2008-10-27MIPS: Add CONFIG_CPU_R5500 for NEC VR5500 series processorsShinya Kuribayashi
We already have sufficient infrastructure to support VR5500 and VR5500A series processors. Here's a Makefile support to make it selectable by ports, and enable it for NEC EMMA2RH Markeins board. This patch also fixes a confused target help, and adds 1Gb PageMask bits supported by VR5500 and its variants.

2008-10-03[MIPS] SMTC: Fix SMTC dyntick support.Kevin D. Kissell
Rework of SMTC support to make it work with the new clock event system, allowing "tickless" operation, and to make it compatible with the use of the "wait_irqoff" idle loop. The new clocking scheme means that the previously optional IPI instant replay mechanism is now required, and has been made more robust. Signed-off-by: Kevin D.

2008-07-30[MIPS] kgdb: add arch support for the kernel's kgdb coreJason Wessel
The new kgdb architecture specific handler registers and unregisters dynamically for exceptions depending on when you configure a kgdb I/O driver. Aside from initializing the exceptions earlier in the boot process, kgdb should have no impact on a device when it is compiled in so long as an I/O module is not configured for use. There have been quite a number of contributors during the existence of this patch (see arch/mips/kernel/kgdb.c). Most recently Jason re-wrote the mips kgdb logic to use the die notification handlers.

2008-07-30[MIPS] kgdb: Remove existing implementationJason Wessel

Convert jmr3927_clock_event_device to more generic txx9tmr_clock_event_device which supports one-shot mode. The txx9tmr_clock_event_device can be used for TX49 too if the cp0 timer interrupt was not available. Convert jmr3927_hpt_read to txx9_clocksource driver which does not depends jiffies anymore. The txx9_clocksource itself can be used for TX49, but normally TX49 uses higher precision clocksource_mips.

2007-10-14kbuild: enable 'make CFLAGS=...' to add additional options to CCSam Ravnborg
The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

2006-01-10[PATCH] sanitize building of fs/compat_ioctl.cChristoph Hellwig
Now that all these entries in the arch ioctl32.c files are gone [1], we can build fs/compat_ioctl.c as a normal object and kill tons of cruft. We need a special do_ioctl32_pointer handler for s390 so the compat_ptr call is done. This is not needed but harmless on all other architectures. Also remove some superflous includes in fs/compat_ioctl.c Tested on ppc64. [1] parisc still had it's PPP handler left, which is not fully correct for ppp and besides that ppp uses the generic SIOCPRIV ioctl so it'd kick in for all netdevice users. We can introduce a proper handler in one of the next patch series by adding a compat_ioctl method to struct net_device but for now let's just kill it - parisc doesn't compile in mainline anyway and I don't want this to block this patchset.
