Also, add a bug if a nonlinear condition is encountered\nand can\u0027t be resolved, which might save some hours of debugging if this fragile\nscheme ever breaks again...\n\nOnce we have such logic, we can also use it to eliminate the early ioremap\ntrickery around the page table setup for the fixmap area. This also fixes\npotential issues with FIX_* entries sharing the leaf page table with the early\nioremap ones getting discarded by early_ioremap_clear() and not restored by\nearly_ioremap_reset(). It at once eliminates the temporary (and configuration,\nnamely NR_CPUS, dependent) unavailability of early fixed mappings during the\ntime the fixmap area page tables get constructed.\n\nFinally, also replace the hard coded calculation of the initial table space\nneeded for the fixmap area with a proper one, allowing kernels configured for\nlarge CPU counts to actually boot.\n\nBased-on: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Jan Beulich \u003cjbeulich@novell.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "b5db0e38653bfada34a92f360b4111566ede3842", "tree": "0ebc72a544e3d879ea5f9f57d5f65448d6bf3250", "parents": [ "647df5189fecb2c2fa811421a3f28bf9034e3a70" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 15 15:32:12 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 15 16:25:09 2009 -0800" }, "message": "Revert \"x86 PAT: remove CPA WARN_ON for zero pte\"\n\nThis reverts commit 58dab916dfb57328d50deb0aa9b3fc92efa248ff, which\nmakes my Nehalem come to a nasty crawling almost-halt.
