* scripts: add "prune-kernel" script to clean up old kernel imagesJ. Bruce Fields2016-02-091-0/+20
| | | | | | | | | | | | | | | | | | | | | | | Long ago, Dave Jones complained about CONFIG_LOCALVERSION_AUTO: "I don't use the auto config, because I end up filling up /boot unless I go through and clean them out by hand every time I install a new one (which I do probably a dozen or so times a day). Is there some easy way to prune old builds I'm missing?" To which Bruce replied: "I run this by hand every now and then. I'm probably doing it all wrong" And if he is running it wrong, then so am I - because I've been using this script ever since. It is true that CONFIG_LOCALVERSION_AUTO easily ends up filling your /boot partition if you don't clean up old versions regularly, and this script helps make that easier. Checked with Bruce to see that it's fine to add this to the kernel scripts. Maybe people will come up with enhancements, but more importantly, this way I won't misplace this script whenever I install a new machine and start doing custom kernels for it.

| | * arm64: KVM: Obey RES0/1 reserved bits when setting CPTR_EL2Dave Martin2016-01-242-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some bits in CPTR are defined as RES1 in the architecture. Setting these bits to zero may unintentionally enable future architecture extensions, allowing guests to use them without supervision by the host. This would be bad: for forwards compatibility, this patch makes sure the affected bits are always written with 1, not 0. This patch only addresses CPTR_EL2. Initialisation of other system registers may still need review.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment, our fault injection is pretty limited. We always generate a SYNC exception into EL1, as if the fault was actually from EL1h, no matter how it was generated. This is obviously wrong, as EL0 can generate faults of its own (not to mention the pretty-much unused EL1t mode). This patch fixes it by implementing section D1.10.2 of the ARMv8 ARM, and in particular table D1-7 ("Vector offsets from vector table base address"), which describes which vector to use depending on the source exception level and type (synchronous, IRQ, FIQ or SError).

MIPS systems had worked around this by declaring regmap using IPs as little endian which is inaccurate, unfortunately the issue had not been reported. Sadly the fix makes things worse rather than better. By changing the behaviour to match the documentation it caused behaviour changes for other IPs which broke them and by using the __raw I/O accessors to avoid the endianness swapping in readl()/writel() it removed some memory ordering guarantees and could potentially generate unvirtualisable instructions on some architectures. Unfortunately sorting out all this mess in any half way sensible fashion was far too invasive to go in during an -rc cycle so instead let's go back to the old broken behaviour for v4.5, the better fixes are already queued for v4.6. This does mean that we keep the broken MIPS DTs for another release but that seems the least bad way of handling the situation.

Quite a bit of the changes on OMAP were due to fixes to no longer write to rodata from assembly when ARM_KERNMEM_PERMS was enabled, but there were also other fixes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DTSI file for the Nomadik does not properly specify how the PL180 levelshifter is connected: the Nomadik actually needs all the five st,sig-dir-* flags set to properly control all lines out. Further this board supports full power cycling of the card, and since this variant has no hardware clock gating, it needs a ridiculously low frequency setting to keep up with the ever overflowing FIFO. The pin configuration set-up is a bit of a mystery, because of course these pins are a mix of inputs and outputs. However the reference implementation sets all pins to "output" with unspecified initial value, so let's do that here as well.

We had several places writing to rodata, which is bad. The fix in most cases is to load the value from data section using a pointer. Let's also enable ARM_KERNMEM_PERMS so DEBUG_RODATA gets selected by default. And while testing things, I also added few more loadable driver modules to the defconfig that I seem to need quite often. - Fix a long standing omap5 RTC mystery and enable RTC where we need to ensure the SoC msecure pin is high so we can write to the RTC registers. - Fix irq types for am437x - A series of minor dts fixes for sbc-am57x and cl-som-am57x - Fixes for torpedo dts to make WLAN behave and to remove a duplicate i2c rate entry This series also includes few minor changes that are not stricly fixes, but would be good to get in during the early -rc cycle: - Remove legacy mailbox platform data that is no longer needed - Add the pdata-quirks needed for the new pwm-omap-dmtimer so people can use it - Enable ti,mbox-send-noirq that's needed by wkup_m3 driver - Enable SPLIT and DWARF4 in omap2plus_defconfig as it makes the initramfs quite a bit smaller * tag 'omap-for-v4.5/fixes-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (23 commits) ARM: dts: am57xx: sbc-am57x: correct Eth PHY settings ARM: dts: am57xx: cl-som-am57x: fix CPSW EMAC pinmux ARM: dts: am57xx: sbc-am57x: fix UART3 pinmux ARM: dts: am57xx: cl-som-am57x: update SPI Flash frequency ARM: dts: am57xx: cl-som-am57x: set HOST mode for USB2 ARM: dts: am57xx: sbc-am57x: fix SB-SOM EEPROM I2C address ARM: dts: LogicPD Torpedo: Revert Duplicative Entries ARM: dts: am437x: pixcir_tangoc: use correct flags for irq types ARM: dts: am4372: fix irq type for arm twd and global timer ARM: dts: Fix wl12xx missing clocks that cause hangs ARM: OMAP: Add PWM dmtimer platform data quirks ARM: omap2plus_defconfig: Enable ARM_KERNMEM_PERMS and few loadable modules ARM: OMAP2+: Fix ppa_zero_params and ppa_por_params for rodata ARM: OMAP2+: Fix l2_inv_api_params for rodata ARM: OMAP2+: Fix save_secure_ram_context for rodata ARM: OMAP2+: Fix l2dis_3630 for rodata ARM: OMAP2+: Fix wait_dll_lock_timed for rodata ARM: OMAP2+: Remove legacy mailbox device instantiation ARM: dts: AM4372: Add ti,mbox-send-noirq to wkup_m3 mailbox ARM: dts: AM33xx: Add ti,mbox-send-noirq to wkup_m3 mailbox ...
