-/**
- * Whitelist to allow certain references to pass with no warning.
- *
- * Pattern 1:
- * If a module parameter is declared __initdata and permissions=0
- * then this is legal despite the warning generated.
- * We cannot see value of permissions here, so just ignore
- * this pattern.
- * The pattern is identified by:
- * tosec = .init.data
- * fromsec = .data*
- * atsym =__param*
- *
- * Pattern 1a:
- * module_param_call() ops can refer to __init set function if permissions=0
- * The pattern is identified by:
- * tosec = .init.text
- * fromsec = .data*
- * atsym = __param_ops_*
- *
- * Pattern 2:
- * Many drivers utilise a *driver container with references to
- * add, remove, probe functions etc.
- * the pattern is identified by:
- * tosec = init or exit section
- * fromsec = data section
- * atsym = *driver, *_template, *_sht, *_ops, *_probe,
- * *probe_one, *_console, *_timer
- *
- * Pattern 3:
- * Whitelist all references from .head.text to any init section
- *
- * Pattern 4:
- * Some symbols belong to init section but still it is ok to reference
- * these from non-init sections as these symbols don't have any memory
- * allocated for them and symbol address and value are same. So even
- * if init section is freed, its ok to reference those symbols.
- * For ex. symbols marking the init section boundaries.
- * This pattern is identified by
- * refsymname = __init_begin, _sinittext, _einittext
- *
- * Pattern 5:
- * GCC may optimize static inlines when fed constant arg(s) resulting
- * in functions like cpumask_empty() -- generating an associated symbol
- * cpumask_empty.constprop.3 that appears in the audit. If the const that
- * is passed in comes from __init, like say nmi_ipi_mask, we get a
- * meaningless section warning. May need to add isra symbols too...
- * This pattern is identified by
- * tosec = init section
- * fromsec = text section
- * refsymname = *.constprop.*
- *
- * Pattern 6:
- * Hide section mismatch warnings for ELF local symbols. The goal
- * is to eliminate false positive modpost warnings caused by
- * compiler-generated ELF local symbol names such as ".LANCHOR1".
- * Autogenerated symbol names bypass modpost's "Pattern 2"
- * whitelisting, which relies on pattern-matching against symbol
- * names to work. (One situation where gcc can autogenerate ELF
- * local symbols is when "-fsection-anchors" is used.)

+ * cpumask_empty.constprop.3 that appears in the audit. If the const that
+ * is passed in comes from __init, like say nmi_ipi_mask, we get a
+ * meaningless section warning. May need to add isra symbols too...
+ * This pattern is identified by
+ * tosec = init section
+ * fromsec = text section
+ * refsymname = *.constprop.*
+ *
+ * Pattern 6:
+ * Hide section mismatch warnings for ELF local symbols. The goal
+ * is to eliminate false positive modpost warnings caused by
+ * compiler-generated ELF local symbol names such as ".LANCHOR1".
+ * Autogenerated symbol names bypass modpost's "Pattern 2"

+ * names to work. (One situation where gcc can autogenerate ELF
+ * local symbols is when "-fsection-anchors" is used.)

+ * Whitelist to allow certain references to pass with no warning.
+ *
+ * Pattern 1:
+ * If a module parameter is declared __initdata and permissions=0
+ * then this is legal despite the warning generated.
+ * We cannot see value of permissions here, so just ignore
+ * this pattern.
+ * The pattern is identified by:
+ * tosec = .init.data
+ * fromsec = .data*
+ * atsym =__param*
+ *
+ * Pattern 1a:
+ * module_param_call() ops can refer to __init set function if permissions=0
+ * The pattern is identified by:
+ * tosec = .init.text
+ * fromsec = .data*
+ * atsym = __param_ops_*
+ *
+ * Pattern 2:
+ * Many drivers utilise a *driver container with references to
+ * add, remove, probe functions etc.
+ * the pattern is identified by:
+ * tosec = init or exit section
+ * fromsec = data section
+ * atsym = *driver, *_template, *_sht, *_ops, *_probe,
+ * *probe_one, *_console, *_timer
+ *
+ * Pattern 3:
+ * Whitelist all references from .head.text to any init section
+ *
+ * Pattern 4:
+ * Some symbols belong to init section but still it is ok to reference
+ * these from non-init sections as these symbols don't have any memory
+ * allocated for them and symbol address and value are same. So even
+ * if init section is freed, its ok to reference those symbols.
+ * For ex. symbols marking the init section boundaries.
+ * This pattern is identified by
+ * refsymname = __init_begin, _sinittext, _einittext
+ *
+ * Pattern 5:
+ * GCC may optimize static inlines when fed constant arg(s) resulting
+ * in functions like cpumask_empty() -- generating an associated symbol
+ * cpumask_empty.constprop.3 that appears in the audit. If the const that
+ * is passed in comes from __init, like say nmi_ipi_mask, we get a
+ * meaningless section warning. May need to add isra symbols too...
+ * This pattern is identified by
+ * tosec = init section
+ * fromsec = text section
+ * refsymname = *.constprop.*
+ *
+ * Pattern 6:
+ * Hide section mismatch warnings for ELF local symbols. The goal
+ * is to eliminate false positive modpost warnings caused by
+ * compiler-generated ELF local symbol names such as ".LANCHOR1".
+ * Autogenerated symbol names bypass modpost's "Pattern 2"
+ * whitelisting, which relies on pattern-matching against symbol
+ * names to work. (One situation where gcc can autogenerate ELF
+ * local symbols is when "-fsection-anchors" is used.)

