2015-01-22powerpc/ps3: Write highmem info to repositoryGeoff Levand1-2/+7

2015-01-22powerpc/ps3: Add ps3_mm_set_repository_highmemGeoff Levand1-30/+38
Add the new routine ps3_mm_set_repository_highmem() that saves highmem info to the LV1 hypervisor registry so that the info will be available to second stage OS's loaded by petitboot/kexec. FreeBSD and some Linux derivatives use this feature. Also, move the existing ps3_mm_get_repository_highmem() routine up in the source file. This implementation of ps3_mm_set_repository_highmem() assumes the repository will have a single highmem region entry (at index 0).

It looks like it's ~4 years since we updated some of these, so do a bulk update. Verified that the before and after generated configs are exactly the same. Which begs the question why update them? The answer is that it can be confusing when the stored defconfig drifts too far from the generated result. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
2014-12-29powerpc/kvm: Create proper names for the kvm_host_state PMU fieldsMichael Ellerman3-29/+40
We have two arrays in kvm_host_state that contain register values for the PMU. Currently we only create an asm-offsets symbol for the base of the arrays, and do the array offset in the assembly code. Creating an asm-offsets symbol for each field individually makes the code much nicer to read, particularly for the MMCRx/SIxR/SDAR fields, and might have helped us notice the recent double restore bug we had in this code.

2014-12-29powerpc/xmon: use isspace/isxdigit/isalnum from linux/ctype.hVincent Bernat1-12/+2
isxdigit() macro definition is the same. isalnum() from linux/ctype.h will accept additional latin non-ASCII characters. This is harmless since this macro is used in scanhex() which parses user input. isspace() from linux/ctype.h will accept vertical tab and form feed but not NULL. The use of this macro is modified to accept NULL as well. Additional characters are harmless since this macro is also only used in scanhex().

2014-12-29powerpc/pseries: relocate "config DTL" so kconfig nests properlyCody P Schafer1-10/+10
Moving config DTL up so it is below config PPC_SPLPAR means that menuconfig will show config DTL nicely indented right below config PPC_SPLPAR when PPC_SPLPAR is enabled. To contrast that, right now if I enable PPC_SPLPAR in menuconfig, all I can immediately tell is that "something showed up further down the list where I wasn't looking", and I end up having to toggle the option a few times to figure out what showed up, or look at the KConfig to find out that config DTL depends on config PPC_SPLPAR.

2014-12-26parisc: fix out-of-register compiler error in ldcw inline assembler functionJohn David Anglin1-3/+10
The __ldcw macro has a problem when its argument needs to be reloaded from memory. The output memory operand and the input register operand both need to be reloaded using a register in class R1_REGS when generating 64-bit code. This fails because there's only a single register in the class. Instead, use a memory clobber. This also makes the __ldcw macro a compiler memory barrier.

2014-12-23arm64: kernel: fix __cpu_suspend mm switch on warm-bootLorenzo Pieralisi1-1/+13
On arm64 the TTBR0_EL1 register is set to either the reserved TTBR0 page tables on boot or to the active_mm mappings belonging to user space processes, it must never be set to swapper_pg_dir page tables mappings. When a CPU is booted its active_mm is set to init_mm even though its TTBR0_EL1 points at the reserved TTBR0 page mappings. This implies that when __cpu_suspend is triggered the active_mm can point at init_mm even if the current TTBR0_EL1 register contains the reserved TTBR0_EL1 mappings. Therefore, the mm save and restore executed in __cpu_suspend might turn out to be erroneous in that, if the current->active_mm corresponds to init_mm, on resume from low power it ends up restoring in the TTBR0_EL1 the init_mm mappings that are global and can cause speculation of TLB entries which end up being propagated to user space. This patch fixes the issue by checking the active_mm pointer before restoring the TTBR0 mappings. If the current active_mm == &init_mm, the code sets the TTBR0_EL1 to the reserved TTBR0 mapping instead of switching back to the active_mm, which is the expected behaviour corresponding to the TTBR0_EL1 settings when __cpu_suspend was entered.
