kbuild: introduce ccflags-remove-y and asflags-remove-y
CFLAGS_REMOVE_<file>.o filters out flags when compiling a particular
object, but there is no convenient way to do that for every object in
a directory.
Add ccflags-remove-y and asflags-remove-y to make it easily.
Use ccflags-remove-y to clean up some Makefiles.
The add/remove order works as follows:
[1] KBUILD_CFLAGS specifies compiler flags used globally
[2] ccflags-y adds compiler flags for all objects in the
current Makefile
[3] ccflags-remove-y removes compiler flags for all objects in the
current Makefile (New feature)
[4] CFLAGS_<file> adds compiler flags per file.
[5] CFLAGS_REMOVE_<file> removes compiler flags per file.
Having [3] before [4] allows us to remove flags from most (but not all)
objects in the current Makefile.
For example, kernel/trace/Makefile removes $(CC_FLAGS_FTRACE)
from all objects in the directory, then adds it back to
trace_selftest_dynamic.o and CFLAGS_trace_kprobe_selftest.o
The same applies to lib/livepatch/Makefile.
Please note ccflags-remove-y has no effect to the sub-directories.
In contrast, the previous notation got rid of compiler flags also from
all the sub-directories.
The following are not affected because they have no sub-directories:
arch/arm/boot/compressed/
arch/powerpc/xmon/
arch/sh/
kernel/trace/
However, lib/ has several sub-directories.
To keep the behavior, I added ccflags-remove-y to all Makefiles
in subdirectories of lib/, except the following:
lib/vdso/Makefile - Kbuild does not descend into this Makefile
lib/raid/test/Makefile - This is not used for the kernel build
I think commit

kbuild: do not export LDFLAGS_vmlinux
When you clean the build tree for ARCH=arm, you may see the following error message from 'nm' command: $ make -j24 ARCH=arm clean CLEAN arch/arm/crypto CLEAN arch/arm/kernel CLEAN arch/arm/mach-at91 CLEAN arch/arm/mach-omap2 CLEAN arch/arm/vdso CLEAN certs CLEAN lib CLEAN usr CLEAN net/wireless CLEAN drivers/firmware/efi/libstub nm: 'arch/arm/boot/compressed/../../../../vmlinux': No such file /bin/sh: 1: arithmetic expression: expecting primary: " " CLEAN arch/arm/boot/compressed CLEAN drivers/scsi CLEAN drivers/tty/vt CLEAN arch/arm/boot CLEAN vmlinux.symvers modules.builtin modules.builtin.modinfo Even if you rerun the same command, the error message will not be shown despite vmlinux is already gone. To reproduce it, the parallel option -j is needed. Single thread cleaning always executes 'archclean', 'vmlinuxclean' in this order, so vmlinux still exists when arch/arm/boot/compressed/ is cleaned. Looking at arch/arm/boot/compressed/Makefile does not help understand the reason of the error message. Both KBSS_SZ and LDFLAGS_vmlinux are assigned with '=' operator, hence, they are not expanded unless used. Obviously, 'make clean' does not use them. In fact, the root cause exists in the top Makefile: export LDFLAGS_vmlinux Since LDFLAGS_vmlinux is an exported variable, LDFLAGS_vmlinux in arch/arm/boot/compressed/Makefile is expanded when scripts/Makefile.clean has a command to execute. This is why the error message shows up only when there exist build artifacts in arch/arm/boot/compressed/. Adding 'unexport LDFLAGS_vmlinux' to arch/arm/boot/compressed/Makefile will fix it as far as ARCH=arm is concerned, but I think the proper fix is to get rid of 'export LDFLAGS_vmlinux' from the top Makefile. LDFLAGS_vmlinux in the top Makefile contains linker flags for the top vmlinux. LDFLAGS_vmlinux in arch/arm/boot/compressed/Makefile is for arch/arm/boot/compressed/vmlinux. They just happen to have the same variable name, but are used for different purposes. Stop shadowing LDFLAGS_vmlinux. This commit passes LDFLAGS_vmlinux to scripts/link-vmlinux.sh via a command line parameter instead of via an environment variable. LD and KBUILD_LDFLAGS are exported, but I did the same for consistency. Anyway, they must be included in cmd_link-vmlinux to allow if_changed to detect the changes in LD or KBUILD_LDFLAGS. The following Makefiles are not affected: arch/arm/boot/compressed/Makefile arch/h8300/boot/compressed/Makefile arch/nios2/boot/compressed/Makefile arch/parisc/boot/compressed/Makefile arch/s390/boot/compressed/Makefile arch/sh/boot/compressed/Makefile arch/sh/boot/romimage/Makefile arch/x86/boot/compressed/Makefile They use ':=' or '=' to clear the LDFLAGS_vmlinux inherited from the top Makefile. We need to take a closer look at the impact to unicore32 and xtensa. arch/unicore32/boot/compressed/Makefile only uses '+=' operator for LDFLAGS_vmlinux. So, the decompressor previously inherited the linker flags from the top Makefile. However, commit |

