Add support for pthread_attr_get/setguardsize()

* Added the aforementioned functions.
* create_area_etc() now takes a guard size parameter.
* The thread_info::stack_base/end range now refers to the usable range
only.

Finished implementation of x86_64 paging.

* vm_init now runs up until create_preloaded_image_areas(), which needs
fixing to handle ELF64.
* Not completely tested. I know Map(), Unmap() and Query() work fine, the
other methods have not been tested as the kernel doesn't boot far enough
for any of them to be called yet. As far as I know they're correct, though.
* Not yet implemented the destructor for X86VMTranslationMap64Bit or Init()
for a user address space.

x86_{read,write}_cr{0,4} can just be implemented as macros, put an x86_ prefix on the other read/write macros for consistency.

Implemented long mode setup/switch code, the bootloader can now start the 64-bit kernel!

The setup procedure is fairly simple: create a 64-bit GDT and 64-bit page
tables that include all kernel mappings from the 32-bit address space, but at
the correct 64-bit address, then go through kernel_args and changes all virtual
addresses to 64-bit addresses, and finally switch to long mode and jump to the
kernel.

* Fixed warnings that occur with GCC4.4.

Removed unnecessary inclusions of <boot/kernel_args.h> in private kernel
headers and respectively added includes in source files.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37259 a95241bf-73f2-0310-859d-f6bbb57e9c96

Disabled tracing and removed a bit of debug output.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37229 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Introduced structures {virtual,physical}_address_restrictions, which specify
restrictions for virtual/physical addresses.
* vm_page_allocate_page_run():
- Fixed conversion of base/limit to array indexes. sPhysicalPageOffset was not
taken into account.
- Takes a physical_address_restrictions instead of base/limit and also
supports alignment and boundary restrictions, now.
* map_backing_store(), VM[User,Kernel]AddressSpace::InsertArea()/
ReserveAddressRange() take a virtual_address_restrictions parameter, now. They
also support an alignment independent from the range size.
* create_area_etc(), vm_create_anonymous_area(): Take
{virtual,physical}_address_restrictions parameters, now.
* Removed no longer needed B_PHYSICAL_BASE_ADDRESS.
* DMAResources:
- Fixed potential overflows of uint32 when initializing from device node
attributes.
- Fixed bounce buffer creation TODOs: By using create_area_etc() with the
new restrictions parameters we can directly support physical high address,
boundary, and alignment.

X86PagingMethodPAE::PutPageTableEntryInTable(): Incorrectly used 32 bit type,
which caused the upper 32 bit of the address to be ignored, thus mapping to
the wrong page.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37104 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added methods {Allocate,Free}32BitPage(), which allocate+map/unmap+free a
page with a 32 bit physical address (needed for the PDPTs). A small set of
free pages is cached, so the rather expensive vm_page_allocate_page_run() can
be avoided most of the time.

Fleshed out most of the unimplemented methods. The kernel boots up to the
creation of the initial shell, now.

Implemented X86PagingMethodPAE::Init() and all of its direct dependencies:
* The 32 bit paging structures inherited from the boot loader are translated
to PAE structures and PAE is enabled.
* Implemented the initialization of the initial PhysicalPageSlotPool, so that
the physical page mapper can be initialized.
