Jarkko Sakkinen 77779d1258 tpm: Change to kvalloc() in eventlog/acpi.c ... [ Upstream commit a3a860bc0fd6c07332e4911cf9a238d20de90173 ] The following failure was reported on HPE ProLiant D320: [ 10.693310][ T1] tpm_tis STM0925:00: 2.0 TPM (device-id 0x3, rev-id 0) [ 10.848132][ T1] ------------[ cut here ]------------ [ 10.853559][ T1] WARNING: CPU: 59 PID: 1 at mm/page_alloc.c:4727 __alloc_pages_noprof+0x2ca/0x330 [ 10.862827][ T1] Modules linked in: [ 10.866671][ T1] CPU: 59 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.12.0-lp155.2.g52785e2-default #1 openSUSE Tumbleweed (unreleased) 588cd98293a7c9eba9013378d807364c088c9375 [ 10.882741][ T1] Hardware name: HPE ProLiant DL320 Gen12/ProLiant DL320 Gen12, BIOS 1.20 10/28/2024 [ 10.892170][ T1] RIP: 0010:__alloc_pages_noprof+0x2ca/0x330 [ 10.898103][ T1] Code: 24 08 e9 4a fe ff ff e8 34 36 fa ff e9 88 fe ff ff 83 fe 0a 0f 86 b3 fd ff ff 80 3d 01 e7 ce 01 00 75 09 c6 05 f8 e6 ce 01 01 <0f> 0b 45 31 ff e9 e5 fe ff ff f7 c2 00 00 08 00 75 42 89 d9 80 e1 [ 10.917750][ T1] RSP: 0000:ffffb7cf40077980 EFLAGS: 00010246 [ 10.923777][ T1] RAX: 0000000000000000 RBX: 0000000000040cc0 RCX: 0000000000000000 [ 10.931727][ T1] RDX: 0000000000000000 RSI: 000000000000000c RDI: 0000000000040cc0 The above transcript shows that ACPI pointed a 16 MiB buffer for the log events because RSI maps to the 'order' parameter of __alloc_pages_noprof(). Address the bug by moving from devm_kmalloc() to devm_add_action() and kvmalloc() and devm_add_action().
