2009-08-07USB: musb: fix the nop registration for OMAP3EVMGupta, Ajay Kumar
OMAP3EVM uses ISP1504 phy which doesn't require any programming and thus has to use NOP otg transceiver. Cleanups being done: - Remove unwanted code in usb-musb.c file - Register NOP in OMAP3EVM board file using usb_nop_xceiv_register(). - Select NOP_USB_XCEIV for OMAP3EVM boards. - Don't enable TWL4030_USB in omap3_evm_defconfig Signed-off-by: Ajay Kumar Gupta <ajay.gupta@ti.com> Signed-off-by: Eino-Ville Talvala <talvala@stanford.edu> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-08-07[S390] kernel: Storing machine flags early in lowcoreHendrik Brueckner
Currently, the machine_flags are stored late in the startup initialization which results in failing machine type checks (e.g. for MACHINE_IS_VM). To allow these checks, store the machine flags in the lowcore when the machine type has been detected. Moving the machine_flags to the lowcore has been introduced with git commit 25097bf153391f7be4c591d47061b3dc4990dac2 Signed-off-by: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2009-08-04x86, UV: Complete IRQ interrupt migration in arch_enable_uv_irq()Jack Steiner
In uv_setup_irq(), the call to create_irq() initially assigns IRQ vectors to cpu 0. The subsequent call to assign_irq_vector() in arch_enable_uv_irq() migrates the IRQ to another cpu and frees the cpu 0 vector - at least it will be freed as soon as the "IRQ move" completes. arch_enable_uv_irq() needs to send a cleanup IPI to complete the IRQ move. Otherwise, assignment of GRU interrupts on large systems (>200 cpus) will exhaust the cpu 0 interrupt vectors and initialization of the GRU driver will fail.

2009-08-03x86: fix assembly constraints in native_save_fl()H. Peter Anvin
From Gabe Black in bugzilla 13888: native_save_fl is implemented as follows: 11static inline unsigned long native_save_fl(void) 12{ 13 unsigned long flags; 14 15 asm volatile("# __raw_save_flags\n\t" 16 "pushf ; pop %0" 17 : "=g" (flags) 18 : /* no input */ 19 : "memory"); 20 21 return flags; 22} If gcc chooses to put flags on the stack, for instance because this is inlined into a larger function with more register pressure, the offset of the flags variable from the stack pointer will change when the pushf is performed. gcc doesn't attempt to understand that fact, and address used for pop will still be the same. It will write to somewhere near flags on the stack but not actually into it and overwrite some other value. I saw this happen in the ide_device_add_all function when running in a simulator I work on. I'm assuming that some quirk of how the simulated hardware is set up caused the code path this is on to be executed when it normally wouldn't. A simple fix might be to change "=g" to "=r".

2009-08-03x86: Add quirk to make Apple MacBook5,2 use reboot=pciPaul Mackerras
The latest Apple MacBook (MacBook5,2) doesn't reboot successfully under Linux; neither the EFI reboot method nor the default method using the keyboard controller works (the system just hangs and doesn't reset). However, the method using the "PCI reset register" at 0xcf9 does work. This adds a quirk to detect this machine via DMI and force the reboot_type to BOOT_CF9. With this it reboots successfully without requiring a command-line option. Note that the EFI code forces reboot_type to BOOT_EFI when the machine is booted via EFI, but this overrides that since the core_initcall runs after the EFI initialization code.

2009-08-03MIPS: Octeon: Run IPI code with interrupts disabled.David Daney
In mm/slab.c the function do_ccupdate_local requires that interrupts be disabled. If they are not, we panic with CONFIG_DEBUG_SLAB. So we disable interrupts while processing IPIs. Also these are not shared irqs, so get rid of the IRQF_SHARED flag. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2009-08-03MIPS: Simplify and correct interrupt handling for MSP4200Shane McDonald
The current interrupt handling code for the MSP4200 always masks an interrupt before acknowledging it. This is not required, as that will be handled by the level interrupt handler. This change simplifies the MSP4200 code to remove the masking in the ack routine, and makes sure that the minimum required operation is performed for masking and acking, rather than always both masking and acking the interrupt.

2009-08-03MIPS: MSPxxxx: define MIPS34K_MISSED_ITLB_WAR for other PMC-Sierra SoCFlorian Fainelli
Trying to build a PMC-Sierra MSP4200 VoIP gateway defconfig will not work since MIPS34K_MISSED_ITLB_WAR is not defined for all boards supported within pmc-serria/msp71xx.

2009-08-03MIPS: Fix loading of modules with unresolved weak symbolsGabor Juhos
Loading of modules with unresolved weak symbols fails on MIPS since '88173507e4fc1e7ecd111b0565e8cba0cb7dae6d'. Modules: handle symbols that have a zero value The module subsystem cannot handle symbols that are zero. If symbols are present that have a zero value then the module resolver prints out a message that these symbols are unresolved. We have to use IS_ERR_VALUE() to check that a symbol has been resolved or not. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
