An IMSIC address is only set after a vCPU exists, which already freezes the selected GPA width. APLIC can be configured earlier, so its range is rechecked at init. Patch 2 keeps the previously reviewed GPA-width freeze unchanged. Changes since v1: https://lore.kernel.org/r/cover.1786512671.git.pengpeng@iscas.ac.cn/ - Preserve the required-address checks and existing cleanup path. - Remove the all-vCPU range-validation pass. - Explain why only APLIC needs a range recheck before initialization. - Retain Anup's Reviewed-by for unchanged patch 2. The issues were found by our static-analysis tool. AI assistance was used to revise the patches and descriptions following the review.
