[PATCH 2/2] hugetlb: optimize update_and_free_pages_bulk to avoid lock cycles

by Mike Kravetz

update_and_free_pages_bulk is designed to free a list of hugetlb pages back to their associated lower level allocators. This may require allocating vmemmmap pages associated with each hugetlb page. The hugetlb page destructor must be changed before pages are freed to lower level allocators. However, the destructor must be changed under the hugetlb lock. This means there is potentially one lock cycle per page. Minimize the number of lock cycles in update_and_free_pages_bulk by: 1) allocating necessary vmemmap for all hugetlb pages on the list 2) take hugetlb lock and clear destructor for all pages on the list 3) free all pages on list back to low level allocators Fixes: ad2fa3717b74 ("mm: hugetlb: alloc the vmemmap pages associated with each HugeTLB page") Cc: <stable(a)vger.kernel.org> Signed-off-by: Mike Kravetz <mike.kravetz(a)oracle.com> --- mm/hugetlb.c | 35 ++++++++++++++++++++++++++++++++++- 1 file changed, 34 insertions(+), 1 deletion(-) diff --git a/mm/hugetlb.c b/mm/hugetlb.c index 1b67bf341c32..e751fced870a 100644 --- a/mm/hugetlb.c +++ b/mm/hugetlb.c @@ -1856,11 +1856,44 @@ static void update_and_free_pages_bulk(struct hstate *h, struct list_head *list) { struct page *page, *t_page; struct folio *folio; + bool clear_dtor = false; + /* + * First allocate required vmemmmap for all pages on list.

[PATCH] ASoC: fsl_sai: Revert "ASoC: fsl_sai: Enable MCTL_MCLK_EN bit for master mode"

by Fabio Estevam

From: Fabio Estevam <festevam(a)denx.de> This reverts commit ff87d619ac180444db297f043962a5c325ded47b. Andreas reports that on an i.MX8MP-based system where MCLK needs to be used as an input, the MCLK pin is actually an output, despite not having the 'fsl,sai-mclk-direction-output' property present in the devicetree. This is caused by commit ff87d619ac18 ("ASoC: fsl_sai: Enable MCTL_MCLK_EN bit for master mode") that sets FSL_SAI_MCTL_MCLK_EN unconditionally for imx8mm/8mn/8mp/93, causing the MCLK to always be configured as output. FSL_SAI_MCTL_MCLK_EN corresponds to the MOE (MCLK Output Enable) bit of register MCR and the drivers sets it when the 'fsl,sai-mclk-direction-output' devicetree property is present. Revert the commit to allow SAI to use MCLK as input as well.

[RESEND] gpio: ws16c48: Fix off-by-one error in WS16C48 resource region extent

by William Breathitt Gray

The WinSystems WS16C48 I/O address region spans offsets 0x0 through 0xA, which is a total of 11 bytes. Fix the WS16C48_EXTENT define to the correct value of 11 so that access to necessary device registers is properly requested in the ws16c48_probe() callback by the devm_request_region() function call.
