* 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

* Added the possibility to debug latency issues with spinlocks. * When DEBUG_SPINLOCK_LATENCIES is 1, the system will panic if any spinlock is held longer than DEBUG_LATENCY micro seconds (currently 200). If your system doesn't boot anymore, a new safemode setting can disable the panic. * Besides some problems during boot when the MTRRs are set up, 200 usecs work fine here if all debug output is turned off (the output stuff is definitely problematic, though I don't have a good idea on how to improve upon it a lot). * Renamed the formerly BeOS compatible safemode settings to look better; there is no need to be compatible there. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33953 a95241bf-73f2-0310-859d-f6bbb57e9c96

Initial work towards supporting IO APICs. This cannot work for PCI interrupts though until we use ACPI for proper PCI IRQ routing through the IO APIC. Therefore the IO APIC code path is not yet enabled and the IO APIC isn't used. ISA interrupts would work though, as would PCI interrupts if you'd hardcode them for your specific configuration. Note that this change also modifies some parts in the bootloader and in the PIC setup to make local APICs available even on non-SMP systems. This causes APIC timers to be used instead the normal PIT if it is available (also on non-SMP configurations). Also fixes some general errors in SMP and PIC code as well as some code cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26492 a95241bf-73f2-0310-859d-f6bbb57e9c96

#define B_SAFEMODE_DISABLE_X2APIC "disable_x2apic"
kernel: support for Intel SMAP and SMEP on x86_64. SMAP will generated page faults when the kernel tries to access user pages unless overriden. If SMAP is enabled, the override instructions are written where needed in memory with binary "altcodepatches". Support is enabled by default, might be disabled per safemode setting.

boot/bios_ia32: basic support la57 aka 5-level paging for x86_64 kernels la57 kernel support is required. we simply add a 5th level and enable the cr4 feature. the safemode option "256tb_memory_limit" is named after the 4gb one, but the current support is limited to 512GB as before (this can be later extended).