powerpc/boot: add DTB to 'targets'
PowerPC always re-builds DTB even if nothing has been changed. As for other architectures, arch/*/boot/dts/Makefile builds DTB by using the dtb-y syntax. In contrast, arch/powerpc/boot/dts/(fsl/)Makefile does nothing unless CONFIG_OF_ALL_DTBS is defined. Instead, arch/powerpc/boot/Makefile builds DTB on demand. You need to add DTB to 'targets' explicitly so .*.cmd files are included. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Acked-by: Michael Ellerman <mpe@ellerman.id.au> |

kbuild: remove cc-option test of -ffreestanding
Some Makefiles already pass -ffreestanding unconditionally. For example, arch/arm64/lib/Makefile, arch/x86/purgatory/Makefile. No problem report so far about hard-coding this option.

x86/ldt: use "pr_info_once()" instead of open-coding it badly
Using a mutex for "print this warning only once" is so overdesigned as to be actively offensive to my sensitive stomach. Just use "pr_info_once()" that already does this, although in a (harmlessly) racy manner that can in theory cause the message to be printed twice if more than one CPU races on that "is this the first time" test. [ If somebody really cares about that harmless data race (which sounds very unlikely indeed), that person can trivially fix printk_once() by using a simple atomic access, preferably with an optimistic non-atomic test first before even bothering to treat the pointless "make sure it is _really_ just once" case. A mutex is most definitely never the right primitive to use for something like this. ] Yes, this is a small and meaningless detail in a code path that hardly matters. But let's keep some code quality standards here, and not accept outrageously bad code.

A series of fixes for x86:
- Reset MXCSR in kernel_fpu_begin() to prevent using a stale user space
value.
- Prevent writing MSR_TEST_CTRL on CPUs which are not explicitly
whitelisted for split lock detection. Some CPUs which do not support
it crash even when the MSR is written to 0 which is the default value.
- Fix the XEN PV fallout of the entry code rework
- Fix the 32bit fallout of the entry code rework
- Add more selftests to ensure that these entry problems don't come back.
- Disable 16 bit segments on XEN PV. It's not supported because XEN PV
does not implement ESPFIX64

MIPS: Add missing EHB in mtc0 -> mfc0 sequence for DSPen
This resolves the hazard between the mtc0 in the change_c0_status() and the mfc0 in configure_exception_vector(). Without resolving this hazard configure_exception_vector() could read an old value and would restore this old value again. This would revert the changes change_c0_status() did. I checked this by printing out the read_c0_status() at the end of per_cpu_trap_init() and the ST0_MX is not set without this patch. The hazard is documented in the MIPS Architecture Reference Manual Vol. III: MIPS32/microMIPS32 Privileged Resource Architecture (MD00088), rev 6.03 table 8.1 which includes: Producer | Consumer | Hazard ----------|----------|---------------------------- mtc0 | mfc0 | any coprocessor 0 register I saw this hazard on an Atheros AR9344 rev 2 SoC with a MIPS 74Kc CPU. There the change_c0_status() function would activate the DSPen by setting ST0_MX in the c0_status register. This was reverted and then the system got a DSP exception when the DSP registers were saved in save_dsp() in the first process switch. The crash looks like this: [ 0.089999] Mount-cache hash table entries: 1024 (order: 0, 4096 bytes, linear) [ 0.097796] Mountpoint-cache hash table entries: 1024 (order: 0, 4096 bytes, linear) [ 0.107070] Kernel panic - not syncing: Unexpected DSP exception [ 0.113470] Rebooting in 1 seconds.. We saw this problem in OpenWrt only on the MIPS 74Kc based Atheros SoCs, not on the 24Kc based SoCs. We only saw it with kernel 5.4 not with kernel 4.19, in addition we had to use GCC 8.4 or 9.X, with GCC 8.3 it did not happen. In the kernel I bisected this problem to commit |

x86/ldt: Disable 16-bit segments on Xen PV
Xen PV doesn't implement ESPFIX64, so they don't work right. Disable them. Also print a warning the first time anyone tries to use a 16-bit segment on a Xen PV guest that would otherwise allow it to help people diagnose this change in behavior.

