[PATCH v3 4/10] x86/asm: Add pud_pgprot() and pmd_pgprot()

pte_pgprot() returns a pgprot_t value by calling pte_flags(). Now that pud_flags() and pmd_flags() work differently from pte_flags(), define pud_pgprot() and pmd_pgprot() for PUD/PMD. Also update pte_pgprot() to remove the masking with PTE_FLAGS_MASK, which is unnecessary since pte_flags() takes

[PATCH v3 7/10] x86/mm: Fix gup_huge_p?d() to handle large PAT bit

gup_huge_pud() and gup_huge_pmd() cast *pud and *pmd to *pte, and use pte_xxx() interfaces to obtain the flags and PFN. However, the pte_xxx() interface does not handle the large PAT bit properly for PUD/PMD. Fix gup_huge_pud() and gup_huge_pmd() to use pud_xxx() and pmd_xxx() interfaces

[PATCH v3 1/10] x86/vdso32: Define PGTABLE_LEVELS to 32bit VDSO

In case of CONFIG_X86_64, vdso32/vclock_gettime.c fakes a 32bit kernel configuration by re-defining it to CONFIG_X86_32. However, it does not re-define CONFIG_PGTABLE_LEVELS leaving it as 4 levels. Fix it by re-defining CONFIG_PGTABLE_LEVELS to 2 as X86_PAE is not set. Signed-off-by: Toshi Kani

[PATCH v3 10/10] x86/mm: Fix the same pgprot handling in try_preserve_large_page()

try_preserve_large_page() checks if new_prot is the same as old_prot. If so, it simply sets do_split to 0, and returns with no-operation. However, old_prot is set as a 4KB pgprot value while new_prot is a large page pgprot value. Now that old_prot is initially set from p?d_pgprot() as a large

[PATCH v3 8/10] x86/mm: Fix try_preserve_large_page() to handle large PAT bit

try_preserve_large_page() is called from __change_page_attr() to change the map attribute by preserving the large page. This function uses pte_pfn() and pte_pgprot() for PUD/PMD, which do not handle the large PAT bit properly. Fix try_preserve_large_page() to use corresponding p?d_pfn() and

[PATCH v3 3/10] x86/asm: Fix pud/pmd interfaces to handle large PAT bit

The PAT bit gets relocated to bit 12 when PUD and PMD mappings are used. This bit 12, however, is not covered by PTE_FLAGS_MASK, which is corrently used for masking pfn and flags for all cases. Fix pud/pmd interfaces to handle pfn and flags properly by using P?D_PAGE_MASK when PUD/PMD mappings

[PATCH v3 6/10] x86/mm: Fix slow_virt_to_phys() to handle large PAT bit

slow_virt_to_phys() calls lookup_address() to obtain *pte and its level. It then calls pte_pfn() to obtain the PFN for any level. This does not result the correct PFN when the large PAT bit is set because pte_pfn() does not mask the large PAT bit properly for PUD/PMD. Fix slow_virt_to_phys() to

[PATCH v3 9/10] x86/mm: Fix __split_large_page() to handle large PAT bit

__split_large_page() is called from __change_page_attr() to change the map attribute by splitting the large page into smaller pages. This function uses pte_pfn() and pte_pgprot() for PUD/PMD, which do not handle the large PAT bit properly. Fix __split_large_page() to use corresponding p?d_pfn()

[PATCH v3 5/10] x86/mm: Fix page table dump to show PAT bit

/sys/kernel/debug/kernel_page_tables does not show the PAT bit for PUD/PMD mappings. This is because walk_pud_level(), walk_pmd_level() and note_page() mask the flags with PTE_FLAGS_MASK, which does not cover their PAT bit, _PAGE_PAT_LARGE. Fix it by replacing the use of PTE_FLAGS_MASK with

From: Kan Liang This patchkit adds the ability to turn off time stamps per event. One usaful case for partial time is to work with per-event callgraph to enable "PEBS threshold > 1" (https://lkml.org/lkml/2015/5/10/196), which can significantly reduce the sampling overhead. The event samples

[PATCH 02/12] perf trace: Do not show syscall tracepoint filter in the --no-syscalls case

From: Arnaldo Carvalho de Melo We were accessing trace->syscalls.events members even when that struct wasn't initialized, i.e. --no-syscalls was specified on the command line, fix it to show that, still in debug mode, when we have an event qualifier list, i.e. when we actually are doing subset

[PATCH 01/12] perf script: No tracepoints? Don't call libtraceevent.

From: Arnaldo Carvalho de Melo The libtraceevent handler (session->tevent) is only initialized when there are tracepoints in a perf.data event list, so do not call pevent_set_function_resolve() in those cases, fixing a segfault. Reported-by: Jiri Olsa Tested-by: Jiri Olsa Cc: Adrian Hunter

[PATCH 05/12] perf trace: Deref sys_enter pointer args with contents from probe:vfs_getname

From: Arnaldo Carvalho de Melo To work like strace and dereference syscall pointer args we need to insert probes (or tracepoints) right after we copy those bytes from userspace. Since we're formatting the syscall args at raw_syscalls:sys_enter time, we need to have a formatter that just stores

[PATCH v2] ioatdma: fix overflow of u16 in ring_reshape

If the allocation order is 16, then the u16 index will overflow and wrap to zero instead of being equal or greater than 1 << 16. The loop condition will always be true, and the loop will run until all the memory resources are depleted. Change the type of index 'i' to u32, so that it is large
