introduced new header directory headers/private/system which is supposed to contain headers shared by kernel and userland (mainly libroot). * Moved quite a few private kernel headers to the new location. Split several kernel headers into a shared part and one that is still kernel private. Adjusted all affected Jamfiles and source in the standard x86 build accordingly. The build for other architectures and for test code may be broken. * Quite a bit of userland code still includes private kernel headers. Mostly those are <util/*> headers. The ones that aren't strictly kernel-only should be moved to some other place (maybe headers/private/shared/util). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25486 a95241bf-73f2-0310-859d-f6bbb57e9c96

Split the commpage initialization into two parts. The second part is executed after all CPUs have been queried for their features.

void* allocate_commpage_entry(int entry, size_t size);
commpage: randomize position of commpage This patch introduces randomization of commpage position. From now on commpage table contains offsets from begining to of the commpage to the particular commpage entry. Similary addresses of symbols in ELF memory image "commpage" are just offsets from the begining of the commpage. This patch also updates KDL so that commpage entries are recognized and shown correctly in stack trace. An update of Debugger is yet to be done.