x86/entry/32: Fix #MC and #DB wiring on x86_32
DEFINE_IDTENTRY_MCE and DEFINE_IDTENTRY_DEBUG were wired up as non-RAW on x86_32, but the code expected them to be RAW. Get rid of all the macro indirection for them on 32-bit and just use DECLARE_IDTENTRY_RAW and DEFINE_IDTENTRY_RAW directly. Also add a warning to make sure that we only hit the _kernel paths in kernel mode.

x86/entry/xen: Route #DB correctly on Xen PV
On Xen PV, #DB doesn't use IST. It still needs to be correctly routed
depending on whether it came from user or kernel mode.
Get rid of DECLARE/DEFINE_IDTENTRY_XEN -- it was too hard to follow the
logic. Instead, route #DB and NMI through DECLARE/DEFINE_IDTENTRY_RAW on
Xen, and do the right thing for #DB. Also add more warnings to the
exc_debug* handlers to make this type of failure more obvious.
This fixes various forms of corruption that happen when usermode
triggers #DB on Xen PV.

arm64/alternatives: use subsections for replacement sequences
When building very large kernels, the logic that emits replacement sequences for alternatives fails when relative branches are present in the code that is emitted into the .altinstr_replacement section and patched in at the original site and fixed up. The reason is that the linker will insert veneers if relative branches go out of range, and due to the relative distance of the .altinstr_replacement from the .text section where its branch targets usually live, veneers may be emitted at the end of the .altinstr_replacement section, with the relative branches in the sequence pointed at the veneers instead of the actual target. The alternatives patching logic will attempt to fix up the branch to point to its original target, which will be the veneer in this case, but given that the patch site is likely to be far away as well, it will be out of range and so patching will fail. There are other cases where these veneers are problematic, e.g., when the target of the branch is in .text while the patch site is in .init.text, in which case putting the replacement sequence inside .text may not help either. So let's use subsections to emit the replacement code as closely as possible to the patch site, to ensure that veneers are only likely to be emitted if they are required at the patch site as well, in which case they will be in range for the replacement sequence both before and after it is transported to the patch site. This will prevent alternative sequences in non-init code from being released from memory after boot, but this is tolerable given that the entire section is only 512 KB on an allyesconfig build (which weighs in at 500+ MB for the entire Image). Also, note that modules today carry the replacement sequences in non-init sections as well, and any of those that target init code will be emitted into init sections after this change. This fixes an early crash when booting an allyesconfig kernel on a system where any of the alternatives sequences containing relative branches are activated at boot (e.g., ARM64_HAS_PAN on TX2) Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Cc: Suzuki K Poulose <suzuki.poulose@arm.com> Cc: James Morse <james.morse@arm.com> Cc: Andre Przywara <andre.przywara@arm.com> Cc: Dave P Martin <dave.martin@arm.com> Link: https://lore.kernel.org/r/20200630081921.13443-1-ardb@kernel.org Signed-off-by: Will Deacon <will@kernel.org> |

x86/entry/64/compat: Fix Xen PV SYSENTER frame setup
The SYSENTER frame setup was nonsense. It worked by accident because the
normal code into which the Xen asm jumped (entry_SYSENTER_32/compat) threw
away SP without touching the stack. entry_SYSENTER_compat was recently
modified such that it relied on having a valid stack pointer, so now the
Xen asm needs to invoke it with a valid stack.
Fix it up like SYSCALL: use the Xen-provided frame and skip the bare
metal prologue.

