The old dmascc driver depends on the legacy ISA_DMA_API, and blindly just casts the kernel virtual address to 'int' for set_dma_addr(). That works only incidentally, and because the high bits of the address will be ignored anyway. And on 64-bit architectures it causes warnings. Admittedly, 64-bit architectures with ISA are basically dead - I think the only example of this is alpha, and nobody would ever use the dmascc driver there. But hey, the fix is easy enough, the end result is cleaner, and it's yet another configuration that now builds without warnings. If somebody actually uses this driver on an alpha and this fixes it for you, please email me. Because that is just incredibly bizarre. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

With the previous commit (9caea000: "parisc: Declare pci_iounmap() parisc version only when CONFIG_PCI enabled") we can now enable GENERIC_PCI_IOMAP unconditionally on alpha, and if PCI is not enabled we will just get the nice empty helper functions that allow mixed-bus drivers to build. Example driver: the old 3com/3c59x.c driver works with either the PCI or the EISA version of the 3x59x card, but wouldn't build in an EISA-only configuration because of missing pci_iomap() and pci_iounmap() dummy wrappers. Most of the other PCI infrastructure just becomes empty wrappers even without GENERIC_PCI_IOMAP, and it's not obvious that the pci_iomap functionality shouldn't do the same, but this works.

Linus noticed odd declaration rules for pci_iounmap() in iomap.h and pci_iomap.h, where it dependend on either NO_GENERIC_PCI_IOPORT_MAP or GENERIC_IOMAP when CONFIG_PCI was disabled. Testing on parisc seems to indicate that we need pci_iounmap() only when CONFIG_PCI is enabled, so the declaration of pci_iounmap() can be moved cleanly into pci_iomap.h in sync with the declarations of pci_iomap().

We already had the implementation for __udiv_qrnnd (unsigned divide for multi-precision arithmetic) as part of the alpha math emulation code. But you can disable the math emulation code - even if you shouldn't - and then the MPI code that actually wants this functionality (and is needed by various crypto functions) will fail to build. So move the extended-precision divide code to be a regular library function, just like all the regular division code is. That way ie is available regardless of math-emulation.

Ok, it almost certainly is still broken on actual hardware, but the immediate reason for it having been marked BROKEN was a build error that is fixed by just making sure the low-level IO header file is included sufficiently early that the __EXTERN_INLINE hackery takes effect. This was marked broken back in 2017 by commit 1883c9f4 ("alpha: mark jensen as broken"), but Ulrich Teichert made me look at it as part of my cross-build work to make sure -Werror actually does the right thing. There are lots of alpha configurations that do not build cleanly, but now it's no longer because Jensen wouldn't be buildable. That said, because the Jensen platform doesn't force PCI to be enabled (Jensen only had EISA), it ends up being somewhat interesting as a source of odd configs.

The TGA boards were based on the DECchip 21030 PCI graphics accelerator used mainly for alpha, and existed in a TURBOchannel (TC) version for the DECstation (MIPS) workstations. However, the config option for the TGA code is a bit confused, and says depends on FB && (ALPHA || TC) because people didn't really want to enable the option for random PCI environments, so the "ALPHA" stands in for that case (while the TC case is then the MIPS DECstation case). So that config dependency is kind of a mixture of architecture and bus choices. But it's incorrect, in that there were non-PCI-based alpha hardware, and then the driver just causes warnings: drivers/video/fbdev/tgafb.c:1532:13: error: ‘tgafb_unregister’ defined but not used [-Werror=unused-function] 1532 | static void tgafb_unregister(struct device *dev) | ^~~~~~~~~~~~~~~~ drivers/video/fbdev/tgafb.c:1387:12: error: ‘tgafb_register’ defined but not used [-Werror=unused-function] 1387 | static int tgafb_register(struct device *dev) | ^~~~~~~~~~~~~~ so let's make the config option dependencies a bit more explict: depends on FB depends on PCI || TC depends on ALPHA || TC where that first "FB" is the software configuration dependency, the second "PCI || TC" is the hardware bus dependency, while that final "ALPHA || TC" dependency is the "don't bother asking except for these situations. We could make that third case have "COMPILE_TEST" as an option, and mark the register/unregister functions as __maybe_unused, but I'm not sure it's really worth it.

The Jensen IO functions are overly copmplicated because some of the IO addresses refer to special 'local IO' ports, and they get accessed differently. That then makes gcc not actually inline them, and since they were marked "extern inline" when included through the regular <asm/io.h> path, and then only marked "inline" when included from sys_jensen.c, you never necessarily got a body for the IO functions at all. The intent of the sys_jensen.c code is to actually get the non-inlined copy generated, so remove the 'inline' from the magic macro that is supposed to sort this all out. Also, do not mix 'extern inline' functions (that may or may not be inlined and will not generate a function body if they are not) with 'static inline' (that _will_ generate a function body when not inlined). Because gcc will complain about this situation: error: ‘jensen_bus_outb’ is static but used in inline function ‘jensen_outb’ which is not static because gcc basically doesn't know whether to generate a body for that static inline function or not for that call site. So make all of these use that __EXTERN_INLINE marker. Gcc will generally not inline these things on use, and then generate the function body out-of-line in sys_jensen.c. This makes the core IO functions build for the alpha Jensen config. Not that the rest then builds, because it turns out Jensen also doesn't enable PCI, which then makes other drievrs very unhappy, but that's a separate issue.

