[PATCH v3 0/2] linux-user: Allow mapping low priority rt signals

[Ilya Leoshkevich <iii@linux.ibm.com>]

v1: Unfortunately lost.

v2: https://lore.kernel.org/qemu-devel/20240212205022.242968-1-iii@linux.ibm.com/
v2 -> v3: Make the mapping configurable (Richard).

Hi,

There are apps out there that want to use SIGRTMAX, which linux-user
currently does not map to a host signal. The reason is that with the
current approach it's not possible to map all target signals, so it
was decided to sacrifice the end of the range.

This series improves the situation by making the mapping configurable.
Patch 1 is the implementation, patch 2 is a test.

Best regards,
Ilya
