2015-06-05of/dynamic: Fix test for PPC_PSERIESGeert Uytterhoeven
"IS_ENABLED(PPC_PSERIES)" always evaluates to false, as IS_ENABLED() is supposed to be used with the full Kconfig symbol name, including the "CONFIG_" prefix. Add the missing "CONFIG_" prefix to fix this.

2015-06-04compat: cleanup coding in compat_get_bitmap() and compat_put_bitmap()Helge Deller
In the functions compat_get_bitmap() and compat_put_bitmap() the variable nr_compat_longs stores how many compat_ulong_t words should be copied in a loop. The copy loop itself is this: if (nr_compat_longs-- > 0) { if (__get_user(um, umask)) return -EFAULT; } else { um = 0; } Since nr_compat_longs gets unconditionally decremented in each loop and since it's type is unsigned this could theoretically lead to out of bounds accesses to userspace if nr_compat_longs wraps around to (unsigned)(-1). Although the callers currently do not trigger out-of-bounds accesses, we should better implement the loop in a safe way to completely avoid such warp-arounds.

2015-06-04clk: pistachio: Lock the PLL when enabled upon rate changeEzequiel Garcia
Currently, when the rate is changed, the driver makes sure the PLL is enabled before doing so. This is done because the PLL cannot be locked while disabled. Once locked, the drivers returns the PLL to its previous enable/disable state. This is a bit cumbersome, and can be simplified. This commit reworks the .set_rate() functions for the integer and fractional PLLs. Upon rate change, the PLL is now locked only if it's already enabled. Also, the driver locks the PLL on .enable(). This makes sure the PLL is locked when enabled, and not locked when disabled.

We used to read file_handle twice. Once to get the amount of extra bytes, and once to fetch the entire structure. This may be problematic since we do size verifications only after the first read, so if the number of extra bytes changes in userspace between the first and second calls, we'll have an incoherent view of file_handle. Instead, read the constant size once, and copy that over to the final structure without having to re-read it again.

2015-06-02x86/asm/irq: Stop relying on magic JMP behavior for early_idt_handlersAndy Lutomirski
The early_idt_handlers asm code generates an array of entry points spaced nine bytes apart. It's not really clear from that code or from the places that reference it what's going on, and the code only works in the first place because GAS never generates two-byte JMP instructions when jumping to global labels. Clean up the code to generate the correct array stride (member size) explicitly. This should be considerably more robust against screw-ups, as GAS will warn if a .fill directive has a negative count. Using '. =' to advance would have been even more robust (it would generate an actual error if it tried to move backwards), but it would pad with nulls, confusing anyone who tries to disassemble the code. The new scheme should be much clearer to future readers. While we're at it, improve the comments and rename the array and common code. Binutils may start relaxing jumps to non-weak labels. If so, this change will fix our build, and we may need to backport this change.

2015-06-02Revert "iommu/amd: Don't allocate with __GFP_ZERO in alloc_coherent"Joerg Roedel
This reverts commit 5fc872c7323534e8f7dc21bab635e7a9b9659e07. The DMA-API does not strictly require that the memory returned by dma_alloc_coherent is zeroed out. For that another function (dma_zalloc_coherent) should be used. But all other x86 DMA-API implementation I checked zero out the memory, so that some drivers rely on it and break when it is not. It seems the (driver-)world is not yet ready for this change, so revert it. Signed-off-by: Joerg Roedel <jroedel@suse.de>

Pull Sparc fixes from David Miller: 1) Setup the core/threads/sockets bitmaps correctly so that 'lscpus' and friends operate properly. Frtom Chris Hyser. 2) The bit that normally means "Cached Virtually" on sun4v systems, actually changes meaning in M7 and later chips. Fix from Khalid Aziz. 3) One some PCI-E systems we need to probe different OF properties to fill in the PCI slot information properly, from Eric Snowberg. 4) Kill an extraneous memset after kzalloc(), from Christophe Jaillet. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc: sparc: Resolve conflict between sparc v9 and M7 on usage of bit 9 of TTE sparc64: pci slots information is not populated in sysfs sparc: kernel: GRPCI2: Remove a useless memset sparc64: Setup sysfs to mark LDOM sockets, cores and threads correctly
