Hence, use the IRQ_WORK_INIT_HARD\nvariant so that with PREEMPT_RT kernels, the IRQ work is processed in\nhardirq context instead of being deferred to a thread which is required\nfor calling generic_handle_irq().\n\nOn non-PREEMPT_RT kernels, both init_irq_work() and IRQ_WORK_INIT_HARD()\nexecute in IRQ context, so this change has no functional impact for\nstandard kernel configurations.\n\n[treding@nvidia.com: miscellaneous cleanups]"}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/soc/tegra/pmc.c"],"versions":[{"version":"0474cc8489bda9a8cd6a10252e7e6af29c849438","lessThan":"64016227dcdb968b7030eda04304f3d0df5d209d","status":"affected","versionType":"git"},{"version":"0474cc8489bda9a8cd6a10252e7e6af29c849438","lessThan":"e6d96073af681780820c94079b978474a8a44413","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/soc/tegra/pmc.c"],"versions":[{"version":"6.2","status":"affected"},{"version":"0","lessThan":"6.2","status":"unaffected","versionType":"semver"},{"version":"6.19.6","lessThanOrEqual":"6.19.*","status":"unaffected","versionType":"semver"},{"version":"7.0","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.19.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"7.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/64016227dcdb968b7030eda04304f3d0df5d209d"},{"url":"https://git.kernel.org/stable/c/e6d96073af681780820c94079b978474a8a44413"}],"title":"soc/tegra: pmc: Fix unsafe generic_handle_irq() call","x_generator":{"engine":"bippy-1.2.0"}}}}
