2007-07-16intel-rng: undo mess made by an 80 column extremistAlan Cox1-6/+4
The intel-rng printed a nice well formatted message when the port was disabled. Someone then came along and blindly trashed it by screwing up a trim down to 80 columns. Put it back into the right format and keep the overlong lines as the result is also MUCH easier to read in this specific case.

2007-05-08Use stop_machine_run in the Intel RNG driverPrarit Bhargava1-97/+122
Replace call_smp_function with stop_machine_run in the Intel RNG driver. CPU A has done read_lock(&lock) CPU B has done write_lock_irq(&lock) and is waiting for A to release the lock. A third CPU calls call_smp_function and issues the IPI. CPU A takes CPU C's IPI. CPU B is waiting with interrupts disabled and does not see the IPI. CPU C is stuck waiting for CPU B to respond to the IPI. Deadlock. The solution is to use stop_machine_run instead of call_smp_function (call_smp_function should not be called in situations where the CPUs may be suspended).

2007-05-02PCI: Cleanup the includes of <linux/pci.h>Jean Delvare1-1/+0
I noticed that many source files include <linux/pci.h> while they do not appear to need it. Here is an attempt to clean it all up. In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually. My tests covered 66% of the affected files, so there could be false positives remaining. Untested files are: arch/alpha/kernel/err_common.c arch/alpha/kernel/err_ev6.c arch/alpha/kernel/err_ev7.c arch/ia64/sn/kernel/huberror.c arch/ia64/sn/kernel/xpnet.c arch/m68knommu/kernel/dma.c arch/mips/lib/iomap.c arch/powerpc/platforms/pseries/ras.c arch/ppc/8260_io/enet.c arch/ppc/8260_io/fcc_enet.c arch/ppc/8xx_io/enet.c arch/ppc/syslib/ppc4xx_sgdma.c arch/sh64/mach-cayman/iomap.c arch/xtensa/kernel/xtensa_ksyms.c arch/xtensa/platform-iss/setup.c drivers/i2c/busses/i2c-at91.c drivers/i2c/busses/i2c-mpc.c drivers/media/video/saa711x.c drivers/misc/hdpuftrs/hdpu_cpustate.c drivers/misc/hdpuftrs/hdpu_nexus.c drivers/net/au1000_eth.c drivers/net/fec_8xx/fec_main.c drivers/net/fec_8xx/fec_mii.c drivers/net/fs_enet/fs_enet-main.c drivers/net/fs_enet/mac-fcc.c drivers/net/fs_enet/mac-fec.c drivers/net/fs_enet/mac-scc.c drivers/net/fs_enet/mii-bitbang.c drivers/net/fs_enet/mii-fec.c drivers/net/ibm_emac/ibm_emac_core.c drivers/net/lasi_82596.c drivers/parisc/hppb.c drivers/sbus/sbus.c drivers/video/g364fb.c drivers/video/platinumfb.c drivers/video/stifb.c drivers/video/valkyriefb.c include/asm-arm/arch-ixp4xx/dma.h sound/oss/au1550_ac97.c I would welcome test reports for these files. I am fine with removing the untested files from the patch if the general opinion is that these changes aren't safe. The tested part would still be nice to have.

2007-01-11[PATCH] Fix HWRNG built-in initcalls priorityMichael Buesch5-5/+5
This changes all HWRNG driver initcalls to module_init(). We must probe the RNGs after the major kernel subsystems are already up and running (like PCI).

2007-01-11[PATCH] intel-rng workaroundsJan Beulich1-2/+30
Add a load option to intel-rng to allow skipping the FWH detection, necessary in case the BIOS has locked read-only the firmware hub space. Also prevent any attempt to write to firmware space if it cannot be write enabled (apparently caused hangs on some systems not having an FWH and thus also not having a respective RNG).

2006-09-29[PATCH] fix Intel RNG detectionJan Beulich1-9/+177
Previously, since determination whether there was an Intel random number generator was based on a single bit, on systems with a matching bridge device but without a firmware hub, there was a 50% chance that the code would incorrectly decide that the system had an RNG. This patch adds detection of the firmware hub to better qualify the existence of an RNG. There is one issue with the patch: I was unable to determine the LPC equivalent for the PCI bridge 8086:2430 (since the old code didn't care about which of the many devices provided by the ICH/ESB it was chose to use the PCI bridge device, but the FWH settings live in the LPC device, so the device list needed to be changed).

2006-07-03[PATCH] make more file_operation structs staticArjan van de Ven1-1/+1
Mark the static struct file_operations in drivers/char as const. Making them const prevents accidental bugs, and moves them to the .rodata section so that they no longer do any false sharing; in addition with the proper debug option they are then protected against corruption..
