** Description changed: SRU Justification [Impact] - NVIDIA kernels are used on systems that require support for the - Microsoft Azure Network Adapter, including on ARM64 systems with support - for 64K and 4K page sizes. Systems using MANA may also need to support - booting from it. Build the MANA driver on both arches and include the - listed fixes for the MANA driver to support both 64K and 4K page sizes - and address a race condition. + NVIDIA kernels are used on systems that require support for the Microsoft Azure + Network Adapter, including on ARM64 systems with support for 64K and 4K page + sizes.
