This fix alters the minimum and maximum BUCK voltage limits for DA9052 and DA9053. It does so for the following cases: DA9052 - BUCK3 (MEM) min: 0.925V -> 0.950V max: 2.500V -> 2.525V DA9053 - BUCK3 (MEM) min: 0.925V -> 0.950V max: 2.500V -> 2.525V - BUCK4 (PERI) min: 0.925V -> 0.950V max: 2.500V -> 2.525V The voltage range remains the same, but the limits are shifted by +0.025V. This change is provided on DA9052:MEM, DA9053:MEM and DA9053:PERI and is a voltage difference of 0.025V, compared to those measured before this fix is applied. The patch has the effect of decreasing *all* measured voltages on those BUCKs when compared against the previously measured values for the same software voltage request. For example, with this fix applied for DA9052:MEM, DA9053:MEM and DA9053:PERI, the following is true. Because the previous software defined slot 0 as being 0.925V, if a request for 0.950V was previously sent, the slot 1 voltage would have been used. This would have corresponded to an actual measured voltage of 0.975V. But, with this patch fix, and with slot 0 properly aligned to 0.950V, if a voltage of 0.950V is requested by software, a measured value of 0.950V will be provided. Tested-by:

Interestingly, the second range ends at the correct value when it's set to be the appropriate start value, 1575000: 1575000 + ((158 - 96) * 25000) == 3125000 Signed-off-by:

The well-spotted fallocate undo fix is good in most cases, but not when fallocate failed on the very first page. index 0 then passes lend -1 to shmem_undo_range(), and that has two bad effects: (a) that it will undo every fallocation throughout the file, unrestricted by the current range; but more importantly (b) it can cause the undo to hang, because lend -1 is treated as truncation, which makes it keep on retrying until every page has gone, but those already fully instantiated will never go away. Big thank you to xfstests generic/269 which demonstrates this. Fixes: b9b4bb26 ("tmpfs: don't undo fallocate past its last page") Cc: stable@vger.kernel.org Signed-off-by:

As of Xen 4.7 PV CPUID doesn't expose either of CPUID[1].ECX[7] and CPUID[0x80000007].EDX[7] anymore, causing the driver to fail to load on both Intel and AMD systems. Doing any kind of hardware capability checks in the driver as a prerequisite was wrong anyway: With the hypervisor being in charge, all such checking should be done by it. If ACPI data gets uploaded despite some missing capability, the hypervisor is free to ignore part or all of that data. Ditch the entire check_prereq() function, and do the only valid check (xen_initial_domain()) in the caller in its place. Signed-off-by:

xenbus_dev_request_and_reply() needs to track whether a transaction is open. For XS_TRANSACTION_START messages it calls transaction_start() and for XS_TRANSACTION_END messages it calls transaction_end(). If sending an XS_TRANSACTION_START message fails or responds with an an error, the transaction is not open and transaction_end() must be called. If sending an XS_TRANSACTION_END message fails, the transaction is still open, but if an error response is returned the transaction is closed. Commit 027bd7e8 ("xen/xenbus: Avoid synchronous wait on XenBus stalling shutdown/restart") introduced a regression where failed XS_TRANSACTION_START messages were leaving the transaction open. This can cause problems with suspend (and migration) as all transactions must be closed before suspending. It appears that the problematic change was added accidentally, so just remove it.

When proc_pid_attr_write() was changed to use memdup_user apparmor's (interface violating) assumption that the setprocattr buffer was always a single page was violated. The size test is not strictly speaking needed as proc_pid_attr_write() will reject anything larger, but for the sake of robustness we can keep it in. SMACK and SELinux look safe to me, but somebody else should probably have a look just in case.