Pull io_uring iov_iter retry fixes from Jens Axboe: "This adds a helper to save/restore iov_iter state, and modifies io_uring to use it. After that is done, we can now kill the iter->truncated addition that we added for this release. The io_uring change is being overly cautious with the save/restore/advance, but better safe than sorry and we can always improve that and reduce the overhead if it proves to be of concern. The only case to be worried about in this regard is huge IO, where iteration can take a while to iterate segments. I spent some time writing test cases, and expanded the coverage quite a bit from the last posting of this. liburing carries this regression test case now: https://git.kernel.dk/cgit/liburing/tree/test/file-verify.c which exercises all of this. It now also supports provided buffers, and explicitly tests for end-of-file/device truncation as well.

tx timeout and slot time are currently specified in units of HZ. On Alpha, HZ is defined as 1024. When building alpha:allmodconfig, this results in the following error message. drivers/net/hamradio/6pack.c: In function 'sixpack_open': drivers/net/hamradio/6pack.c:71:41: error: unsigned conversion from 'int' to 'unsigned char' changes value from '256' to '0' In the 6PACK protocol, tx timeout is specified in units of 10 ms and transmitted over the wire: https://www.linux-ax25.org/wiki/6PACK Defining a value dependent on HZ doesn't really make sense, and presumably comes from the (very historical) situation where HZ was originally 100. Note that the SIXP_SLOTTIME use explicitly is about 10ms granularity: mod_timer(&sp->tx_t, jiffies + ((when + 1) * HZ) / 100); and the SIXP_TXDELAY walue is sent as a byte over the wire.

Fixes a very annoying issue where the driver view of the MMU state gets out of sync with the actual hardware state across a runtime PM cycle, so we end up restarting the GPU with the wrong (potentially already freed) MMU context.

With the new static annotation, the compiler warns when the functions are actually unused: drivers/gpu/drm/rockchip/cdn-dp-core.c:1123:12: error: 'cdn_dp_resume' defined but not used [-Werror=unused-function] 1123 | static int cdn_dp_resume(struct device *dev) | ^~~~~~~~~~~~~ Mark them __maybe_unused to suppress that warning as well. [ Not so 'new' static annotations any more, and I removed the part of the patch that added __maybe_unused to cdn_dp_suspend(), because it's used by the shutdown/remove code. So only the resume function ends up possibly unused if CONFIG_PM isn't set - Linus ] Fixes: 7c49abb4 ("drm/rockchip: cdn-dp-core: Make cdn_dp_core_suspend/resume static") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Some drivers pass a pointer to volatile data to virt_to_bus() and virt_to_phys(), and that works fine. One exception is alpha. This results in a number of compile errors such as drivers/net/wan/lmc/lmc_main.c: In function 'lmc_softreset': drivers/net/wan/lmc/lmc_main.c:1782:50: error: passing argument 1 of 'virt_to_bus' discards 'volatile' qualifier from pointer target type drivers/atm/ambassador.c: In function 'do_loader_command': drivers/atm/ambassador.c:1747:58: error: passing argument 1 of 'virt_to_bus' discards 'volatile' qualifier from pointer target type Declare the parameter of virt_to_phys and virt_to_bus as pointer to volatile to fix the problem.

This driver isn't enabled most places because of the ISA config dependency, but alpha still has it. And I think the 'Jensen' actually did have an ISA slot. However, it doesn't build cleanly, because the "Vortex bus master" code just casts the skb->data pointer to 'int': outl((int) (skb->data), ioaddr + Wn7_MasterAddr); which is all kinds of broken. Even on a good old traditional PC/AT it would be broken because the high bits will be random kernel address bits, but presumably the hardware ignores those bits. I mean, it's ISA. We're talking 16MB dma limits. The "good old days". Make the build happy with this kind of craziness by using the proper isa_virt_to_bus() handling that the full bus master code uses anyway (the Vortex bus mastering is a limited special case). Who knows, this might even work. Reported-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

__stack_chk_guard is setup once while init stage and never changed after that. Although the modification of this variable at runtime will usually cause the kernel to crash (so does the attacker), it should be marked as __ro_after_init, and it should not affect performance if it is placed in the ro_after_init section.

When we need a buffer for SVE register state we call sve_alloc() to make sure that one is there. In order to avoid repeated allocations and frees we keep the buffer around unless we change vector length and just memset() it to ensure a clean register state. The function that deals with this takes the task to operate on as an argument, however in the case where we do a memset() we initialise using the SVE state size for the current task rather than the task passed as an argument. This is only an issue in the case where we are setting the register state for a task via ptrace and the task being configured has a different vector length to the task tracing it. In the case where the buffer is larger in the traced process we will leak old state from the traced process to itself, in the case where the buffer is smaller in the traced process we will overflow the buffer and corrupt memory.
