[PATCH] MIPS: DEC: Restore bootmem reservation for firmware working memory area

This memory does need to be reserved on DEC platforms however as it is used by REX firmware as working area, as per the TURBOchannel firmware specification[1]: Table 2-2 REX Memory Regions ------------------------------------------------------------------------- Starting Ending Region Address Address Use ------------------------------------------------------------------------- 0 0xa0000000 0xa000ffff Restart block, exception vectors, REX stack and bss 1 0xa0010000 0xa0017fff Keyboard or tty drivers 2 0xa0018000 0xa001f3ff 1) CRT driver 3 0xa0020000 0xa002ffff boot, cnfg, init and t objects 4 0xa0020000 0xa002ffff 64KB scratch space ------------------------------------------------------------------------- 1) Note that the last 3 Kbytes of region 2 are reserved for backward compatibility with previous system software. ------------------------------------------------------------------------- (this table uses KSEG2 unmapped virtual addresses, which in the MIPS architecture are offset from physical addresses by a fixed value of 0xa0000000 and therefore the regions referred do correspond to the beginning of the physical address space) and we call into the firmware on several occasions throughout the bootstrap process. It is believed that pre-REX firmware used with non-TURBOchannel DEC platforms has the same requirements, as hinted by note #1 cited. Recreate the discarded reservation then, in DEC platform code, removing the crash.

[PATCH] arm64: dts: ipq6018: update the reserved-memory node

Memory region reserved for the TZ is changed long back. Let's update the same to align with the corret region. Its size also increased to 4MB from 2MB.

[patch 01/12] USB: sisusbvga: Make console support depend on BROKEN

by Thomas Gleixner

The console part of sisusbvga is broken vs. printk(). It uses in_atomic() to detect contexts in which it cannot sleep despite the big fat comment in preempt.h which says: Do not use in_atomic() in driver code. in_atomic() does not work on kernels with CONFIG_PREEMPT_COUNT=n which means that spin/rw_lock held regions are not detected by it. There is no way to make this work by handing context information through to the driver and this only can be solved once the core printk infrastructure supports sleepable console drivers. Make it depend on BROKEN for now.

[PATCH AUTOSEL 5.8 01/24] net: lantiq: Add locking for TX DMA channel

by Sasha Levin

From: Hauke Mehrtens <hauke(a)hauke-m.de> [ Upstream commit f9317ae5523f99999fb54c513ebabbb2bc887ddf ] The TX DMA channel data is accessed by the xrx200_start_xmit() and the xrx200_tx_housekeeping() function from different threads. Make sure the accesses are synchronized by acquiring the netif_tx_lock() in the xrx200_tx_housekeeping() function too. This lock is acquired by the kernel before calling xrx200_start_xmit().

llvm-nm and lld patches for arm32

by Nick Desaulniers

Dear Stable Maintainers, Please consider cherry-picking: commit fe00e50b2db8 ("ARM: 8858/1: vdso: use $(LD) instead of $(CC) to link VDSO") to linux-4.19.y. It cherry picks cleanly and first landed in v5.2-rc1. It allows us to more easily use ld.lld on arm32 for Android. Also, please consider cherry-picking: commit 29c623d64f0d ("ARM: 8939/1: kbuild: use correct nm executable") to both linux-5.4.y and linux-4.19.y. It cherry picks cleanly and first landed in v5.5-rc1. It allows us to more easily use llvm-nm on arm32 for Android. I've attached both backports as mbox files. Please let me know if it would be preferable in the future for me to have one email per patch being backported. I tested both locally, and the patches are passing our presubmit testing in Android. -- Thanks, ~Nick Desaulniers
