After emulating an unaligned access in delay slot of a branch, we pretend as the delay slot never happened - so return back to actual branch target (or next PC if branch was not taken). Curently we did this by handling STATUS32.DE, we also need to clear the BTA.T bit, which is disregarded when returning from original misaligned exception, but could cause weirdness if it took the interrupt return path (in case interrupt was acive too) One ARC700 customer ran into this when enabling unaligned access fixup for kernel mode accesses as well Cc: stable@vger.kernel.org Signed-off-by:

This is needed on HS38 cores, for setting up IO-Coherency aperture properly The polling could perturb the caches and coherecy fabric which could be wrong in the small window when Master is setting up IOC aperture etc in arc_cache_init() We do it only for ARCv2 based builds to not affect EZChip ARCompact based platform.

For run-on-reset SMP configs, non master cores call a routine which waits until Master gives it a "go" signal (currently using a shared mem flag). The same routine then jumps off the well known entry point of all non Master cores i.e. @first_lines_of_secondary This patch moves out the last part into one single place in early boot code. This is better in terms of absraction (the wait API only waits) and returns, leaving out the "jump off to" part. In actual implementation this requires some restructuring of the early boot code as well as Master now jumps to BSS setup explicitly, vs. falling thru into it before. Technically this patch doesn't cause any functional change, it just moves the ugly #ifdef'ry from assembly code to "C" Signed-off-by:

commit 3c7c7a2f ("ARC: Don't use "+l" inline asm constraint") modified the inline assembly to setup LP_COUNT register manually and NOT rely on gcc to do it (with the +l inline assembler contraint hint, now being retired in the compiler) However the fix was flawed as we didn't add LP_COUNT to asm clobber list, meaning gcc doesn't know that LP_COUNT or zero-delay-loops are in action in the inline asm. This resulted in some fun - as nested ZOL loops were being generared | mov lp_count,250000 ;16 # tmp235, | lp .L__GCC__LP14 # <======= OUTER LOOP (gcc generated) | .L14: | ld r2, [r5] # MEM[(volatile u32 *)prephitmp_43], w | dmb 1 | breq r2, -1, @.L21 #, w,, | bbit0 r2,1,@.L13 # w,, | ld r4,[r7] ;25 # loops_per_jiffy, loops_per_jiffy | mpymu r3,r4,r6 #, loops_per_jiffy, tmp234 | | mov lp_count, r3 # <====== INNER LOOP (from inline asm) | lp 1f | nop | 1: | nop_s | .L__GCC__LP14: ; loop end, start is @.L14 #, This caused issues with drivers relying on sane behaviour of udelay friends. With LP_COUNT added to clobber list, gcc doesn't generate the outer loop in say above case. Addresses STAR 9001146134 Reported-by:

Ignore value of interrupt distribution mode for common interrupts in IDU since setting of affinity using value from Device Tree is deprecated in ARC. Originally it is done in idu_irq_xlate() function and it is semantically wrong and does not guaranty that an affinity value will be set properly. idu_irq_enable() function is better place for initialization of common interrupts. By default send all common interrupts to all available online CPUs. The affinity of common interrupts in IDU must be set manually since in some cases the kernel will not call irq_set_affinity() by itself: 1. When the kernel is not configured with support of SMP. 2. When the kernel is configured with support of SMP but upper interrupt controllers does not support setting of the affinity and cannot propagate it to IDU. Signed-off-by:

Christian Borntraeger authored
kvm_s390_get_machine() populates the facility bitmap by copying bytes from the host results that are stored in a 256 byte array in the prefix page. The KVM code does use the size of the target buffer (2k), thus copying and exposing unrelated kernel memory (mostly machine check related logout data). Let's use the size of the source buffer instead. This is ok, as the target buffer will always be greater or equal than the source buffer as the KVM internal buffers (and thus S390_ARCH_FAC_LIST_SIZE_BYTE) cover the maximum possible size that is allowed by STFLE, which is 256 doublewords. All structures are zero allocated so we can leave bytes 256-2047 unchanged. Add a similar fix for kvm_arch_init_vm(). Reported-by:

The warn on is a bit too much, we will anyway set the dma mask if not set previously. The main reason for this fix is that 4.10-rc1 has a dwc3 change that pass a parent sysdev dev pointer instead of setting the dma mask of its xhci platform device. xhci platform driver can then get more attributes from the sysdev than just the dma mask. The usb core and xhci changes are not yet in 4.10, and a fix like this was preferred instead of taking those big changes this late in the rc-cycle. Signed-off-by:

IBM bit 31 (for the rest of us - bit 0) is a reserved field in the instruction definition of mtspr and mfspr. Hardware is encouraged to (and does) ignore it. As a result, if userspace executes an mtspr DSCR with the reserved bit set, we get a DSCR facility unavailable exception. The kernel fails to match against the expected value/mask, and we silently return to userspace to try and re-execute the same mtspr DSCR instruction. We loop forever until the process is killed. We should do something here, and it seems mirroring what hardware does is the better option vs killing the process. While here, relax the matching of mfspr PVR too.

Read access to the SPI flash are broken on da850-evm, i.e. the data read is not what is actually programmed on the flash. According to the datasheet for the M25P64 part present on the da850-evm, if the SPI frequency is higher than 20MHz then the READ command is not usable anymore and only the FAST_READ command can be used to read data. This commit specifies in the DTS that we should use FAST_READ command instead of the READ command. Cc: stable@vger.kernel.org Tested-by:

As virtio-1 introduced the possibility of the device manipulating the status byte, revision 2 of the virtio-ccw transport introduced a means of getting the status byte from the device via READ_STATUS. Let's wire it up for revisions >= 2 and fall back to returning the stored status byte if not supported. Signed-off-by:

Since ef1b144d ("tools/virtio/ringtest: fix run-on-all.sh to work without /dev/cpu") run-on-all.sh uses seq 0 $HOST_AFFINITY as the list of ids of the CPUs to run the command on (assuming ids of online CPUs are consecutive and start from 0), where $HOST_AFFINITY is the highest CPU id in the system previously determined using lscpu. This can fail on systems with offline CPUs. Instead let's use lscpu to determine the list of online CPUs. Signed-off-by:
