* MAINTAINERS: update email and git treeMauro Carvalho Chehab2012-10-251-22/+22
| | | | | | | | | | | | While mchehab@infradead.org is valid, I prefer to use just one email for all patches upstream, instead of receiving some things on one emails, and others on some other place. While here, also update the main linux-media development tree, as the one at kernel.org is used mainly for patch merging and it is generally delayed.

It should also be opened for digital TV. As there are other I2C devices there (flash devices, etc) that aren't related to either one, it is better to make it generic enough to open for all media devices with video.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split the Kconfig option CONFIG_MIPS_MT_SMP into CONFIG_MIPS_MT_SMP and CONFIG_MIPS_PERF_SHARED_TC_COUNTERS so some of the code used for performance counters that are shared between threads can be used for MIPS cores that are not MT_SMP.

| | * | MIPS: perf: Remove unnecessary #ifdefAl Cooper2012-10-111-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The #ifdef for CONFIG_HW_PERF_EVENTS is not needed because the Makefile will only compile the module if this config option is set. This means that the code under #else would never be compiled. This may have been done to leave the original broken code around for reference, but the FIXME comment above the code already shows the broken code.

| | * | MIPS: perf: Add cpu feature bit for PCI (performance counter interrupt)Al Cooper2012-10-115-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PCI (Program Counter Interrupt) bit in the "cause" register is mandatory for MIPS32R2 cores, but has also been added to some R1 cores (BMIPS5000). This change adds a cpu feature bit to make it easier to check for and use this feature.
