2008-07-24add HAVE_CLK to Kconfig, for driver dependenciesDavid Brownell
Flag platforms as HAVE_CLK (or not) in Kconfig, based on whether they support <linux/clk.h> calls, so that otherwise portable drivers which need those calls can list that dependency. Something like this is a prerequisite for merging the musb_hdrc driver, currently used on platforms including Davinci, OMAP2430, OMAP3xx ... and the discrete TUSB6010 chip, which doesn't have a natural platform dependency. (Used with OMAP 2420 in current Nokia N8x0 tablets.)

2008-07-24mv643xx_eth: use auto phy polling for configuring (R)(G)MII interfaceLennert Buytenhek
The mv643xx_eth hardware has a provision for polling the PHY's MII management registers to obtain the (R)(G)MII interface speed (10/100/1000) and duplex (half/full) and pause (off/symmetric) settings to use to talk to the PHY. The driver currently does not make use of this feature. Instead, whenever there is a link status change event, it reads the current link parameters from the PHY, and programs those parameters into the mv643xx_eth MAC by hand. This patch switches the mv643xx_eth driver to letting the MAC auto-determine the (R)(G)MII link parameters by PHY polling, if there is a PHY present. For PHYless ports (when e.g. the (R)(G)MII interface is connected to a hardware switch), we keep hardcoding the MII interface parameters. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>

2008-07-23kgdb: support for ARCH=armJason Wessel
This patch adds the ARCH=arm specific a kgdb backend, originally written by Deepak Saxena <dsaxena@plexity.net> and George Davis <gdavis@mvista.com>. Geoff Levand <geoffrey.levand@am.sony.com>, Nicolas Pitre, Manish Lachwani, and Jason Wessel have contributed various fixups here as well. The KGDB patch makes one change to the core ARM architecture such that the traps are initialized early for use with the debugger or other subsystems.

2008-07-21sysdev: Pass the attribute to the low level sysdev show/store functionAndi Kleen
This allow to dynamically generate attributes and share show/store functions between attributes. Right now most attributes are generated by special macros and lots of duplicated code. With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype. It's a single huge patch to avoid unbisectable sections.

2008-07-18nohz: prevent tick stop outside of the idle loopThomas Gleixner
Jack Ren and Eric Miao tracked down the following long standing problem in the NOHZ code: scheduler switch to idle task enable interrupts Window starts here ----> interrupt happens (does not set NEED_RESCHED) irq_exit() stops the tick ----> interrupt happens (does set NEED_RESCHED) return from schedule() cpu_idle(): preempt_disable(); Window ends here The interrupts can happen at any point inside the race window. The first interrupt stops the tick, the second one causes the scheduler to rerun and switch away from idle again and we end up with the tick disabled. The fact that it needs two interrupts where the first one does not set NEED_RESCHED and the second one does made the bug obscure and extremly hard to reproduce and analyse. Kudos to Jack and Eric. Solution: Limit the NOHZ functionality to the idle loop to make sure that we can not run into such a situation ever again. cpu_idle() { preempt_disable(); while(1) { tick_nohz_stop_sched_tick(1); <- tell NOHZ code that we are in the idle loop while (!need_resched()) halt(); tick_nohz_restart_sched_tick(); <- disables NOHZ mode preempt_enable_no_resched(); schedule(); preempt_disable(); } } In hindsight we should have done this forever, but ... /me grabs a large brown paperbag.