x86/split_lock: Don't write MSR_TEST_CTRL on CPUs that aren't whitelisted
Choo! Choo! All aboard the Split Lock Express, with direct service to
Wreckage!
Skip split_lock_verify_msr() if the CPU isn't whitelisted as a possible
SLD-enabled CPU model to avoid writing MSR_TEST_CTRL. MSR_TEST_CTRL
exists, and is writable, on many generations of CPUs. Writing the MSR,
even with '0', can result in bizarre, undocumented behavior.
This fixes a crash on Haswell when resuming from suspend with a live KVM
guest. Because APs use the standard SMP boot flow for resume, they will
go through split_lock_init() and the subsequent RDMSR/WRMSR sequence,
which runs even when sld_state==sld_off to ensure SLD is disabled. On
Haswell (at least, my Haswell), writing MSR_TEST_CTRL with '0' will
succeed and _may_ take the SMT _sibling_ out of VMX root mode.
When KVM has an active guest, KVM performs VMXON as part of CPU onlining
(see kvm_starting_cpu()). Because SMP boot is serialized, the resulting
flow is effectively:
on_each_ap_cpu() {
WRMSR(MSR_TEST_CTRL, 0)
VMXON
}
As a result, the WRMSR can disable VMX on a different CPU that has
already done VMXON. This ultimately results in a #UD on VMPTRLD when
KVM regains control and attempt run its vCPUs.
The above voodoo was confirmed by reworking KVM's VMXON flow to write
MSR_TEST_CTRL prior to VMXON, and to serialize the sequence as above.
Further verification of the insanity was done by redoing VMXON on all
APs after the initial WRMSR->VMXON sequence. The additional VMXON,
which should VM-Fail, occasionally succeeded, and also eliminated the
unexpected #UD on VMPTRLD.
The damage done by writing MSR_TEST_CTRL doesn't appear to be limited
to VMX, e.g. after suspend with an active KVM guest, subsequent reboots
almost always hang (even when fudging VMXON), a #UD on a random Jcc was
observed, suspend/resume stability is qualitatively poor, and so on and
so forth.

ARM: OMAP fixes for v5.8
The OMAP developers are particularly active at hunting down regressions,
so this is a separate branch with OMAP specific fixes for the v5.8:
As Tony explains
"The recent display subsystem (DSS) related platform data changes
caused display related regressions for suspend and resume. Looks like
I only tested suspend and resume before dropping the legacy platform
data, and forgot to test it after dropping it. Turns out the main issue
was that we no longer have platform code calling pm_runtime_suspend
for DSS like we did for the legacy platform data case, and that fix
is still being discussed on the dri-devel list and will get merged
separately. The DSS related testing exposed a pile other other display
related issues that also need fixing though":
- Fix ti-sysc optional clock handling and reset status checks
for devices that reset automatically in idle like DSS
- Ignore ti-sysc clockactivity bit unless separately requested
to avoid unexpected performance issues
- Init ti-sysc framedonetv_irq to true and disable for am4
- Avoid duplicate DSS reset for legacy mode with dts data
- Remove LCD timings for am4 as they cause warnings now that we're
using generic panels
Other OMAP changes from Tony include:
- Fix omap_prm reset deassert as we still have drivers setting the
pm_runtime_irq_safe() flag
- Flush posted write for ti-sysc enable and disable
- Fix droid4 spi related errors with spi flags
- Fix am335x USB range and a typo for softreset
- Fix dra7 timer nodes for clocks for IPU and DSP
- Drop duplicate mailboxes after mismerge for dra7
- Prevent pocketgeagle header line signal from accidentally setting
micro-SD write protection signal by removing the default mux
- Fix NFSroot flakeyness after resume for duover by switching the
smsc911x gpio interrupt to back to level sensitive
- Fix regression for omap4 clockevent source after recent system
timer changes
- Yet another ethernet regression fix for the "rgmii" vs "rgmii-rxid"
phy-mode
- One patch to convert am3/am4 DT files to use the regular sdhci-omap
driver instead of the old hsmmc driver, this was meant for the
merge window but got lost in the process.

Peter Zijlstra says:
These patches address a number of instrumentation issues that were found after
the x86/entry overhaul. When combined with rcu/urgent and objtool/urgent, these
patches make UBSAN/KASAN/KCSAN happy again.
Part of making this all work is bumping the minimum GCC version for KASAN
builds to gcc-8.3, the reason for this is that the __no_sanitize_address
function attribute is broken in GCC releases before that.
No known GCC version has a working __no_sanitize_undefined, however because the
only noinstr violation that results from this happens when an UB is found, we
treat it like WARN. That is, we allow it to violate the noinstr rules in order
to get the warning out.

Missed sdhci patch for am3 and am4
I forgot to send a pull request earlier for converting am3 and am4 to use sdhci-omap driver instead of the old omap_hsmmc driver. There was a display subsystem related suspend and resume regression found recently and looks like I forgot to send a pull request for this patch while debugging the regression.