+ * this pattern.
+ * The pattern is identified by:
+ * tosec = .init.data
+ * fromsec = .data*
+ * atsym =__param*
+ *
+ * Pattern 1a:
+ * module_param_call() ops can refer to __init set function if permissions=0
+ * The pattern is identified by:
+ * tosec = .init.text
+ * fromsec = .data*
+ * atsym = __param_ops_*
+ *
+ * Pattern 3:
+ * Whitelist all references from .head.text to any init section
+ *
+ * Pattern 4:
+ * Some symbols belong to init section but still it is ok to reference
+ * these from non-init sections as these symbols don't have any memory
+ * allocated for them and symbol address and value are same. So even
+ * if init section is freed, its ok to reference those symbols.
+ * For ex. symbols marking the init section boundaries.
+ * This pattern is identified by
+ * refsymname = __init_begin, _sinittext, _einittext
+ *
+ * Pattern 5:
+ * GCC may optimize static inlines when fed constant arg(s) resulting
+ * in functions like cpumask_empty() -- generating an associated symbol
+ * cpumask_empty.constprop.3 that appears in the audit. If the const that
+ * is passed in comes from __init, like say nmi_ipi_mask, we get a
+ * meaningless section warning. May need to add isra symbols too...
+ * This pattern is identified by
+ * tosec = init section
+ * fromsec = text section
+ * refsymname = *.constprop.*
+ *
+ * Pattern 6:
+ * Hide section mismatch warnings for ELF local symbols. The goal
+ * is to eliminate false positive modpost warnings caused by
+ * compiler-generated ELF local symbol names such as ".LANCHOR1".
+ * Autogenerated symbol names bypass modpost's "Pattern 2"
+ * whitelisting, which relies on pattern-matching against symbol
+ * names to work. (One situation where gcc can autogenerate ELF
+ * local symbols is when "-fsection-anchors" is used.)

-/**
- * Whitelist to allow certain references to pass with no warning.
- *
- * Pattern 1:
- * If a module parameter is declared __initdata and permissions=0
- * then this is legal despite the warning generated.
- * We cannot see value of permissions here, so just ignore
- * this pattern.
- * The pattern is identified by:
- * tosec = .init.data
- * fromsec = .data*
- * atsym =__param*
- *
- * Pattern 1a:
- * module_param_call() ops can refer to __init set function if permissions=0
- * The pattern is identified by:
- * tosec = .init.text
- * fromsec = .data*
- * atsym = __param_ops_*
- *
- * Pattern 3:
- * Whitelist all references from .head.text to any init section
- *
- * Pattern 4:
- * Some symbols belong to init section but still it is ok to reference
- * these from non-init sections as these symbols don't have any memory
- * allocated for them and symbol address and value are same. So even
- * if init section is freed, its ok to reference those symbols.
- * For ex. symbols marking the init section boundaries.
- * This pattern is identified by
- * refsymname = __init_begin, _sinittext, _einittext
- *
- * Pattern 5:
- * GCC may optimize static inlines when fed constant arg(s) resulting
- * in functions like cpumask_empty() -- generating an associated symbol
- * cpumask_empty.constprop.3 that appears in the audit. If the const that
- * is passed in comes from __init, like say nmi_ipi_mask, we get a
- * meaningless section warning. May need to add isra symbols too...
- * This pattern is identified by
- * tosec = init section
- * fromsec = text section
- * refsymname = *.constprop.*
- *
- * Pattern 6:
- * Hide section mismatch warnings for ELF local symbols. The goal
- * is to eliminate false positive modpost warnings caused by
- * compiler-generated ELF local symbol names such as ".LANCHOR1".
- * Autogenerated symbol names bypass modpost's "Pattern 2"
- * whitelisting, which relies on pattern-matching against symbol
- * names to work. (One situation where gcc can autogenerate ELF
- * local symbols is when "-fsection-anchors" is used.)

+ * The pattern is identified by:
+ * tosec = .init.data
+ * fromsec = .data*
+ * atsym =__param*
+ *
+ * Pattern 1a:
+ * module_param_call() ops can refer to __init set function if permissions=0
+ * The pattern is identified by:
+ * tosec = .init.text
+ * fromsec = .data*
+ * atsym = __param_ops_*
+ *
+ * Pattern 3:
+ * Whitelist all references from .head.text to any init section
+ *
+ * Pattern 4:
+ * Some symbols belong to init section but still it is ok to reference
+ * these from non-init sections as these symbols don't have any memory
+ * allocated for them and symbol address and value are same. So even
+ * if init section is freed, its ok to reference those symbols.
+ * For ex. symbols marking the init section boundaries.
+ * This pattern is identified by
+ * refsymname = __init_begin, _sinittext, _einittext
+ *
+ * Pattern 5:
+ * GCC may optimize static inlines when fed constant arg(s) resulting
+ * in functions like cpumask_empty() -- generating an associated symbol
+ * cpumask_empty.constprop.3 that appears in the audit. If the const that
+ * is passed in comes from __init, like say nmi_ipi_mask, we get a
+ * meaningless section warning. May need to add isra symbols too...
+ * This pattern is identified by
+ * tosec = init section
+ * fromsec = text section
+ * refsymname = *.constprop.*
+ *
+ * Pattern 6:
+ * Hide section mismatch warnings for ELF local symbols. The goal
+ * is to eliminate false positive modpost warnings caused by
+ * compiler-generated ELF local symbol names such as ".LANCHOR1".
+ * Autogenerated symbol names bypass modpost's "Pattern 2"
+ * whitelisting, which relies on pattern-matching against symbol
+ * names to work. (One situation where gcc can autogenerate ELF
+ * local symbols is when "-fsection-anchors" is used.)
