* pc8736x_gpio: depends on X86_32Randy Dunlap2010-08-12
| | | | | | | | | | | | | | | | | Fix kconfig dependency warning for PC8736x_GPIO by restricting it to X86_32. warning: (SCx200_GPIO && SCx200 || PC8736x_GPIO && X86) selects NSC_GPIO which has unmet direct dependencies (X86_32) NSC_GPIO is X86_32 only. The other driver (SCx200_GPIO) that selects NSC_GPIO is X86_32 only (indirectly, since SCx200 depends on X86_32), so limit this driver also.

* char drivers: RAM oops/panic loggerMarco Stornelli2010-05-27
| | | | | | | | | | | | | | | | | | | | | Ramoops, like mtdoops, can log oops/panic information but in RAM. It can be used with persistent RAM for systems without flash support. In addition, for this systems, with this driver, it's no more needed add to the kernel the mtd subsystem with advantage in footprint. It can be used in a very easy way with persistent RAM for systems without flash support. For these systems, with this driver, it is no longer required to cinlude mtd subsystem with an advantage in footprint. In addition, you can save flash space and store this information only in RAM.

| * | powerpc: udbg-based backend for hvc_consoleDavid Gibson2008-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new backend for the hvc console based on the low-level udbg callbacks. This effectively implements a working runtime console in terms of the simple udbg primitives. This is kind of a hack - since udbg isn't something you really want to be using routinely - but it's really useful during bringup. This can be used to quickly implement a userspace-usable console while you're working on a proper driver for whatever console I/O device the hardware has. Or, it can be used to avoid writing a full blown tty/console driver entirely for quick-and-dirty I/O hardware that will later be replaced by something else.

* | | [S390] s390/hvc_console: z/VM IUCV hypervisor console supportHendrik Brueckner2008-12-25
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces a new hypervisor console (HVC) back-end that provides terminal access over the z/VM inter-user communication vehicle (IUCV). The z/VM IUCV communication is independent of the regular tcp/ip network and allows access even if there is no network connection between two z/VM guest virtual machines. The z/VM IUCV hypervisor console back-end helps the user to access a z/VM guest virtual machine that lacks of network connectivity; and thus, provides a "full-screen" terminal alternative to 3215/3270 terminal sessions. Use the hvc_iucv=[0..8] kernel boot parameter to specify the number of HVC terminals using a z/VM IUCV back-end. A recent version of the s390-tools package is required to establish a terminal connection to a z/VM IUCV hypervisor console back-end.

* legacy rtc: remove needless/confusing HPET_RTC_IRQ optionDavid Brownell2008-10-16
| | | | | | | | | | | | | | | | | | | | | | | HPET_RTC_IRQ is no longer needed; HPET_EMULATE_RTC suffices and is more correct. (http://bugzilla.kernel.org/show_bug.cgi?id=11111) Note that when using the legacy RTC driver, platforms don't really do a dynamic switch between HPET and non-HPET modes based on whether HPET hardware actually exists ... only rtc-cmos (using the new RTC framework) currently switches that way. So this reflects bitrot in that legacy code, for x86/ia64: kernels with HPET support configured (e.g. for a clocksource) can't get IRQs from the legacy RTC driver unless they really have HPET hardware. (The obvious workaround is to not use the legacy RTC driver on those platforms when you configure HPET ... unless you know the target really has a HPET.)

This allows virtio_console to use hvc_console without having a linker reference to request_irq/free_irq. In addition, together with patch 2/3 it improves the performance for virtio console input. (an earlier version of this patch was tested by Yajin on lguest) The irq specific code is moved to hvc_irq.c and selected by the drivers that use irqs (System p, System i, XEN). I replaced "int irq" with the opaque "int data". The request_irq and free_irq calls are replaced with notifier_add and notifier_del. I have also changed the code a bit to call the notifier_add and notifier_del inside the spinlock area as the callbacks are found via hp->ops. Changes since last version: o remove ifdef o reintroduce "irq_requested" as "notified" o cleanups, sparse.. I did not move the timer based polling into a separate polling scheme. I played with several variants, but it seems we need to sleep/schedule in a thread even for irq based consoles, as there are throttleing and buffer size constraints. I also kept hvc_struct defined in hvc_console.h so that hvc_irq.c can access the irq_requested element. Feedback is appreciated. virtio_console is currently the only available console for kvm on s390. I plan to push this change as soon as all affected parties agree on it. I would love to get test results from System p, Xen etc. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

* | drivers/char/ip2: fix Kconfig after ip2/ip2main mergeRoland.Kletzing2008-06-06
|/ | | | | | | | | | | | As commit 6089093e588ee3f6aed99d08b1cf5ea37c52cf97 ("ip2: fix crashes on load/unload") fixed the ip2 crashes on load/unload by making ip2/ip2main one module (ip2), Kconfig shouldn't mention a now non-existing module.

* make /dev/kmem a config optionArjan van de Ven2008-04-29
| | | | | | | | | | | | | | | Make /dev/kmem a config option; /dev/kmem is VERY rarely used, and when used, it's generally for no good (rootkits tend to be the most common users). With this config option, users have the choice to disable /dev/kmem, saving some size as well. A patch to disable /dev/kmem has been in the Fedora and RHEL kernels for 4+ years now without any known problems or legit users of /dev/kmem.
