Subject: [PATCH 03/20] KVM: selftests: Use vm_alloc_page_table() to allocate LoongArch page tables
Date: Wed, 26 Aug 2026 16:04:54 -0700 [thread overview]
Message-ID: <20260826230511.972824-4-seanjc@google.com> (raw)
In-Reply-To: <20260826230511.972824-1-seanjc@google.com>
Now that KVM_GUEST_PAGE_TABLE_MIN_PADDR == LOONGARCH_PAGE_TABLE_PHYS_MIN,
use the common vm_alloc_page_table() instead of open coding the same.
Opportunistically drop the assert that the allocation succeeded, as the
allocator itself guarantees success.
For all intents and purposes, no functional change intended.