Fixes for omaps for v5.8
The recent display subsystem (DSS) related platform data changes caused display related regressions for suspend and resume. Looks like I only tested suspend and resume before dropping the legacy platform data, and forgot to test it after dropping it. Turns out the main issue was that we no longer have platform code calling pm_runtime_suspend for DSS like we did for the legacy platform data case, and that fix is still being discussed on the dri-devel list and will get merged separately. The DSS related testing exposed a pile other other display related issues that also need fixing though: - Fix ti-sysc optional clock handling and reset status checks for devices that reset automatically in idle like DSS - Ignore ti-sysc clockactivity bit unless separately requested to avoid unexpected performance issues - Init ti-sysc framedonetv_irq to true and disable for am4 - Avoid duplicate DSS reset for legacy mode with dts data - Remove LCD timings for am4 as they cause warnings now that we're using generic panels Then there is a pile of other fixes not related to the DSS: - Fix omap_prm reset deassert as we still have drivers setting the pm_runtime_irq_safe() flag - Flush posted write for ti-sysc enable and disable - Fix droid4 spi related errors with spi flags - Fix am335x USB range and a typo for softreset - Fix dra7 timer nodes for clocks for IPU and DSP - Drop duplicate mailboxes after mismerge for dra7 -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEkgNvrZJU/QSQYIcQG9Q+yVyrpXMFAl7iS6oRHHRvbnlAYXRv bWlkZS5jb20ACgkQG9Q+yVyrpXPLLBAAzcABBnwfnk+vjSHJ9QnQ/9LfJTLUIrkH ZpB/CR6VC86STjpePaNpVN/fm5sODN4zvtpsuAvJgyF+9Hp3GRPxglC4g9cAmU8x VFQepzgOLOQ/ubPesVWa14RgAoK29GNvfzihCKGmhOq7kz7I/PDIQr8txjw8KHqV M8oVefWL6l95z1MwVEKvsebyloBwYx9q/+Q5bipoV/GvrQnMjaCFzEaO6n8nH0Xc T6XsKA+4hCr94tHM3jgfSdIQYFrq38H84t986ExMVfIhh3LfNkNu7CrSIWcjTgEY jAs/hnPQ/JzMuBivweCrfkpQYy4D/GOjueQJy2Mf3deMJUWEsgZzMOML743W307j HvGB5c3i1HgXir6PtjQFP4RqQQpQN1b4xjYEgvd8SB6xnrbdP43YsNrm9gnqbWd8 yNqiY2+uEh7OFyOJe0Ikrr1DNh3K0dSmtqrdhtWor165W0sAqlgjFjrjH1/xcQrN XWhjBCl/NAODNZqbxU4l6rjiSU8J0cGr8wJrZNLe4itZy9R2jPInTv8FSpfcNI32 cVdDfPc4SVl8zsfZq4vhDrS/JVG7Sp/DXXQIG04wMlA6vyK4YAHh0U40121aAE8E AwzOh++cCeZPQB+i3qCkRMLDohC7IJVvZZ/KN1mp43dDEW+epx5tct0ZmfElr4uX Vg84CHL/I28= =fT9A -----END PGP SIGNATURE----- Merge tag 'omap-for-v5.8/fixes-merge-window-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes Fixes for omaps for v5.8 The recent display subsystem (DSS) related platform data changes caused display related regressions for suspend and resume.

RISC-V Fixes for 5.8-rc3
This contains a handful of fixes I'd like to target for rc3. Most of them fix
issues with the conversion of our vDSO to C. There is also one fix to the
SiFive PRCI driver that I picked up as it's causing boot issues on the
hardware.
* A fix to allow kernels with dynamic ftrace to use the vDSO.
* Some build fixes for the C vDSO functions.
* A fix to the PRCI driver's memory allocation, which was the cause of some
boot panics with FREELIST_RANDOM.

Pull arm64 fixes from Will Deacon:
"The big fix here is to our vDSO sigreturn trampoline as, after a
painfully long stint of debugging, it turned out that fixing some of
our CFI directives in the merge window lit up a bunch of logic in
libgcc which has been shown to SEGV in some cases during asynchronous
pthread cancellation.
It looks like we can fix this by extending the directives to restore
most of the interrupted register state from the sigcontext, but it's
risky and hard to test so we opted to remove the CFI directives for
now and rely on the unwinder fallback path like we used to.
