[Minios-devel] [UNIKRAFT PATCH v2 5/7] plat/linuxu: Introduce heap size as a lib parameter

[Sharan Santhanam <sharan.santhanam@xxxxxxxxx>]

In linuxu platform, the user can overwrite the default heap size
parameter. In this patch we introduce the heap size argument as an
UK_LIB_PARAM which the user can modify at boot time.
