Pull RISC-V fixes from Paul Walmsley: "Minor RISC-V fixes and one defconfig update. The fixes have no functional impact: - Fix some comment text in the memory management vmalloc_fault path. - Fix some warnings from the DT compiler in our newly-added DT files. - Change the newly-added DT bindings such that SoC IP blocks with external I/O are marked as "disabled" by default, then enable them explicitly in board DT files when the devices are used on the board. This aligns the bindings with existing upstream practice. - Add the MIT license as an option for a minor header file, at the request of one of the U-Boot maintainers. The RISC-V defconfig update builds the SiFive SPI driver and the MMC-SPI driver by default. The intention here is to make v5.2 more usable for testers and users with RISC-V hardware" * tag 'riscv-for-v5.2/fixes-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: mm: Fix code comment dt-bindings: clock: sifive: add MIT license as an option for the header file dt-bindings: riscv: resolve 'make dt_binding_check' warnings riscv: dts: Re-organize the DT nodes RISC-V: defconfig: enable MMC & SPI for RISC-V

linux/kernel.h: fix overflow for DIV_ROUND_UP_ULL

2019-06-29T08:43:45+00:00

DIV_ROUND_UP_ULL adds the two arguments and then invokes DIV_ROUND_DOWN_ULL. But on a 32bit system the addition of two 32 bit values can overflow. DIV_ROUND_DOWN_ULL does it correctly and stashes the addition into a unsigned long long so cast the result to unsigned long long here to avoid the overflow condition. [akpm@linux-foundation.org: DIV_ROUND_UP_ULL must be an rval] Link: http://lkml.kernel.org/r/20190625100518.30753-1-vkoul@kernel.org Signed-off-by: Vinod Koul Reviewed-by: Andrew Morton Cc: Bjorn Andersson Cc: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

signal: remove the wrong signal_pending() check in restore_user_sigmask()

2019-06-29T08:43:45+00:00

This is the minimal fix for stable, I'll send cleanups later. Commit 854a6ed56839 ("signal: Add restore_user_sigmask()") introduced the visible change which breaks user-space: a signal temporary unblocked by set_user_sigmask() can be delivered even if the caller returns success or timeout. Change restore_user_sigmask() to accept the additional "interrupted" argument which should be used instead of signal_pending() check, and update the callers. Eric said: : For clarity. I don't think this is required by posix, or fundamentally to : remove the races in select. It is what linux has always done and we have : applications who care so I agree this fix is needed. : : Further in any case where the semantic change that this patch rolls back : (aka where allowing a signal to be delivered and the select like call to : complete) would be advantage we can do as well if not better by using : signalfd. : : Michael is there any chance we can get this guarantee of the linux : implementation of pselect and friends clearly documented. The guarantee : that if the system call completes successfully we are guaranteed that no : signal that is unblocked by using sigmask will be delivered?

mm/dev_pfn: exclude MEMORY_DEVICE_PRIVATE while computing virtual address

2019-06-29T08:43:44+00:00

The presence of struct page does not guarantee linear mapping for the pfn physical range. Device private memory which is non-coherent is excluded from linear mapping during devm_memremap_pages() though they will still have struct page coverage. Change pfn_t_to_virt() to just check for device private memory before giving out virtual address for a given pfn. pfn_t_to_virt() actually has no callers. Let's fix it for the 5.2 kernel and remove it in 5.3.
