2019-10-11Documentation/process: Add fallthrough pseudo-keywordJoe Perches2-11/+24
Describe the fallthrough pseudo-keyword. Convert the coding-style.rst example to the keyword style. Add description and links to deprecated.rst. Miguel Ojeda comments on the eventual [[fallthrough]] syntax: "Note that C17/C18 does not have [[fallthrough]]. C++17 introduced it, as it is mentioned above. I would keep the __attribute__((fallthrough)) -> [[fallthrough]] change you did, though, since that is indeed the standard syntax (given the paragraph references C++17). I was told by Aaron Ballman (who is proposing them for C) that it is more or less likely that it becomes standardized in C2x. However, it is still not added to the draft (other attributes are already, though). See N2268 and N2269: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2268.pdf (fallthrough) http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2269.pdf (attributes in general)" Signed-off-by: Joe Perches <[email protected]> Acked-by: Nick Desaulniers <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2019-10-11compiler_attributes.h: Add 'fallthrough' pseudo keyword for switch/case useJoe Perches1-0/+17
Reserve the pseudo keyword 'fallthrough' for the ability to convert the various case block /* fallthrough */ style comments to appear to be an actual reserved word with the same gcc case block missing fallthrough warning capability. All switch/case blocks now should end in one of: break; fallthrough; goto <label>; return [expression]; continue; In C mode, GCC supports the __fallthrough__ attribute since 7.1, the same time the warning and the comment parsing were introduced. fallthrough devolves to an empty "do {} while (0)" if the compiler version (any version less than gcc 7) does not support the attribute.

Depending on inlining decisions by the compiler, __get/put_user_fn might become out of line. Then the compiler is no longer able to tell that size can only be 1,2,4 or 8 due to the check in __get/put_user resulting in false positives like ./arch/s390/include/asm/uaccess.h: In function ‘__put_user_fn’: ./arch/s390/include/asm/uaccess.h:113:9: warning: ‘rc’ may be used uninitialized in this function [-Wmaybe-uninitialized] 113 | return rc; | ^~ ./arch/s390/include/asm/uaccess.h: In function ‘__get_user_fn’: ./arch/s390/include/asm/uaccess.h:143:9: warning: ‘rc’ may be used uninitialized in this function [-Wmaybe-uninitialized] 143 | return rc; | ^~ These functions are supposed to be always inlined.

2019-10-11firmware: google: increment VPD key_len properlyBrian Norris1-1/+1
Commit 4b708b7b1a2c ("firmware: google: check if size is valid when decoding VPD data") adds length checks, but the new vpd_decode_entry() function botched the logic -- it adds the key length twice, instead of adding the key and value lengths separately. On my local system, this means vpd.c's vpd_section_create_attribs() hits an error case after the first attribute it parses, since it's no longer looking at the correct offset. With this patch, I'm back to seeing all the correct attributes in /sys/firmware/vpd/...

We have two ways a request can be deferred: 1) It's a regular request that depends on another one 2) It's a timeout that tracks completions We have a shared helper to determine whether to defer, and that attempts to make the right decision based on the request. But we only have some of this information in the caller. Un-share the two timeout/defer helpers so the caller can use the right one.

2019-10-10SUNRPC: fix race to sk_err after xs_error_reportBenjamin Coddington2-9/+9
Since commit 4f8943f80883 ("SUNRPC: Replace direct task wakeups from softirq context") there has been a race to the value of the sk_err if both XPRT_SOCK_WAKE_ERROR and XPRT_SOCK_WAKE_DISCONNECT are set. In that case, we may end up losing the sk_err value that existed when xs_error_report was called. Fix this by reverting to the previous behavior: instead of using SO_ERROR to retrieve the value at a later time (which might also return sk_err_soft), copy the sk_err value onto struct sock_xprt, and use that value to wake pending tasks.

2019-10-10MIPS: Disable Loongson MMI instructions for kernel buildPaul Burton2-0/+5
GCC 9.x automatically enables support for Loongson MMI instructions when using some -march= flags, and then errors out when -msoft-float is specified with: cc1: error: ‘-mloongson-mmi’ must be used with ‘-mhard-float’ The kernel shouldn't be using these MMI instructions anyway, just as it doesn't use floating point instructions.

2019-10-10nbd: fix possible sysfs duplicate warningXiubo Li1-1/+1
1. nbd_put takes the mutex and drops nbd->ref to 0. It then does idr_remove and drops the mutex. 2. nbd_genl_connect takes the mutex. idr_find/idr_for_each fails to find an existing device, so it does nbd_dev_add. 3. just before the nbd_put could call nbd_dev_remove or not finished totally, but if nbd_dev_add try to add_disk, we can hit: debugfs: Directory 'nbd1' with parent 'block' already present! This patch will make sure all the disk add/remove stuff are done by holding the nbd_index_mutex lock.

2019-10-10xen: Stop abusing DT of_dma_configure APIRob Herring2-21/+4
As the removed comments say, these aren't DT based devices. of_dma_configure() is going to stop allowing a NULL DT node and calling it will no longer work. The comment is also now out of date as of commit 9ab91e7c5c51 ("arm64: default to the direct mapping in get_arch_dma_ops"). Direct mapping is now the default rather than dma_dummy_ops. According to Stefano and Oleksandr, the only other part needed is setting the DMA masks and there's no reason to restrict the masks to 32-bits. So set the masks to 64 bits.
