Pull staging driver updates from Greg KH: "Here is the big set of staging driver updates for 7.2-rc1. Nothing major in here, just constant grind of tiny cleanups and coding style fixes and wrapper removals. Overall more code was removed than added, always a nice sign that things are progressing forward. Changes outside of drivers/staging/ was due to the octeon driver changes, which for some reason also lives partially in the mips subsystem, someday that all will be untangled and cleaned up, or just removed entirely, it's hard to tell which is going to be its fate. Other than octeon driver cleanups, in here are the usual: - rtl8723bs driver reworking and cleanups, being the bulk of this merge window given all of the issues and wrappers involved in that beast of a driver - most driver cleanups - sm750fb driver cleanups (which might be done, as this really should be moved to the drm layer one of these days...) - other tiny staging driver cleanups and fixes All of these have been in linux-next for many weeks with no reported issues" * tag 'staging-7.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (199 commits) staging: most: video: avoid double free on video register failure staging: sm750: rename CamelCase variable Bpp to bpp staging: rtl8723bs: delete superfluous switch statement staging: sm750fb: Mark g_noaccel, g_nomtrr and g_dualview as __ro_after_init staging: rtl8723bs: propagate errno through hal xmit path staging: rtl8723bs: propagate errno through xmit enqueue path staging: rtl8723bs: convert rtw_xmit_classifier to return errno staging: rtl8723bs: make rtw_xmit_classifier static staging: rtl8723bs: simplify rtw_xmit_classifier control flow staging: rtl8723bs: make _rtw_enqueue_cmd return 0 on success staging: rtl8723bs: simplify rtw_enqueue_cmd control flow staging: rtl8723bs: make _rtw_enqueue_cmd static staging: rtl8723bs: simplify _rtw_enqueue_cmd control flow staging: rtl8723bs: fix multiple blank lines in more hal/ files staging: rtl8723bs: remove unused TXDESC_64_BYTES code staging: rtl8723bs: remove unused DBG_XMIT_BUF and DBG_XMIT_BUF_EXT code staging: rtl8723bs: fix multiple blank lines in hal/Hal* files staging: rtl8723bs: fix multiple blank lines in hal/ files staging: rtl8723bs: rtw_mlme: add blank line for readability staging: rtl8723bs: rtw_mlme: wrap rtw_sitesurvey_cmd condition ...

MIPS: ath79: reduce ARCH_DMA_MINALIGN

2026-06-15T10:12:24+00:00

Currently, ath79 SoCs use the default ARCH_DMA_MINALIGN value of 128 bytes defined in mach-generic. This is excessive for these platforms and leads to significant memory waste in kmalloc. Override ARCH_DMA_MINALIGN to use L1_CACHE_BYTES, which is 32 bytes for ath79 SoCs. Signed-off-by: Rosen Penev Signed-off-by: Thomas Bogendoerfer

uaccess: unify inline vs outline copy_{from,to}_user() selection

2026-05-29T04:24:44+00:00

The kernel allows arches to select between inline and outline implementations of the copy_{from,to}_user() by defining individual INLINE_COPY_FROM_USER and INLINE_COPY_TO_USER, correspondingly. However, all arches enable or disable them always together. Without the real use-case for one helper being inlined while the other outlined, having independent controls is excessive and error prone. Switch the codebase to the single unified INLINE_COPY_USER control.

MIPS: alchemy: mtx1: attach software nodes to GPIO chips

2026-05-27T07:52:35+00:00

GPIO subsystem is switching the way it locates GPIO chip instances for GPIO references in software nodes from matching on node names to identity matching, which necessitates assigning firmware nodes (software nodes) to GPIO chips. Move the node definitions for alchemy-gpio1 and alchemy-gpio2 to arch/misp/alchemy/common/gpiolib.c, register them there, and attach them to gpio_chip instances. Adjust MTX1 board file to use these nodes. Note that because nodes need to be registered before they can be used in PROPERTY_ENTRY_GPIO() we have to do the registration at postcore_initcall level, otherwise (due to the link order) MTX1 board initialization code will run first.

MIPS: DEC: Ensure 32-bit stack location for o32 prom_printf()

2026-05-26T14:35:36+00:00

In 64-bit configurations calling any firmware entry points from a kernel thread other than the initial one will result in a situation where the stack has been placed in the XKPHYS 64-bit memory segment. Consequently the stack pointer is no longer a 32-bit value and when the 32-bit firmware code called uses 32-bit ALU operations to manipulate the stack pointer, the calculated result is incorrect (in fact in the 64-bit MIPS ISA almost all 32-bit ALU operations will produce an unpredictable result when executed on 64-bit data) and control goes astray. This may happen when no final console driver has been enabled in the configuration and consequently the initial console continues being used late into bootstrap, or with an upcoming change that will switch the zs driver to use a platform device, which in turn will make the console handover happen only after other kernel threads have already been started, and the kernel will hang at: pid_max: default: 32768 minimum: 301 or somewhat later, but always before: cblist_init_generic: Setting adjustable number of callback queues. has been printed. It seems that only the prom_printf() entry point is affected. Of all the other entry points wired only rex_slot_address() and rex_gettcinfo() are called from a kernel thread other than the initial one, specifically kernel_init(), and they are leaf functions that do no business with the stack, having worked with no issue ever since 64-bit support was added for the platform back in 2002. To address this issue then, arrange for the stack to be switched in the o32 wrapper as required for prom_printf() only, by supplying call_o32() with a pointer to a chunk of initdata space, which is placed in the CKSEG0 32-bit compatibility segment, observing that prom_printf() is only called from console output handler and therefore with the console lock held, implying no need for this code to be reentrant. Other firmware entry points may be called with interrupts enabled and no lock held, and may therefore require that call_o32() be reentrant. They trigger no issue at this point and "if it ain't broke, don't fix it," so just leave them alone. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Maciej W.
