It was only checking the divider when determing the closest match if it could not match the requested rate exactly. For a projector connected to an Olimex A20-OLinuXino-LIME using HDMI with a native resolution of 1280x800 and pixel clock of 83.5 MHz, this resulted in 1280x800 mode not being available and the following in dmesg when the kernel is booted with drm.debug=0x3e: [drm:drm_mode_debug_printmodeline] Modeline 37:"1280x800" 60 83500 1280 1352 1480 1680 800 810 816 831 0x48 0x5 [drm:drm_mode_prune_invalid] Not using 1280x800 mode: NOCLOCK Fixes: 9c568101 ("drm/sun4i: Add HDMI support") Signed-off-by: Jonathan Liu <net147@gmail.com> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180109020323.11852-4-net147@gmail.com

best_div is set to i which corresponds to rate halving when it should be set to j which corresponds to the divider.

It is possible that if there is no exact rate match and "rounded = clk_hw_round_rate(parent, ideal)" gives high enough values (e.g. if rounded is 2 * ideal) that the condition "abs(rate - rounded / i) < abs(rate - best_parent / best_div)" is never met and best_parent is never set. This results in req->rate and req->best_parent_rate being assigned 0. To avoid this, we set best_parent to the first calculated rate if it is unset. The sun4i_tmds_calc_divider function already has a similar check.

Jacek Anaszewski authored
Commit 2b83ff96 ("led: core: Fix brightness setting when setting delay_off=0") replaced del_timer_sync(&led_cdev->blink_timer) with led_stop_software_blink() in led_blink_set(), which additionally clears LED_BLINK_SW flag as well as zeroes blink_delay_on and blink_delay_off properties of the struct led_classdev. Cleansing of the latter ones wasn't required to fix the original issue but wasn't considered harmful. It nonetheless turned out to be so in case when pointer to one or both props is passed to led_blink_set() like in the ledtrig-timer.c. In such cases zeroes are passed later in delay_on and/or delay_off arguments to led_blink_setup(), which results either in stopping the software blinking or setting blinking frequency always to 1Hz. Avoid using led_stop_software_blink() and add a single call required to clear LED_BLINK_SW flag, which was the only needed modification to fix the original issue.

In the current driver, OOB bytes are accessed in raw mode, and when a page access is done with NDCR_SPARE_EN set and NDCR_ECC_EN cleared, the driver must read the whole spare area (64 bytes in case of a 2k page, 16 bytes for a 512 page). The driver was only reading the free OOB bytes, which was leaving some unread data in the FIFO and was somehow leading to a timeout. We could patch the driver to read ->spare_size + ->ecc_size instead of just ->spare_size when READOOB is requested, but we'd better make in-band and OOB accesses consistent. Since the driver is always accessing in-band data in non-raw mode (with the ECC engine enabled), we should also access OOB data in this mode. That's particularly useful when using the BCH engine because in this mode the free OOB bytes are also ECC protected.

The subject line of the commit tells it the other way around, but I noticed that too late. - Fix the ASM alternative macros so they can be used in the middle of an inline asm block. - Rename the BUG_CPU_INSECURE flag to BUG_CPU_MELTDOWN so the attack vector is properly identified.

The previous fix in commit 384632e6 ("userfaultfd: non-cooperative: fix fork use after free") corrected the refcounting in case of UFFD_EVENT_FORK failure for the fork userfault paths. That still didn't clear the vma->vm_userfaultfd_ctx of the vmas that were set to point to the aborted new uffd ctx earlier in dup_userfaultfd.

In commit 83e3c487 ("mm/sparsemem: Allocate mem_section at runtime for CONFIG_SPARSEMEM_EXTREME=y") mem_section is allocated at runtime to save memory. It allocates the first dimension of array with sizeof(struct mem_section). It costs extra memory, should be sizeof(struct mem_section *). Fix it.
