494f881f27 core: don't use frame 0 for managing_system pd
When a PD owns the right to ask for a RAM dataspace's `dma_addr` it is
concurrently constrained to use allocations of a specific physical RAM area.
This commit further limits this area by removing RAM page frame zero.
Otherwise the return value of `dma_addr` for such a dataspace would be
erroneously interpreted as a fault, because zero is currently the error
return value of `dma_addr`.

This is a follow-up fix for "mk/ld.mk: trigger kernel-dependent
ld.lib.so build", which alleviates the need to specify the KERNEL at the

4769e05626 mk: abi does not depend shared-lib dependencies
This patch cuts the superfluous dependency of abi.so files from the
library dependencies of the corresponding lib.so file. ABIs depend
only on symbol files.

Prior this patch, the second step of the following sequence would
wrongly re-build the abi.so file.

  arm_v6$ make init
  arm_v6$ make init KERNEL=hw

As the KERNEL argument does not affect the ABI, the abi.so should
better not be created twice.

300cdc435d expanding_report: make expandable for XML node generation
'generate(Xml_node node)', as used by the Sculpt manager, calls this
function instead of the lambda version. The 'report' function of the
'Genode::Reporter' does not throw an exception in case there is not
enough backing storage for the 'generate' request. Therefore, we have to
check this condition in a loop and call '_increase_report_buffer' in
case size limits are reached.

dd1596aa53 base: Don't produce .gnu.hash tables for Genode.
Genode linker does not support .gnu.hash tables so they will never be
used. Tell the linker not to bother producing them. This should reduce
the size of Genode ELF files a tiny bit without loosing anything

bade0a85e7 base-hw: Implement CPU core identification for Cortex-A55.
According to ARM Cortex-A55 Core Technical Reference Manual r1p0 the
lowest 8 bits (Aff0) of MPIDR register represent thread IDs within a
multi-threaded core. The actual core identification bits are in Aff1.
This layout can be identified by checking the MT bit of MPIDR register.
Basically, if MT=1 core id is in Aff1, if MT=0 core id is in Aff0.

Without this change Genode will identify all CPU cores on A55 as primary
(0) core.

Its worth to mention that Cortex-A55 by itself is not a multi-threaded
CPU. Aff0 values are always expected to be 0 for pure A55 cores. A55
cores can however be paired with cores that are multi-threaded. To
support such big.LITTLE CPUs in Genode we'd probably need to add a
different mechanism for mapping MPIDR values to logical, contignous
core IDs which Genode expects.

58e0b24006 base: Ignore empty constructors array.
This does not affect default Genode builds as far as I can tell. There
is always at least one global static CTOR which seems to be coming from
one of the GCC runtime libs bundled in the toolchain. The problem became
visible for me only after I've replated GCC runtime with LLVM based
one. In such setup I often see binaries that do not have any static ctors.
Such binaries end up crashing Genode ld.lib.so.

Make sure the code does handle empty constructors array.

05e4993d2e gems: Avoid flexible array member in Cached_font.
Switch the code to 0 lengh array instead. The code in
Lru_cache::element_size calls sizeof on this structure. This works in
gcc, but fails when using clang. Even for GCC however the documentation
states:

  "Flexible array members have incomplete type, and so the sizeof operator
   may not be applied. As a quirk of the original implementation of
   zero-length arrays, sizeof evaluates to zero."

Basically its an implementation quirk that clang does not support. Both
GCC and clang do support zero sized arrays however so using them here
allows both compilers to process this code.

5e93a5806b base-hw: Use softfp ABI on virt_qemu ARMv7.
The soft ABI implies purely software floating point implementation.
This is not the case for Genode however. For example core's
exception_vector.S uses vmsr instruction. This builds fine with with
GCC based toolchain, but clang with integrated-as complains:

src/core/spec/arm/exception_vector.S:122:2: error: instruction requires: VFP2
 vmsr fpexc, r1
 ^

Fix this by passing softfp to mfloat-abi command on ARMv7. This allows
usage of FP HW, but implies soft-floating point ABI.

4ae78639f5 base-hw: Fix invalid structure alignments.
According to C++11 reference:

  "If the strictest (largest) alignas on a declaration is weaker than
   the alignment it would have without any alignas specifiers (that is,
   weaker than its natural alignment or weaker than alignas on another
   declaration of the same object or type), the program is ill-formed:"

https://en.cppreference.com/w/cpp/language/alignas

The code requests 4 byte alignment for Genode::Arm_cpu::Context.
The Context structure inherits Genode::Arm_cpu::Fpu_context which
has minimum alignment requirement of 8 bytes, due to uint64_t d0_d31
member. This makes the 4 byte value in Context's alignas specifier
invalid (smaller than allowed minimum).

Similar situation takes place in Arm_64 case. The claimed minimum
alignment of Context is 8 bytes, but the fpu_state member imposes 16
bytes alignment (explicitly specified in Fpu_state declaration).

In both cases the code builds fine with GCC 8.3.0, but fails with
clang which claims that "requested alignment is less than minimum
alignment of X for type", where X is 8 on ARM and 16 on AArch64.
