Partially revert\nthe above git commit and go back to s390 specific page table flush code.\n\nFor s390 the TLB can contain three types of entries, \"normal\" TLB\npage-table entries, TLB combined region-and-segment-table (CRST) entries\nand real-space entries. Linux does not use real-space entries which\nleaves normal TLB entries and CRST entries. The CRST entries are\nintermediate steps in the page-table translation called translation paths.\nFor example a 4K page access in a three-level page table setup will\ncreate two CRST TLB entries and one page-table TLB entry. The advantage\nof that approach is that a page access next to the previous one can reuse\nthe CRST entries and needs just a single read from memory to create the\npage-table TLB entry. The disadvantage is that the TLB flushing rules are\nmore complicated, before any page-table may be freed the TLB needs to be\nflushed.\n\nIn short: the generic RCU page-table freeing code is incorrect for the\nCRST entries, in particular the check for mm_users \u003c 2 is troublesome.\n\nThis is applicable to 3.0+ kernels.\n\nCc: \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "b785e0d06ac551f80204742682be3218158234d1", "tree": "e0128220a97d1e7478c5ae695062ecd18b3a738b", "parents": [ "dae1df42f544ce3969d437dfa835169210593240" ], "author": { "name": "Michael Holzheu", "email": "holzheu@linux.vnet.ibm.com", "time": "Wed Apr 11 14:28:06 2012 +0200" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Wed Apr 11 14:28:24 2012 +0200" }, "message": "[S390] kernel: Use local_irq_save() for memcpy_real()\n\nCurrently in the memcpy_real() function interrupts are disabled with\n__arch_local_irq_stnsm().
