On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386.

With slab debugging turned\non, the slab is still aligned, but the \"working\" object pointer is not.\nThis would break the assumption above that a full nibble is available for\nthe PGF_CACHENUM_MASK.\n\nThe following patch reduces PGF_CACHENUM_MASK to cover only the two least\nsignificant bits, which is enough to cover the current number of 4 pgtable\ncache types. Then use this constant to mask out the appropriate part of\nthe huge pte pointer.\n\nSigned-off-by: Adam Litke \u003cagl@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "c4342ff92bed26f2e0e3543a9f0fdc5f3a29b8fd", "tree": "1e79e4a33cd9a5e19d7143d6fed20bed9e3adc3a", "parents": [ "6cdd2bdfb9e2449f1c8a0f729cdf9cfd733dd63f" ], "author": { "name": "Zang Roy-r61911", "email": "tie-fei.zang@freescale.com", "time": "Wed Aug 23 10:19:50 2006 +0800" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Wed Aug 23 15:51:18 2006 +1000" }, "message": "[POWERPC] Update mpc7448hpc2 board irq support using device tree\n\nThe patch rewrites mpc7448hpc2 board irq support according to the new\nmpic device tree interface.\n\nSigned-off-by: Roy Zang\t\u003ctie-fei.zang@freescale.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "5db9fa9593e2ff69f2b95f9d59229dc4faaa564d", "tree": "d58ba58c05408edf8993d0da5a31b3ea3df1a053", "parents": [ "aa74a30be971c632d734e487df42278b1cf85151" ], "author": { "name": "Nathan Lynch", "email": "ntl@pobox.com", "time": "Tue Aug 22 20:36:05 2006 -0500" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Wed Aug 23 15:51:18 2006 +1000" }, "message": "[POWERPC] Fix gettimeofday inaccuracies\n\nThere are two problems in the powerpc gettimeofday code which can\ncause incorrect results to be returned.\n\nThe first is that there is a race between do_gettimeofday and the\ntimer interrupt:\n\n1. do_gettimeofday does get_tb()\n\n2. decrementer exception on boot cpu which runs timer_recalc_offset,\n which also samples the timebase and updates the do_gtod structure\n with a greater timebase value.\n\n3. do_gettimeofday calls __do_gettimeofday, which leads to the\n negative result from tb_val - temp_varp-\u003etb_orig_stamp.\n\nThe second is caused by taking the boot cpu offline, which can cause\nthe value of tb_last_jiffy to be increased past the currently\navailable timebase, causing the same underflow as above.\n\n[paulus@samba.org - define and use data_barrier() instead of mb().]\n\nSigned-off-by: Nathan Lynch \u003cntl@pobox.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "499792ec6dc737467e5486527cef95ed7d74fba9", "tree": "b88c4ef9d4491c17f71d26d33e73f05f7c7ea6a0", "parents": [ "421b20b9c44b3fcdc07d6af875dad5ae86fad014", "d14b50cc60ca465290fcdb3b88e7d5fb684361ed" ], "author": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Sat Aug 19 17:27:27 2006 -0400" }, "committer": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Sat Aug 19 17:27:27 2006 -0400" }, "message": "Merge branch \u0027upstream-fixes\u0027 into upstream\n" }, { "commit": "b6f35b4966e0ae59cec45e5292b100698d12dc5f", "tree": "5ff3b2832c1c3eebbef699df710068ab106ab2db", "parents": [ "47585d8f5dea10dea49c948f1fb13ef7632409c7" ], "author": { "name": "Michael Ellerman", "email": "michael@ellerman.id.au", "time": "Wed Jul 05 14:39:43 2006 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Thu Aug 17 16:41:10 2006 +1000" }, "message": "[POWERPC] Make crash.c work on 32-bit and 64-bit\n\nTo compile kexec on 32-bit we need a few more bits and pieces.
