2019-09-21ARM: 8901/1: add a criteria for pfn_valid of armzhaoyang1-0/+5
[ Upstream commit 5b3efa4f1479c91cb8361acef55f9c6662feba57 ] pfn_valid can be wrong when parsing a invalid pfn whose phys address exceeds BITS_PER_LONG as the MSB will be trimed when shifted. The issue originally arise from bellowing call stack, which corresponding to an access of the /proc/kpageflags from userspace with a invalid pfn parameter and leads to kernel panic.

2019-09-21ARM: 8874/1: mm: only adjust sections of valid mm structuresDoug Berger1-1/+2
[ Upstream commit c51bc12d06b3a5494fbfcbd788a8e307932a06e9 ] A timing hazard exists when an early fork/exec thread begins exiting and sets its mm pointer to NULL while a separate core tries to update the section information. This commit ensures that the mm pointer is not NULL before setting its section parameters. The arguments provided by commit 11ce4b33aedc ("ARM: 8672/1: mm: remove tasklist locking from update_sections_early()") are equally valid for not requiring grabbing the task_lock around this check.

2019-09-21ARM: dts: Fix incomplete dts data for am3 and am4 mmcTony Lindgren2-12/+52
[ Upstream commit 5b63fb90adb95a178ad403e1703f59bf1ff2c16b ] Commit 4e27f752ab8c ("ARM: OMAP2+: Drop mmc platform data for am330x and am43xx") dropped legacy mmc platform data for am3 and am4, but missed the fact that we never updated the dts files for mmc3 that is directly on l3 interconnect instead of l4 interconnect. This leads to a situation with no legacy platform data and incomplete dts data. Let's update the mmc instances on l3 interconnect to probe properly with ti-sysc interconnect target module driver to make mmc3 work again. Let's still keep legacy "ti,hwmods" property around for v5.2 kernel and only drop it later on. Note that there is no need to use property status = "disabled" for mmc3. The default for dts is enabled, and runtime PM will idle unused instances just fine.

2019-09-21ARM: dts: am57xx: Disable voltage switching for SD cardFaiz Abbas6-30/+6
[ Upstream commit fb59ee37cfe20d10d19568899d1458a58361246c ] If UHS speed modes are enabled, a compatible SD card switches down to 1.8V during enumeration. If after this a software reboot/crash takes place and on-chip ROM tries to enumerate the SD card, the difference in IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card. The fix for this is to have support for power cycling the card in hardware (with a PORz/soft-reset line causing a power cycle of the card). Because the beaglebone X15 (rev A,B and C), am57xx-idks and am57xx-evms don't have this capability, disable voltage switching for these boards. The major effect of this is that the maximum supported speed mode is now high speed(50 MHz) down from SDR104(200 MHz). commit 88a748419b84 ("ARM: dts: am57xx-idk: Remove support for voltage switching for SD card") did this only for idk boards.

2019-08-29KVM: arm: Don't write junk to CP15 registers on resetMarc Zyngier1-8/+15
[ Upstream commit c69509c70aa45a8c4954c88c629a64acf4ee4a36 ] At the moment, the way we reset CP15 registers is mildly insane: We write junk to them, call the reset functions, and then check that we have something else in them. The "fun" thing is that this can happen while the guest is running (PSCI, for example). If anything in KVM has to evaluate the state of a CP15 register while junk is in there, bad thing may happen. Let's stop doing that. Instead, we track that we have called a reset function for that register, and assume that the reset function has done something. In the end, the very need of this reset check is pretty dubious, as it doesn't check everything (a lot of the CP15 reg leave outside of the cp15_regs[] array). It may well be axed in the near future.

2019-08-06ARM: dts: rockchip: Mark that the rk3288 timer might stop in suspendDouglas Anderson1-0/+1
[ Upstream commit 8ef1ba39a9fa53d2205e633bc9b21840a275908e ] This is similar to commit e6186820a745 ("arm64: dts: rockchip: Arch counter doesn't tick in system suspend"). Specifically on the rk3288 it can be seen that the timer stops ticking in suspend if we end up running through the "osc_disable" path in rk3288_slp_mode_set(). In that path the 24 MHz clock will turn off and the timer stops. To test this, I ran this on a Chrome OS filesystem: before=$(date); \ suspend_stress_test -c1 --suspend_min=30 --suspend_max=31; \ echo ${before}; date ...and I found that unless I plug in a device that requests USB wakeup to be active that the two calls to "date" would show that fewer than 30 seconds passed. NOTE: deep suspend (where the 24 MHz clock gets disabled) isn't supported yet on upstream Linux so this was tested on a downstream kernel.

The commit fe00e50b2db8 ("ARM: 8858/1: vdso: use $(LD) instead of $(CC) to link VDSO") removed the passing of CFLAGS, since ld doesn't take those directly. However, prior, big-endian ARM was relying on gcc to translate its -mbe8 option into ld's --be8 option. Lacking this, ld generated be32 code, making the VDSO generate SIGILL when called by userspace. This commit passes --be8 if CONFIG_CPU_ENDIAN_BE8 is enabled. Signed-off-by: Jason A.

This is often because omap3xxx_prm_late_init lacks a __init annotation or the annotation of omap3xxx_prm_enable_io_wakeup is wrong.
