The Qualcomm SCM driver was never explicitly enabled in the defconfig.
Instead it was (apparently) selected by DRM_MSM and by the recent change
to make it tristate now became =m.
Unfortunately this removes the ability for PINCTRL_MSM and ARM_SMMU to
be =y and with deferred_probe_timeout defaulting to 0 this means that
things such as UART, USB, PCIe and SDHCI probes with their dependencies
ignored.
The lack of pinctrl results in invalid pin configuration and the lack of
iommu results in the system locking up as soon as any form of data
transfer is attempted from any of the affected peripherals.
Mark QCOM_SCM as builtin, to avoid this.

Further there was only one user ever.
- Android's loadfont, busybox and console-tools only ever use OP_GET
and OP_SET
- fbset documentation only mentions the kernel cmdline font: option,
not anything else.
- systemd used OP_COPY before release 232 published in Nov 2016
Now unfortunately the crucial report seems to have gone down with
gmane, and the commit message doesn't say much. But the pull request
hints at OP_COPY being broken
https://github.com/systemd/systemd/pull/3651
So in other words, this never worked, and the only project which
foolishly every tried to use it, realized that rather quickly too.
Instead of trying to fix security issues here on dead code by adding
missing checks, fix the entire thing by removing the functionality.
Note that systemd code using the OP_COPY function ignored the return
value, so it doesn't matter what we're doing here really - just in
case a lone server somewhere happens to be extremely unlucky and
running an affected old version of systemd. The relevant code from
font_copy_to_all_vcs() in systemd was:
/* copy font from active VT, where the font was uploaded to */
cfo.op = KD_FONT_OP_COPY;
cfo.height = vcs.v_active-1; /* tty1 == index 0 */
(void) ioctl(vcfd, KDFONTOP, &cfo);
Note this just disables the ioctl, garbage collecting the now unused
callbacks is left for -next.
v2: Tetsuo found the old mail, which allowed me to find it on another
archive. Add the link too.

Merge procfs splice read fixes from Christoph Hellwig:
"Greg reported a problem due to the fact that Android tests use procfs
files to test splice, which stopped working with the changes for
set_fs() removal.
This series adds read_iter support for seq_file, and uses those for
various proc files using seq_file to restore splice read support"
[ Side note: Christoph initially had a scripted "move everything over"
patch, which looks fine, but I personally would prefer us to actively
discourage splice() on random files. So this does just the minimal
basic core set of proc file op conversions.
For completeness, and in case people care, that script was
sed -i -e 's/\.proc_read\(\s*=\s*\)seq_read/\.proc_read_iter\1seq_read_iter/g'
but I'll wait and see if somebody has a strong argument for using
splice on random small /proc files before I'd run it on the whole
kernel. - Linus ]
* emailed patches from Christoph Hellwig <hch@lst.de>:
proc "seq files": switch to ->read_iter
proc "single files": switch to ->read_iter

- Fix the fallout of the IPI as interrupt conversion in Kconfig and
the BCM2836 interrupt chip driver
- Fixes for interrupt affinity setting and the handling of
hierarchical irq domains in the SiFive PLIC driver
- Make the unmapped event handling in the TI SCI driver work
correctly
- A few minor fixes and cleanups in various chip drivers and Kconfig"

the RCU check.
