Subject: [PATCH v2 03/20] KVM: selftests: Use vm_alloc_page_table() to allocate LoongArch page tables
Date: Wed, 2 Sep 2026 09:41:06 -0700 [thread overview]
Message-ID: <20260902164123.2546762-4-seanjc@google.com> (raw)
In-Reply-To: <20260902164123.2546762-1-seanjc@google.com>
Now that LoongArch uses KVM_GUEST_PAGE_TABLE_MIN_PADDR for its page table
page allocations, 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.
No functional change intended.
