Subject: [kvm PATCH v4 0/2] use vmalloc to allocate vmx vcpus
Date: Fri, 26 Oct 2018 00:58:58 -0700	[thread overview]
Message-ID: <20181026075900.111462-1-marcorr@google.com> (raw)

A couple of patches to allocate vmx vcpus with vmalloc instead of
kalloc, which enables vcpu allocation to succeeed when contiguous
physical memory is sparse.

Compared to the last version of these patches, this version:
1. Splits out the refactoring of the vmx_msrs struct into it's own
patch, as suggested by Sean Christopherson <sean.j.christopherson@intel.com>.
2. Leverages the __vmalloc() API rather than introducing a new vzalloc()
API, as suggested by Michal Hocko <mhocko@kernel.org>.

  kvm: vmx: refactor vmx_msrs struct for vmalloc
  kvm: vmx: use vmalloc() to allocate vcpus
