2021-09-03memblock: make memblock_find_in_range method privateMike Rapoport11-103/+69
There are a lot of uses of memblock_find_in_range() along with memblock_reserve() from the times memblock allocation APIs did not exist. memblock_find_in_range() is the very core of memblock allocations, so any future changes to its internal behaviour would mandate updates of all the users outside memblock. Replace the calls to memblock_find_in_range() with an equivalent calls to memblock_phys_alloc() and memblock_phys_alloc_range() and make memblock_find_in_range() private method of memblock. This simplifies the callers, ensures that (unlikely) errors in memblock_reserve() are handled and improves maintainability of memblock_find_in_range().

2021-09-03microblaze: simplify pte_alloc_one_kernel()Mike Rapoport3-23/+8
The microblaze's implementation of pte_alloc_one_kernel() used memblock_alloc_try_nid_raw() along with clear_page() to allocated a zeroed page during early setup. Replace calls of these functions with a call to memblock_alloc_try_nid() that already returns zeroed page and respects the same allocation limits as memblock_alloc_try_nid_raw(). While on it drop early_get_page() wrapper that was only used in pte_alloc_one_kernel().

2021-09-03mm/page_alloc: always initialize memory map for the holesMike Rapoport1-2/+1
Patch series "mm: ensure consistency of memory map poisoning". Currently memory map allocation for FLATMEM case does not poison the struct pages regardless of CONFIG_PAGE_POISON setting. This happens because allocation of the memory map for FLATMEM and SPARSMEM use different memblock functions and those that are used for SPARSMEM case (namely memblock_alloc_try_nid_raw() and memblock_alloc_exact_nid_raw()) implicitly poison the allocated memory. Another side effect of this implicit poisoning is that early setup code that uses the same functions to allocate memory burns cycles for the memory poisoning even if it was not intended. These patches introduce memmap_alloc() wrapper that ensure that the memory map allocation is consistent for different memory models. This patch (of 4): Currently memory map for the holes is initialized only when SPARSEMEM memory model is used. Yet, even with FLATMEM there could be holes in the physical memory layout that have memory map entries. For instance, the memory reserved using e820 API on i386 or "reserved-memory" nodes in device tree would not appear in memblock.memory and hence the struct pages for such holes will be skipped during memory map initialization. These struct pages will be zeroed because the memory map for FLATMEM systems is allocated with memblock_alloc_node() that clears the allocated memory. While zeroed struct pages do not cause immediate problems, the correct behaviour is to initialize every page using __init_single_page(). Besides, enabling page poison for FLATMEM case will trigger PF_POISONED_CHECK() unless the memory map is properly initialized. Make sure init_unavailable_range() is called for both SPARSEMEM and FLATMEM so that struct pages representing memory holes would appear as PG_Reserved with any memory layout.

2021-09-03mm: sparse: pass section_nr to find_memory_blockOhhoon Kwon1-3/+1
With CONFIG_SPARSEMEM_EXTREME enabled, __section_nr() which converts mem_section to section_nr could be costly since it iterates all section roots to check if the given mem_section is in its range. On the other hand, __nr_to_section() which converts section_nr to mem_section can be done in O(1). Let's pass section_nr instead of mem_section ptr to find_memory_block() in order to reduce needless iterations.

2021-09-03mm: remove flush_kernel_dcache_pageChristoph Hellwig11-88/+9
flush_kernel_dcache_page is a rather confusing interface that implements a subset of flush_dcache_page by not being able to properly handle page cache mapped pages. The only callers left are in the exec code as all other previous callers were incorrect as they could have dealt with page cache pages. Replace the calls to flush_kernel_dcache_page with calls to flush_dcache_page, which for all architectures does either exactly the same thing, can contains one or more of the following: 1) an optimization to defer the cache flush for page cache pages not mapped into userspace 2) additional flushing for mapped page cache pages if cache aliases are possible Link: https://lkml.kernel.org/r/20210712060928.4161649-7-hch@lst.de Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Reviewed-by: Ira Weiny <ira.weiny@intel.com> Cc: Alex Shi <alexs@kernel.org> Cc: Geoff Levand <geoff@infradead.org> Cc: Greentime Hu <green.hu@gmail.com> Cc: Guo Ren <guoren@kernel.org> Cc: Helge Deller <deller@gmx.de> Cc: "James E.J.

2021-09-03memcg: enable accounting for ldt_struct objectsVasily Averin1-3/+3
Each task can request own LDT and force the kernel to allocate up to 64Kb memory per-mm. There are legitimate workloads with hundreds of processes and there can be hundreds of workloads running on large machines. The unaccounted memory can cause isolation issues between the workloads particularly on highly utilized machines. It makes sense to account for this objects to restrict the host's memory consumption from inside the memcg-limited container.

2021-09-03mm/gup: remove try_get_page(), call try_get_compound_head() directlyJohn Hubbard1-1/+1
try_get_page() is very similar to try_get_compound_head(), and in fact try_get_page() has fallen a little behind in terms of maintenance: try_get_compound_head() handles speculative page references more thoroughly. There are only two try_get_page() callsites, so just call try_get_compound_head() directly from those, and remove try_get_page() entirely. Also, seeing as how this changes try_get_compound_head() into a non-static function, provide some kerneldoc documentation for it.

