iommu/amd: Do not reallocate GA log buffers on resume
In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Do not reallocate GA log buffers on resume Commit c5e1a1eb9279 ("iommu/amd: Simplify and Consolidate Virtual APIC (AVIC) Enablement") moved the GA log allocation from iommu_init_pci() to enable_iommus_vapic(), which is called on every resume. iommu_init_ga_log() assigns iommu->ga_log and iommu->ga_log_tail unconditionally. Each resume therefore replaces the boot-time pointers and leaks both old allocations. The function also uses GFP_KERNEL from a syscore resume callback, where interrupts are disabled and the non-boot CPUs are offline. Return early if both buffers are already allocated. Clear the pointers in free_ga_log() so a partial allocation failure cannot leave ga_log dangling.
