2016-06-29arm: tegra: initial support for apalis tk1Apalis_TK1_LinuxImageV2.6Beta2_20160701Marcel Ziswiler
This patch adds support for the Toradex Apalis TK1 acomputer on module which can be used on different carrier boards. The module consists of a Tegra TK1 SoC, a PMIC solution, 2 GB of DDR3L RAM, a bunch of level shifters, an eMMC, a TMP451 temperature sensor chip, an I210 gigabit Ethernet controller and a SGTL5000 audio codec. Furthermore, there is a Kinetis MK20DN512 companion micro controller for analogue, CAN and resistive touch functionality which is not yet supported. This is known to boot into either a basic Angstrom/OpenEmbedded/Yocto or L4T/JetPack Ubuntu based image. The following things are known to work to a certain extend: - analogue/digital audio - debug UART1 - DVFS power management incl. low power core migration - eMMC - gigabit Ethernet - GPIOs - HDMI (incl. HDA audio) - I2C - LVDS - PCIe - SATA - SD/MMC cards - temperature sensor - USB host ports The rest is untested.

2016-06-29apalis-tk1: make hda 2nd sound card hackMarcel Ziswiler
Hack HDA driver to make it the 2nd rather than the first sound card as the first one should be the SGTL5000 which is always present on our T30 and TK1 modules. Especially on Ixora where there is no HDA codec on the carrier board HDA being the first sound card does not make much sense even more though as there was no primary device (e.g. device=hw:0,0).

2016-06-29apalis_t30/tk1: igb: no nvm and Ethernet MAC address handlingMarcel Ziswiler
Springville/i211 with a blank Flash/iNVM use different PCI IDs. Extend the driver to load despite i210/i211 data sheets claiming tools only, not for driver. Only warn rather than fail on NVM validation failures on Apalis T30. Revise Ethernet MAC address assignment: should now handle up to two instances of custom user MACs (2nd one with a 0x100000 offset). This way customer does not have to worry about NVM on a secondary Ethernet on the carrier board and still gets a valid official MAC address from us (e.g. analogous to how we did it on our Protea carrier board). Use the Toradex OUI as default MAC address if no valid one is encountered. Tested on samples of Apalis T30 2GB V1.0B, V1.0C, V1.1A, Apalis T30 1GB V1.0A, V1.1A and Apalis T30 1GB IT V1.1A both with blank NVMs as well as iNVMs programmed with Intel's defaults.

2016-06-29ARM: 8429/1: disable GCC SRA optimizationArd Biesheuvel
While working on the 32-bit ARM port of UEFI, I noticed a strange corruption in the kernel log. The following snprintf() statement (in drivers/firmware/efi/efi.c:efi_md_typeattr_format()) snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]", was producing the following output in the log: | | | | | |WB|WT|WC|UC] | | | | | |WB|WT|WC|UC] | | | | | |WB|WT|WC|UC] |RUN| | | | |WB|WT|WC|UC]* |RUN| | | | |WB|WT|WC|UC]* | | | | | |WB|WT|WC|UC] |RUN| | | | |WB|WT|WC|UC]* | | | | | |WB|WT|WC|UC] |RUN| | | | | | | |UC] |RUN| | | | | | | |UC] As it turns out, this is caused by incorrect code being emitted for the string() function in lib/vsprintf.c. The following code if (!(spec.flags & LEFT)) { while (len < spec.field_width--) { if (buf < end) *buf = ' '; ++buf; } } for (i = 0; i < len; ++i) { if (buf < end) *buf = *s; ++buf; ++s; } while (len < spec.field_width--) { if (buf < end) *buf = ' '; ++buf; } when called with len == 0, triggers an issue in the GCC SRA optimization pass (Scalar Replacement of Aggregates), which handles promotion of signed struct members incorrectly. This is a known but as yet unresolved issue. (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular case, it is causing the second while loop to be executed erroneously a single time, causing the additional space characters to be printed. So disable the optimization by passing -fno-ipa-sra.

2016-06-29ARM: 8158/1: LLVMLinux: use static inline in ARM ftrace.hBehan Webster
With compilers which follow the C99 standard (like modern versions of gcc and clang), "extern inline" does the wrong thing (emits code for an externally linkable version of the inline function). In this case using static inline and removing the NULL version of return_address in return_address.c does the right thing.

2016-05-24video: tegra: host: Fix ch open error handlingArto Merilainen
In case kernel fails to open a channel (e.g. due to inability to allocate hardware context or turn on the device), the channel open function releases the resources that were already allocated successfully. However, currently the error path additionally calls the channel release function for putting the channel pointer after the private data structures have been freed - thereby causing use-after-free memory usage. This patch reworks error handling in channel open to release channel without risking usage of already freed memory.

2016-03-29pipe: iovec: Fix memory corruption when retrying atomic copy as non-atomicBen Hutchings
pipe_iov_copy_{from,to}_user() may be tried twice with the same iovec, the first time atomically and the second time not. The second attempt needs to continue from the iovec position, pipe buffer offset and remaining length where the first attempt failed, but currently the pipe buffer offset and remaining length are reset. This will corrupt the piped data (possibly also leading to an information leak between processes) and may also corrupt kernel memory. This was fixed upstream by commits f0d1bec9d58d ("new helper: copy_page_from_iter()") and 637b58c2887e ("switch pipe_read() to copy_page_to_iter()"), but those aren't suitable for stable. This fix for older kernel versions was made by Seth Jennings for RHEL and I have extracted it from their update.
