 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:crypto: caam - Prevent crash on suspend with iMX8QM / iMX8ULPSince the CAAM on these SoCs is managed by another ARM core, called theSECO (Security Controller) on iMX8QM and Secure Enclave on iMX8ULP, whichalso reserves access to register page 0 suspend operations cannot touchthis page.This is similar to when running OPTEE, where OPTEE will reserve page 0.Track this situation using a new state variable no_page0, reflecting ifpage 0 is reserved elsewhere, either by other management cores in SoC orby OPTEE.Replace the optee_en check in suspend/resume with the new check.optee_en cannot go away as it s needed elsewhere to gate OPTEE specificsituations.Fixes the following splat at suspend:    Internal error: synchronous external abort: 0000000096000010 [#1] SMP    Hardware name: Freescale i.MX8QXP ACU6C (DT)    pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--)    pc : readl+0x0/0x18    lr : rd_reg32+0x18/0x3c    sp : ffffffc08192ba20    x29: ffffffc08192ba20 x28: ffffff8025190000 x27: 0000000000000000    x26: ffffffc0808ae808 x25: ffffffc080922338 x24: ffffff8020e89090    x23: 0000000000000000 x22: ffffffc080922000 x21: ffffff8020e89010    x20: ffffffc080387ef8 x19: ffffff8020e89010 x18: 000000005d8000d5    x17: 0000000030f35963 x16: 000000008f785f3f x15: 000000003b8ef57c    x14: 00000000c418aef8 x13: 00000000f5fea526 x12: 0000000000000001    x11: 0000000000000002 x10: 0000000000000001 x9 : 0000000000000000    x8 : ffffff8025190870 x7 : ffffff8021726880 x6 : 0000000000000002    x5 : ffffff80217268f0 x4 : ffffff8021726880 x3 : ffffffc081200000    x2 : 0000000000000001 x1 : ffffff8020e89010 x0 : ffffffc081200004    Call trace:     readl+0x0/0x18     caam_ctrl_suspend+0x30/0xdc     dpm_run_callback.constprop.0+0x24/0x5c     device_suspend+0x170/0x2e8     dpm_suspend+0xa0/0x104     dpm_suspend_start+0x48/0x50     suspend_devices_and_enter+0x7c/0x45c     pm_suspend+0x148/0x160     state_store+0xb4/0xf8     kobj_attr_store+0x14/0x24     sysfs_kf_write+0x38/0x48     kernfs_fop_write_iter+0xb4/0x178     vfs_write+0x118/0x178     ksys_write+0x6c/0xd0     __arm64_sys_write+0x14/0x1c     invoke_syscall.constprop.0+0x64/0xb0     do_el0_svc+0x90/0xb0     el0_svc+0x18/0x44     el0t_64_sync_handler+0x88/0x124     el0t_64_sync+0x150/0x154    Code: 88dffc21 88dffc21 5ac00800 d65f03c0 (b9400000)