2021-09-01parisc: fix crash with signals and allocaMikulas Patocka1-0/+6
I was debugging some crashes on parisc and I found out that there is a crash possibility if a function using alloca is interrupted by a signal. The reason for the crash is that the gcc alloca implementation leaves garbage in the upper 32 bits of the sp register. This normally doesn't matter (the upper bits are ignored because the PSW W-bit is clear), however the signal delivery routine in the kernel uses full 64 bits of sp and it fails with -EFAULT if the upper 32 bits are not zero. I created this program that demonstrates the problem: #include <stdlib.h> #include <unistd.h> #include <signal.h> #include <alloca.h> static __attribute__((noinline,noclone)) void aa(int *size) { void * volatile p = alloca(-*size); while (1) ; } static void handler(int sig) { write(1, "signal delivered\n", 17); _exit(0); } int main(void) { int size = -0x100; signal(SIGALRM, handler); alarm(1); aa(&size); } If you compile it with optimizations, it will crash. The "aa" function has this disassembly: 000106a0 <aa>: 106a0: 08 03 02 41 copy r3,r1 106a4: 08 1e 02 43 copy sp,r3 106a8: 6f c1 00 80 stw,ma r1,40(sp) 106ac: 37 dc 3f c1 ldo -20(sp),ret0 106b0: 0c 7c 12 90 stw ret0,8(r3) 106b4: 0f 40 10 9c ldw 0(r26),ret0 ; ret0 = 0x00000000FFFFFF00 106b8: 97 9c 00 7e subi 3f,ret0,ret0 ; ret0 = 0xFFFFFFFF0000013F 106bc: d7 80 1c 1a depwi 0,31,6,ret0 ; ret0 = 0xFFFFFFFF00000100 106c0: 0b 9e 0a 1e add,l sp,ret0,sp ; sp = 0xFFFFFFFFxxxxxxxx 106c4: e8 1f 1f f7 b,l,n 106c4 <aa+0x24>,r0 This patch fixes the bug by truncating the "usp" variable to 32 bits.

2021-09-01parisc: Fix compile failure when building 64-bit kernel nativelyMasahiro Yamada1-3/+3
Commit 23243c1ace9f ("arch: use cross_compiling to check whether it is a cross build or not") broke 64-bit parisc builds on 32-bit parisc systems. Helge mentioned: - 64-bit parisc userspace is not supported yet [1] - hppa gcc does not support "-m64" flag [2] That means, parisc developers working on a 32-bit parisc machine need to use hppa64-linux-gnu-gcc (cross compiler) for building the 64-bit parisc kernel. After the offending commit, gcc is used in such a case because both $(SRCARCH) and $(SUBARCH) are 'parisc', hence cross_compiling is unset. A correct way is to introduce ARCH=parisc64 because building the 64-bit parisc kernel on a 32-bit parisc system is not exactly a native build, but rather a semi-cross build.

Specifics: - Address 3 PCI device power management issues (Rafael Wysocki). - Add Power Limit4 support for Alder Lake to the Intel RAPL power capping driver (Sumeet Pawnikar). - Add HWP guaranteed performance change notification support to the intel_pstate driver (Srinivas Pandruvada). - Replace deprecated CPU-hotplug functions in code related to power management (Sebastian Andrzej Siewior). - Update CPU PM notifiers to use raw spinlocks (Valentin Schneider). - Add support for 'required-opps' DT property to the generic power domains (genpd) framework and use this property for I2C on ARM64 sc7180 (Rajendra Nayak). - Fix Kconfig issue related to genpd (Geert Uytterhoeven). - Increase energy calculation precision in the Energy Model (Lukasz Luba). - Fix kobject deletion in the exit code of the schedutil cpufreq governor (Kevin Hao). - Unmark some functions as kernel-doc in the PM core to avoid false-positive documentation build warnings (Randy Dunlap). - Check RTC features instead of ops in suspend_test Alexandre Belloni)" * tag 'pm-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM: domains: Fix domain attach for CONFIG_PM_OPP=n powercap: Add Power Limit4 support for Alder Lake SoC cpufreq: intel_pstate: Process HWP Guaranteed change notification thermal: intel: Allow processing of HWP interrupt notifier: Remove atomic_notifier_call_chain_robust() PM: cpu: Make notifier chain use a raw_spinlock_t PM: sleep: unmark 'state' functions as kernel-doc arm64: dts: sc7180: Add required-opps for i2c PM: domains: Add support for 'required-opps' to set default perf state opp: Don't print an error if required-opps is missing cpufreq: schedutil: Use kobject release() method to free sugov_tunables PM: EM: Increase energy calculation precision PM: sleep: check RTC features instead of ops in suspend_test PM: sleep: s2idle: Replace deprecated CPU-hotplug functions cpufreq: Replace deprecated CPU-hotplug functions powercap: intel_rapl: Replace deprecated CPU-hotplug functions PCI: PM: Enable PME if it can be signaled from D3cold PCI: PM: Avoid forcing PCI_D0 for wakeup reasons inconsistently PCI: Use pci_update_current_state() in pci_enable_device_flags()
