afcfd3c5d5 BeBuild: Remove B_ALWAYS_INLINE.
This file should ideally contain only those things needed
across all system headers, even POSIX ones, and all other
declarations (B_* ones especially) should go in SupportDefs.h.
However, as nothing but riscv64 uses this right now, I've just
moved it to there.

db9b70ee54 kernel: add a compatibility commpage on x86_64.
* x86 uses a commpage with 32-bit addresses, incompatible with the one used for
x86_64. For this reason, a compatibility commpage is needed to support a 32-bit
userland on x86_64.
* define ADDRESS_TYPE as a macro for addr_t (default) or uint32 (for the 32-bit
commpage).
* team_create_thread_start_internal() will use clone_commpage_area() with
KERNEL_USER_DATA_BASE or clone_commpage_compat_area() with
KERNEL_USER32_DATA_BASE, to setup the correct commpage.
* real_time_clock (in compatibility mode) also updates the compatibility
commpage with real time data.

* add a flag ELF_LOAD_USER_IMAGE_TEST_EXECUTABLE to only check the format.
It will be used by load_image_internal() to check which mode to use when
loading an image.
* in arch_elf_relocate_rel(), switch to elf_addr instead of addr_t, which
would be the wrong size for elf32 on x86_64.
* the ELF compat loader reuses the relevant parts of elf.cpp and arch_elf.cpp,
excluding for instance load_kernel_add_on() or dump functions.

f2f91078bd kernel/x86_64: remove memset and memcpy from commpage
There is absolutely no reason for these functions to be in commpage,
they don't do anything that involves the kernel in any way.

Additionaly, this patch rewrites memset and memcpy to C++, current
implementation is quite simple (though it may perform surprisingly
well when dealing with large buffers on cpus with ermsb). Better
versions are coming soon.

501b24c63b ARM: kernel: Make 32/64-bit atomics work for ARMv5/6
Support for 64-bit atomic operations for ARMv7+ is currently stubbed
out in libroot, but our current targets do not use it anyway.

We now select atomics-as-syscalls automatically based on the ARM
architecture we're building for. The intent is to do away with
most of the board specifics (at the very least on the kernel side)
and just specify the lowest ARMvX version you want to build for.

This will give flexibility in being able to distribute a single
image for a wide range of devices, and building a tuned system
for one specific core type.

e85e399fd7 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.

211f71325a x86: move x86_userspace_thread_exit() from user stack to commpage
x86_userspace_thread_exit() is a stub originally placed at the bottom of
each thread user stack that ensures any thread invokes exit_thread() upon
returning from its main higher level function.

Putting anything that is expected to be executed on a stack causes problems
when implementing data execution prevention. Code of x86_userspace_thread_exit()
is now moved to commpage which seems to be much more appropriate place for it.
