2009-11-03PM / yenta: Split resume into early and late parts (rev. 4)Rafael J. Wysocki
Commit 0c570cdeb8fdfcb354a3e9cd81bfc6a09c19de0c (PM / yenta: Fix cardbus suspend/resume regression) caused resume to fail on systems with two CardBus bridges. While the exact nature of the failure is not known at the moment, it can be worked around by splitting the yenta resume into an early part, executed during the early phase of resume, that will only resume the socket and power it up if there was a card in it during suspend, and a late part, executed during "regular" resume, that will carry out all of the remaining yenta resume operations. Fixes http://bugzilla.kernel.org/show_bug.cgi?id=14334, which is a listed regression from 2.6.31. Signed-off-by: Rafael J.

2009-09-29PM / PCMCIA: Drop second argument of pcmcia_socket_dev_suspend()Rafael J. Wysocki
pcmcia_socket_dev_suspend() doesn't use its second argument, so it may be dropped safely. This change is necessary for the subsequent yenta suspend/resume fix. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Cc: stable@kernel.org

CS_BAD_TYPE was only used in cs.c and already properly annotated by error messages. CS_BAD_ATTRIBUTE and CS_BAD_PAGE mean a badly written driver, so ds_dbg() output and -EINVAL seems to be enough.

This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places.

2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki
Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

2007-05-02PCI: Cleanup the includes of <linux/pci.h>Jean Delvare
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.

Remove all references to PF_FREEZE and PF_FROZEN from all kernel sources except sched.h 3. Fix numerous locations where try_to_freeze is manually done by a driver 4. Remove the argument that is no longer necessary from two function calls. 5. Some whitespace cleanup 6. Clear potential race in refrigerator (provides an open window of PF_FREEZE cleared before setting PF_FROZEN, recalc_sigpending does not check PF_FROZEN). This patch does not address the problem of freeze_processes() violating the rule that a task may only modify its own flags by setting PF_FREEZE.

2005-06-23[PATCH] yenta TI: turn off interrupts during card power-on #2Daniel Ritz
- make boot-up card recognition more reliable (ie. redo interrogation always if there is no valid 'card inserted' state) (and yes, i saw it happening on an o2micro controller that both CB_CBARD and CB_16BITCARD bits were set at the same time) - also redo interrogation before probing the ISA interrupts. it's safer to do the probing with the socket in a clean state. - make card insert detect more reliable. yenta_get_status() now returns SS_PENDING as long as the card is not completley inserted and one of the voltage bits is set. also !CB_CBARD doesn't mean CB_16BITCARD. there is CB_NOTACARD as well, so make an explicit check for CB_16BITCARD. - for TI bridges: disable IRQs during power-on. in all-serial and tied interrupt mode the interrupts are always disabled for single-slot controllers. for two-slot contollers the disabling is only done when the other slot is empty. to force disabling there is a new module parameter now: pwr_irqs_off=Y (which is a regression for working setups. that's why it's an option, only use when required) - modparm to disable ISA interrupt probing (isa_probe, defaults to on) - remove unneeded code/cleanups (ie. merge yenta_events() into yenta_interrupts()) Signed-off-by: Daniel Ritz <daniel.ritz@gmx.ch> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
