[Xen-devel] [PATCH v4 08/39] arm/p2m: Cosmetic fix - function prototype of p2m_alloc_table

[Sergej Proskurin <proskurin@xxxxxxxxxxxxx>]

The function "p2m_alloc_table" should be able to allocate 2nd stage
translation tables not only for the host's p2m but also for alternate
p2m's.

v2: Removed altp2m table initialization from "p2m_table_init".

v3: Removed initialization of the field d->arch.altp2m_active in
    "p2m_table_init" to avoid altp2m initialization throughout different
    files.

    Merged the function "p2m_alloc_table" and "p2m_table_init".
