KVM: selftests: Expose align() helpers to tests

2021-11-16T12:43:24Z

Refactor align() to work with non-pointers and split into separate helpers for aligning up vs. down. Add align_ptr_up() for use with pointers. Expose all helpers so that they can be used by tests and/or other utilities. The align_down() helper in particular will be used to ensure gpa alignment for hugepages. No functional change intended. [Added sepearate up/down helpers and replaced open-coded alignment bit math throughout the KVM selftests.] Signed-off-by: Sean Christopherson Signed-off-by: David Matlack Reviewed-by: Ben Gardon Message-Id: <20211111000310.1435032-3-dmatlack@google.com> Signed-off-by: Paolo Bonzini

KVM: selftests: Unconditionally use memslot 0 for vaddr allocations

2021-06-24T15:47:42Z

Drop the memslot param(s) from vm_vaddr_alloc() now that all callers directly specific '0' as the memslot. Drop the memslot param from virt_pgd_alloc() as well since vm_vaddr_alloc() is its only user. I.e. shove the hardcoded '0' down to the vm_phy_pages_alloc() calls. No functional change intended.

KVM: selftests: Unconditionally use memslot 0 when loading elf binary

2021-06-24T08:31:17Z

Use memslot '0' for all vm_vaddr_alloc() calls when loading the test binary. This is the first step toward adding a helper to handle page allocations with a default value for the target memslot. No functional change intended. Signed-off-by: Sean Christopherson Message-Id: <20210622200529.3650424-4-seanjc@google.com> Signed-off-by: Paolo Bonzini
