5db2971903 base-hw/arm_v7a: Mark r1 as out in Kernel::call64
In case of arm_v7a Kernel::call64 the syscall will use both r0 and r1 as
output registers. Unfortunately the inline asm does not reflect this and
only r0 is explicitly specified as output. GCC manages to produce output
which we'd like to see. Clang on the other hand takes adventage of the fact
r1 should not be touched by swi and produces fewer instructions which do
what the code describes, but not what we actually want.

Basically the code which we want and is generated by GCC is:
  svc     0
  mov     r2, r0
  mov     r0, r1
  mov     r1, r2
  bx      lr

Clang on the other hand generates correct assembly given the code, but
incorrect given what the function is supposed to do:
  svc     0
  mov     r1, r0
  mov     r0, 
  bx      lr

Both GCC and clang generate the same, expected assembly output when r1
is marked as output register from the inline asm swi call.

a892018926 base-hw: Define Entry function as noreturn.
Right now the code marks specific instance of this function as noreturn.
It then tries to initialize it using a value that has the same type,
except for the noreturn part. GCC does not care, but clang complains this
technically assigns the value of entry from incompatible pointer type.

Fix this by defining Entry function as no return.

1643d623e4 base-hw: Fix warning about unused lambda capture
The lambda function passed to Board::Vm_page_table_array does not
actually use "this" for anything. GCC does not warn about this, but
clang does. Remove the extra capture to make clang happy.

9b84a8a402 base-hw: Add semicolons after [[fallthrough]]
GCC doesn't care, but clang complains if [[fallthrough]] is not followed
by a semicolon. Existing code is also not consitent in this regard. Lets
just fix it to make clang happy.

1d826a2c48 base-hw: do direct syscall when run/pause a VCPU
Instead of calling core to run/pause a VCPU, go directly to the kernel.
Apart from the performance win, it would otherwise involve a more complex
protocol, when a VCPU on another core has to be removed from the scheduler.
Core's entrypoint handling those request runs on the boot-cpu only.

40445d7011 base: extend vm_session API with native vcpu cap
To enable the interaction of a VMM with the kernel directly,
a hidden RPC gets introduced. It allows a kernel-specific
base-library implementation of the Vm_session::Client to request
a kernel-specific capability to address a VCPU, e.g., to
run/stop it.

5f5ad41ad3 hw: unify irq enumeration for Raspberri Pi
By now, the enumeration of peripheral interrupts on Raspberry Pi 1 was
different in between base-hw kernel and Fiasco.OC. Therefore, hacks were
needed in every driver to request the correct interrupt number dependent
on the kernel. Before reproducing the same in the platform driver for rpi,
we can more easily use the same enumeration with base-hw.

b134867f31 Remove Rpc_entrypoint::Native_context
This patch largely reverts the commit "base: lay groundwork for
base-linux caps change" because the use of 'epoll' instead of 'select'
alleviated the need to allocate large FD sets, which motivated the
introduction of the 'Native_context' hook.

ff378a8c5b hw: cache maintainance on mapping removal too
Older ARM processors like ARMv6, or Cortex A8 need to write back changes
of the page-tables to physical ram because the MMU does not use the cache.
This naturally needs to be done not only when adding a mapping,
but on removal too.

585c4b8c69 hw: Add support for Qemu virt arm platforms.
This patch adds support for booting base-hw kernel on qemu-arm virt
machines. The arm_virt machine has 2GB of RAM, 2 Cortex A15 cores and
uses GICv2 interrupt controller. The arm_64_virt machine also has 2GB of
RAM, but has 4 Cortex A53 cores and uses GICv3. Both machines use PSCI
to boot additional CPU cores.

0f3ac4cb9f base-hw: let upgrade_cap_slab reflect Out_of_caps
This patch reflects the Out_of_caps exception from core to the client,
in addition to the already covered Out_of_ram exception. It thereby
eliminates a potential abort in core, which I observed with the
tool_chain_auto.run script:

  Kernel: RPC upgrade_cap_slab
  Error: Uncaught exception of type 'Genode::Quota_guard<Genode::Cap_quota>::Limit_exceeded'
  Warning: abort called - thread: entrypoint

In addition to propagating the exception, the patch add the client-side
exception-handling code to the base library.
