Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:
Wade reported a compile error of el6 kernel on Fedora
arch/x86/include/asm/pgtable_64.h:98:20: warning: conflicting types for ‘native_pmd_clear’ [enabled by default]
arch/x86/include/asm/pgtable_64.h:98:20: error: static declaration of ‘native_pmd_clear’ follows non-static declaration
arch/x86/include/asm/pgtable_64.h:87:2: note: previous implicit declaration of ‘native_pmd_clear’ was here
which is caused by the following commit:
commit 27473d67d4d15abf02179c99d9e02ef72e0c478a

[mm] add pmd mangling functions to x86
This is due to,
+#ifdef CONFIG_SMP
+ return native_make_pmd(xchg(&xp->pmd, 0));
+#else
+ /* native_local_pmdp_get_and_clear,
+ but duplicated because of cyclic dependency */
+ pmd_t ret = *xp;
+ native_pmd_clear(NULL, 0, xp); <============= This line
+ return ret;
+#endif
while the prototype of native_pmd_clear() is
static inline void native_pmd_clear(pmd_t *pmd)
Additional info:
Since we don't support modified .config, this problem is not serious.
