2016-07-07arm64: amlogic: select gxbb clk driverMichael Turquette1-0/+2
The AmLogic clock controller code is used by both arm and arm64 architectures. Explicitly select the core code for all Meson (arm64) builds, and also select the GXBB driver, since that's the way arm64 does things.

2016-07-07arm64: kernel: Save and restore UAO and addr_limit on exception entryJames Morse4-3/+22
If we take an exception while at EL1, the exception handler inherits the original context's addr_limit and PSTATE.UAO values. To be consistent always reset addr_limit and PSTATE.UAO on (re-)entry to EL1. This prevents accidental re-use of the original context's addr_limit. Based on a similar patch for arm from Russell King.

2016-07-07locking/barriers, arch/arm64: Implement LDXR+WFE based smp_cond_load_acquire()Will Deacon2-0/+64
smp_cond_load_acquire() is used to spin on a variable until some expression involving that variable becomes true. On arm64, we can build this using the LDXR and WFE instructions, since clearing of the exclusive monitor as a result of the variable being changed by another CPU generates an event, which will wake us up out of WFE. This patch implements smp_cond_load_acquire() using LDXR and WFE, which themselves are contained in an internal __cmpwait() function.

2016-07-04arm64: dts: marvell: add peripherals clocks for Armada 37xxGregory CLEMENT1-0/+16
Add two new blocks of clocks. The peripheral clocks are the source clocks of the peripheral of the Armada 3700 SoC. Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com>
2016-07-04arm64: dts: marvell: add tbg clocks for Armada 37xxGregory CLEMENT1-0/+7
Add a new block of clocks. The Time Base Generators clocks can be the parent of the peripheral clocks. Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com>
2016-07-04arm64: dts: marvell: Add xtal clock support for Armada 3700Gregory CLEMENT1-0/+12
The configuration of the clock depend of the gpio latch. This information is stored in the gpio block registers. That's why the block is shared using a syscon node. Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com>
2016-07-04arm64: marvell: enable Armada 3700 clock driversGregory CLEMENT1-0/+1
This patch enables the support for the clocks drivers used on the Armada 3700. Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com>
2016-07-04arm/arm64: Get rid of KERN_TO_HYPMarc Zyngier1-1/+0
We have both KERN_TO_HYP and kern_hyp_va, which do the exact same thing. Let's standardize on the latter. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
2016-07-04arm/arm64: KVM: Prune unused #definesMarc Zyngier1-10/+0
We can now remove a number of dead #defines, thanks to the trampoline code being gone. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
2016-07-04arm: KVM: Allow hyp teardownMarc Zyngier1-1/+2
So far, KVM was getting in the way of kexec on 32bit (and the arm64 kexec hackers couldn't be bothered to fix it on 32bit...). With simpler page tables, tearing KVM down becomes very easy, so let's just do it. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
2016-07-04arm/arm64: KVM: Kill free_boot_hyp_pgdMarc Zyngier1-1/+0
There is no way to free the boot PGD, because it doesn't exist anymore as a standalone entity. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
2016-07-04arm/arm64: KVM: Drop boot_pgdMarc Zyngier2-5/+2
Since we now only have one set of page tables, the concept of boot_pgd is useless and can be removed. We still keep it as an element of the "extended idmap" thing. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
2016-07-04arm64: KVM: Simplify HYP init/teardownMarc Zyngier5-92/+26
Now that we only have the "merged page tables" case to deal with, there is a bunch of things we can simplify in the HYP code (both at init and teardown time). Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
2016-07-04arm/arm64: KVM: Always have merged page tablesMarc Zyngier1-24/+7
We're in a position where we can now always have "merged" page tables, where both the runtime mapping and the idmap coexist. This results in some code being removed, but there is more to come. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
2016-07-04arm64: KVM: Runtime detection of lower HYP offsetMarc Zyngier1-0/+19
Add the code that enables the switch to the lower HYP VA range. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
