2008-08-12modules: extend initcall_debug functionality to the module loaderArjan van de Ven
The kernel has this really nice facility where if you put "initcall_debug" on the kernel commandline, it'll print which function it's going to execute just before calling an initcall, and then after the call completes it will 1) print if it had an error code 2) checks for a few simple bugs (like leaving irqs off) and 3) print how long the init call took in milliseconds. While trying to optimize the boot speed of my laptop, I have been loving number 3 to figure out what to optimize... ... and then I wished that the same thing was done for module loading. This patch makes the module loader use this exact same functionality; it's a logical extension in my view (since modules are just sort of late binding initcalls anyway) and so far I've found it quite useful in finding where things are too slow in my boot.

2008-08-12intel/agp: rewrite GTT on resumeKeith Packard
On my Intel chipset (965GM), the GTT is entirely erased across suspend/resume. This patch simply re-plays the current mapping at resume time to restore the table.=20 I noticed this once I started relying on persistent GTT mappings across VT switch in our GEM work -- the old X server and DRM code carefully unbind all memory from the GTT on VT switch, but GEM does not bother. I placed the list management and rewrite code in the generic layer on the assumption that it will be needed on other hardware, but I did not add the rewrite call to anything other than the Intel resume function. Keep a list of current GATT mappings. At resume time, rewrite them into the GATT. This is needed on Intel (at least) as the entire GATT is cleared across suspend/resume.

As pointed out and tracked by Yinghai Lu <yhlu.kernel@gmail.com>: Dhaval Giani got: kernel BUG at arch/x86/kernel/io_apic_64.c:357! invalid opcode: 0000 [1] SMP CPU 24 ... his system (x3950) has 8 ioapic, irq > 256 This was caused by: commit 9b7dc567d03d74a1fbae84e88949b6a60d922d82 Author: Thomas Gleixner <tglx@linutronix.de> Date: Fri May 2 20:10:09 2008 +0200 x86: unify interrupt vector defines The interrupt vector defines are copied 4 times around with minimal differences. Move them all into asm-x86/irq_vectors.h It appears that Thomas did not notice that x86_64 does something completely different when he merge irq_vectors.h We can solve this for 2.6.27 by simply reintroducing the old heuristic for setting NR_IRQS on x86_64 to a usable value, which trivially removes the regression. Long term it would be nice to harmonize the handling of ioapic interrupts of x86_32 and x86_64 so we don't have this kind of confusion. Dhaval Giani <dhaval@linux.vnet.ibm.com> tested an earlier version of this patch by YH which confirms simply increasing NR_IRQS fixes the problem. Signed-off-by: Eric W.

2008-08-07tracehook: fix CLONE_PTRACERoland McGrath
In the change in commit 09a05394fe2448a4139b014936330af23fa7ec83, I overlooked two nits in the logic and this broke using CLONE_PTRACE when PTRACE_O_TRACE* are not being used. A parent that is itself traced at all but not using PTRACE_O_TRACE*, using CLONE_PTRACE would have its new child fail to be traced. A parent that is not itself traced at all that uses CLONE_PTRACE (which should be a no-op in this case) would confuse the bookkeeping and lead to a crash at exit time. This restores the missing checks and fixes both failure modes. Reported-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Roland McGrath <roland@redhat.com>

Export pci_pme_active() to drivers, so that they can clear the PME_status bit and disable PME# for their devices without involving ACPI. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2008-08-07PCI: make pci_register_driver() a macroAndrew Morton
alpha: CC [M] drivers/usb/gadget/u_ether.o In file included from include/asm/dma-mapping.h:7, from include/linux/dma-mapping.h:52, from include/linux/dmaengine.h:29, from include/linux/skbuff.h:29, from include/linux/if_ether.h:114, from include/linux/etherdevice.h:27, from drivers/usb/gadget/u_ether.c:29: include/linux/pci.h: In function 'pci_register_driver': include/linux/pci.h:673: error: 'KBUILD_MODNAME' undeclared (first use in this function) include/linux/pci.h:673: error: (Each undeclared identifier is reported only once include/linux/pci.h:673: error: for each function it appears in.) Sam says: The problem is that u_ether.o is used by two modules so when we build it KBUILD_MODNAME is not defined because kbuild does not know what value to use. And in pci.h we have the following inline: static inline int __must_check pci_register_driver(struct pci_driver *driver) { return __pci_register_driver(driver, THIS_MODULE, KBUILD_MODNAME); } And alpha uses dma-mapping.h to nullify a number of functions that seem to require something from pci.h. Making it a macro fixes this particular problem. However, the underlying issue of a file using KBUILD_MODNAME and being shared between multiple modules is *not* addressed. I guess the answer there is "don't do that".
