2005-08-03[PATCH] fix get_user_pages bugNick Piggin1-5/+17
Checking pte_dirty instead of pte_write in __follow_page is problematic for s390, and for copy_one_pte which leaves dirty when clearing write. So revert __follow_page to check pte_write as before, and make do_wp_page pass back a special extra VM_FAULT_WRITE bit to say it has done its full job: once get_user_pages receives this value, it no longer requires pte_write in __follow_page. But most callers of handle_mm_fault, in the various architectures, have switch statements which do not expect this new case. To avoid changing them all in a hurry, make an inline wrapper function (using the old name) that masks off the new bit, and use the extended interface with double underscores. Yes, we do have a call to do_wp_page from do_swap_page, but no need to change that: in rare case it's needed, another do_wp_page will follow.

2005-08-02[PATCH] increase PCIBIOS_MIN_IO on x86Ivan Kokshaysky2-6/+2
There is a number of x86 laptops that have some non-PCI IO ports in the 0x1000-0x1fff range, and it's quite hard to control the correct order of resource allocation between PCI and other subsystems controlling these ports. Especially with modular kernel. So just increase PCIBIOS_MIN_IO to 0x4000 to prevent any new PCI resource allocations in the problematic range (this limitation must apply _only_ to the root bus resources - see Linus' change in pci_bus_alloc_resource). As PCIBIOS_MIN_IO and PCIBIOS_MIN_CARDBUS_IO are the same now on i386 and x86-64, we can remove the latter.

2005-08-01[PATCH] V4L: Miscellaneous fixesMauro Carvalho Chehab1-1/+3
- Fixed some bttv card numbers. - BTTV and SAA7134 version numbers incremented to reflect changes. - pci_dma_supported() is called after pci_set_dma_mask() which already did check that for us. This patch removes the unneeded call to pci_dma_supported() at bttv-driver.c - Ensure a sufficient I2C bus idle time between 2 messages for saa7134-i2c.c - It is important to write at first to MO_GP3_IO for cx88-tvaudio.c - Use try_to_freeze() instead of refrigerator at msp3400.c - Recognizing the MFPE05-2 Tuner at tveeprom.c - Add new parameter to help identify radio chipsets at tuner module: show_i2c=1 will show 16 reading bytes from detected tuners. - BTTV does generate some Unimplemented IOCTL log at tuner module: 0x40046d11(dir=1,tp=0x6d,nr=17,sz=4) means that it is sending MSP3400 calls to non-msp3400 tuners. Warning eliminated. VIDIOSAUDIO is also called, so debug messages updated. It is still requiring IOCTL implementation. - Added two more tuners. - Add support for the SVideo input on the GDI Black Gold.

2005-07-29[PATCH] Fix sync_tsc hangEric W. Biederman1-0/+3
sync_tsc was using smp_call_function to ask the boot processor to report it's tsc value. smp_call_function performs an IPI_send_allbutself which is a broadcast ipi. There is a window during processor startup during which the target cpu has started and before it has initialized it's interrupt vectors so it can properly process an interrupt. Receveing an interrupt during that window will triple fault the cpu and do other nasty things. Why cli does not protect us from that is beyond me. The simple fix is to match ia64 and provide a smp_call_function_single. Which avoids the broadcast and is more efficient. This certainly fixes the problem of getting stuck on boot which was very easy to trigger on my SMP Hyperthreaded Xeon, and I think it fixes it for the right reasons.

2005-07-28[PATCH] x86_64: Fix gcc 4 warning in sched_find_first_bitJesse Millan1-2/+1
This patch eliminates the GCC4 warning on the x86_64 platform: kernel/sched.c:1824: warning: control may reach end of non-void function 'sched_find_first_bit' being inlined. The change follows the lead of others, i.e. it is guaranteed that at least one of b[0], b[1], or b[2] will have a bit set and evaluate to true. That being said, GCC4.0.0 notices that the code flow does not return anything if b[0], b[1] and b[2] are not true. Since we know better, if it's not b[0] or b[1], it has to be b[2].

2005-07-28Revert broken "statement with no effect" warning fixLinus Torvalds2-23/+6
It may shut up gcc, but it also incorrectly changes the semantics of the smp_call_function() helpers. You can fix the warning other ways if you are interested (create another inline function that takes no arguments and returns zero), but preferably gcc just shouldn't complain about unused return values from statement expressions in the first place.

One might could argue that this is a gcc bug, in that statement-expressions should be considered to be function-like rather than statement-like for the purposes of this warning.
