2013-04-29ARM: tegra: call cpu_do_idle from C codeArnd Bergmann2-1/+6
When building a kernel for multiple CPU architecture levels, cpu_do_idle() is a macro for an indirect function call, which cannot be called from assembly code as Tegra does. Adding a trivial C wrapper for this function lets us build a tegra kernel with ARMv6 support enabled.

2013-04-23ARM: OMAP2+: add dependencies on ARCH_MULTI_V6/V7Arnd Bergmann1-0/+5
CONFIG_ARCH_OMAP2PLUS depends on (ARCH_MULTI_V6 || ARCH_MULTI_V7) as of a0694861 "ARM: OMAP2+: Enable ARCH_MULTIPLATFORM support", but the individual OMAP2/3/4/5 and AM33XX platforms can all be selected independent of what we are building for, which is a bug and prevents us from easily building e.g. an ARMv7-only defconfig. This makes ARCH_OMAP2 depend on ARCH_MULTI_V6 and the others depend on ARCH_MULTI_V7, to ensure we really only build the platforms for the CPUs we have enabled in the global multiplatform configuration step.

2013-04-11ARM: msm: Fix uncompess.h tx underrun checkStephen Boyd1-1/+1
Bit 3 of the SR register is set if there is a tx underrun. If this bit isn't set, we should loop on the tx ready bit until we can transmit again. Otherwise we should skip the loop and transmit immediately. The code is doing the opposite though, checking for an underrun and then looping on the tx ready bit causing us to never loop on the tx read bit when the tx buffer may not be ready. This doesn't seem to affect my 8960 device too often, but in some cases I see a lost character or two from the decompressor prints. This also matches what we do in the assembly in debug-macro.S.

2013-03-31ARM: OMAP: dpll: enable bypass clock only when attempting dpll bypassRajendra Nayak1-10/+9
omap3_noncore_dpll_set_rate() attempts an enable of bypass clk as well as ref clk for every .set_rate attempt on a noncore DPLL, regardless of whether the .set_rate results in the DPLL being locked or put in bypass. Early at boot, while some of these DPLLs are programmed and locked (using .set_rate for the DPLL), this causes an ordering issue. For instance, on OMAP5, the USB DPLL derives its bypass clk from ABE DPLL. If a .set_rate of USB DPLL which programmes the M,N and locks it is called before the one for ABE, the enable of USB bypass clk (derived from ABE DPLL) then attempts to lock the ABE DPLL and fails as the M,N values for ABE are yet to be programmed. To get rid of this ordering needs, enable bypass clk for a DPLL as part of its .set_rate only when its being put in bypass, and only enable the ref clk when its locked.

WDT1 module can take one of the below clocks as input functional clock - - On-Chip 32K RC Osc [default/reset] - 32K from PRCM The On-Chip 32K RC Osc clock is not an accurate clock-source as per the design/spec, so as a result, for example, timer which supposed to get expired @60Sec, but will expire somewhere ~@40Sec, which is not expected by any use-case. The solution here is to switch the input clock-source to PRCM generated 32K clock-source during boot-time itself.

git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc Pull arc architecture fixes from Vineet Gupta: "This includes fix for a serious bug in DMA mapping API, make allyesconfig wreckage, removal of bogus email-list placeholder in MAINTAINERS, a typo in ptrace helper code and last remaining changes for syscall ABI v3 which we are finally starting to transition-to internally. The request is late than I intended to - but I was held up with debugging a timer link list corruption, for which a proposed fix to generic timer code was sent out to lkml/tglx earlier today." * 'for-curr' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc: ARC: Fix the typo in event identifier flags used by ptrace arc: fix dma_address assignment during dma_map_sg() ARC: Remove SET_PERSONALITY (tracks cross-arch change) ARC: ABIv3: fork/vfork wrappers not needed in "no-legacy-syscall" ABI ARC: ABIv3: Print the correct ABI ver ARC: make allyesconfig build breakages ARC: MAINTAINERS update for ARC
2013-03-29ARM: tegra: powergate: Don't error out if new state == old stateThierry Reding1-1/+1
Don't treat it as an error if a partition is already in the same power state when a user wants to power it on or off. This allows code to proceed if no state change is required. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Stephen Warren <swarren@nvidia.com>
2013-03-29ARM: tegra: Export tegra_powergate_sequence_power_up()Thierry Reding1-0/+2
This function can be used by drivers to enable power to the hardware blocks that they drive. Most of the drivers can be built as a module and therefore require this function to be exported.

There are also two bug-fixes: one that adds an extra layer of security, and a regression fix for a change that was added in v3.7 (the v1 was faulty, the v2 works). - Regression fixes for C-and-P states not being parsed properly. - Fix possible security issue with guests triggering DoS via non-assigned MSI-Xs. - Fix regression (introduced in v3.7) with raising an event (v2). - Fix hastily introduced band-aid during c0 for the CR3 blowup." * tag 'stable/for-linus-3.9-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen/events: avoid race with raising an event in unmask_evtchn() xen/mmu: Move the setting of pvops.write_cr3 to later phase in bootup. xen/acpi-stub: Disable it b/c the acpi_processor_add is no longer called. xen-pciback: notify hypervisor about devices intended to be assigned to guests xen/acpi-processor: Don't dereference struct acpi_processor on all CPUs.
2013-03-27xen/mmu: Move the setting of pvops.write_cr3 to later phase in bootup.Konrad Rzeszutek Wilk1-2/+1
We move the setting of write_cr3 from the early bootup variant (see git commit 0cc9129d75ef8993702d97ab0e49542c15ac6ab9 "x86-64, xen, mmu: Provide an early version of write_cr3.") to a more appropiate location. This new location sets all of the other non-early variants of pvops calls - and most importantly is before the alternative_asm mechanism kicks in.

2013-03-26powerpc: define the conditions where the ePAPR idle hcall can be supportedStuart Yoder1-0/+6
For 32-bit, CONFIG_EPAPR_PARAVIRT pulls in both epapr_paravirt.c and epapr_hcalls.c which contains the 32-bit paravirt idle loop. For 64-bit, the paravirt idle loop is in idle_book3e.S and that source file is included only if CONFIG_PPC_BOOK3E_64 defined. This patch makes that dependency for 64-bit explicit. Fixes these build errors: arch/powerpc/kernel/built-in.o: In function `restore_pblist_ptr': ftrace.c:(.toc+0xdc0): undefined reference to `epapr_ev_idle_start' ftrace.c:(.toc+0xdd0): undefined reference to `epapr_ev_idle' Signed-off-by: Stuart Yoder <stuart.yoder@freescale.com> Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
