detect SYSENTER/SYSEXIT support on boot
(this serves as a hint for people who try to boot HelenOS on Bochs emulating plain Pentium,
unfortunatelly it also kills VirtualBox, as it does not support SYSENTER/SYSEXIT officially,
see http://www.virtualbox.org/ticket/1248) |

Move multiboot parsing to genarch/*/multiboot and adapt it for use with both ia32 and amd64. Multiboot info parsing now supported on amd64, too. |

There is no need to define ioport{8,16,32}_t types for each architecture separately. |

kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone() |

make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64 |

Introduce ioport8_t, ioport16_t and ioport32_t. These types are to be used with
pio_read_n() and pio_write_n() functions. This breaks everything. |

overhaul pareas: use one single physical area for the physical address space not belonging to physical memory |
|

5624 d 8 h |

/trunk/kernel/ |
Introduce a more platform-neutral name for programmed I/O.
The new API looks like pio_read_n() or pio_write_n(), where n is 8, 16 or 32.
The old API (i.e. inb(), inw(), inl(), outb() outw(), outl()) may have made
some people think that the interface is only to be used with the separate I/O
space. That's not the case. This API is to be implemented on all platforms
so that we can finally have really generic kernel device drivers. |

Some inline functions in memstr.h seem to be of uncertain origin (amd64).
Replace either with built-in functions or with generic functions. |

Each architecture should only announce its endianity.
The conversion macros should be defined only once. |

Fortify ia32 and amd64 kernels against mallicious uspace applications that set
DF prior to entering the kernel. For AMD64 syscalls, we don't use the CLD
instruction, but make use of the SFMASK MSR instead. Simics works fine with
it, but QEMU seems to have a problem. |
